>-+                            Preamble
>-+
>-+  The licenses for most software are designed to take away your
>-+freedom to share and change it.  By contrast, the GNU General Public
>-+Licenses are intended to guarantee your freedom to share and change
>-+free software--to make sure the software is free for all its users.
>-+
>-+  This license, the Lesser General Public License, applies to some
>-+specially designated software packages--typically libraries--of the
>-+Free Software Foundation and other authors who decide to use it.  You
>-+can use it too, but we suggest you first think carefully about whether
>-+this license or the ordinary General Public License is the better
>-+strategy to use in any particular case, based on the explanations below.
>-+
>-+  When we speak of free software, we are referring to freedom of use,
>-+not price.  Our General Public Licenses are designed to make sure that
>-+you have the freedom to distribute copies of free software (and charge
>-+for this service if you wish); that you receive source code or can get
>-+it if you want it; that you can change the software and use pieces of
>-+it in new free programs; and that you are informed that you can do
>-+these things.
>-+
>-+  To protect your rights, we need to make restrictions that forbid
>-+distributors to deny you these rights or to ask you to surrender these
>-+rights.  These restrictions translate to certain responsibilities for
>-+you if you distribute copies of the library or if you modify it.
>-+
>-+  For example, if you distribute copies of the library, whether gratis
>-+or for a fee, you must give the recipients all the rights that we gave
>-+you.  You must make sure that they, too, receive or can get the source
>-+code.  If you link other code with the library, you must provide
>-+complete object files to the recipients, so that they can relink them
>-+with the library after making changes to the library and recompiling
>-+it.  And you must show them these terms so they know their rights.
>-+
>-+  We protect your rights with a two-step method: (1) we copyright the
>-+library, and (2) we offer you this license, which gives you legal
>-+permission to copy, distribute and/or modify the library.
>-+
>-+  To protect each distributor, we want to make it very clear that
>-+there is no warranty for the free library.  Also, if the library is
>-+modified by someone else and passed on, the recipients should know
>-+that what they have is not the original version, so that the original
>-+author's reputation will not be affected by problems that might be
>-+introduced by others.
>-+
>-+  Finally, software patents pose a constant threat to the existence of
>-+any free program.  We wish to make sure that a company cannot
>-+effectively restrict the users of a free program by obtaining a
>-+restrictive license from a patent holder.  Therefore, we insist that
>-+any patent license obtained for a version of the library must be
>-+consistent with the full freedom of use specified in this license.
>-+
>-+  Most GNU software, including some libraries, is covered by the
>-+ordinary GNU General Public License.  This license, the GNU Lesser
>-+General Public License, applies to certain designated libraries, and
>-+is quite different from the ordinary General Public License.  We use
>-+this license for certain libraries in order to permit linking those
>-+libraries into non-free programs.
>-+
>-+  When a program is linked with a library, whether statically or using
>-+a shared library, the combination of the two is legally speaking a
>-+combined work, a derivative of the original library.  The ordinary
>-+General Public License therefore permits such linking only if the
>-+entire combination fits its criteria of freedom.  The Lesser General
>-+Public License permits more lax criteria for linking other code with
>-+the library.
>-+
>-+  We call this license the "Lesser" General Public License because it
>-+does Less to protect the user's freedom than the ordinary General
>-+Public License.  It also provides other free software developers Less
>-+of an advantage over competing non-free programs.  These disadvantages
>-+are the reason we use the ordinary General Public License for many
>-+libraries.  However, the Lesser license provides advantages in certain
>-+special circumstances.
>-+
>-+  For example, on rare occasions, there may be a special need to
>-+encourage the widest possible use of a certain library, so that it becomes
>-+a de-facto standard.  To achieve this, non-free programs must be
>-+allowed to use the library.  A more frequent case is that a free
>-+library does the same job as widely used non-free libraries.  In this
>-+case, there is little to gain by limiting the free library to free
>-+software only, so we use the Lesser General Public License.
>-+
>-+  In other cases, permission to use a particular library in non-free
>-+programs enables a greater number of people to use a large body of
>-+free software.  For example, permission to use the GNU C Library in
>-+non-free programs enables many more people to use the whole GNU
>-+operating system, as well as its variant, the GNU/Linux operating
>-+system.
>-+
>-+  Although the Lesser General Public License is Less protective of the
>-+users' freedom, it does ensure that the user of a program that is
>-+linked with the Library has the freedom and the wherewithal to run
>-+that program using a modified version of the Library.
>-+
>-+  The precise terms and conditions for copying, distribution and
>-+modification follow.  Pay close attention to the difference between a
>-+"work based on the library" and a "work that uses the library".  The
>-+former contains code derived from the library, whereas the latter must
>-+be combined with the library in order to run.
>-+
>-+                  GNU LESSER GENERAL PUBLIC LICENSE
>-+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
>-+
>-+  0. This License Agreement applies to any software library or other
>-+program which contains a notice placed by the copyright holder or
>-+other authorized party saying it may be distributed under the terms of
>-+this Lesser General Public License (also called "this License").
>-+Each licensee is addressed as "you".
>-+
>-+  A "library" means a collection of software functions and/or data
>-+prepared so as to be conveniently linked with application programs
>-+(which use some of those functions and data) to form executables.
>-+
>-+  The "Library", below, refers to any such software library or work
>-+which has been distributed under these terms.  A "work based on the
>-+Library" means either the Library or any derivative work under
>-+copyright law: that is to say, a work containing the Library or a
>-+portion of it, either verbatim or with modifications and/or translated
>-+straightforwardly into another language.  (Hereinafter, translation is
>-+included without limitation in the term "modification".)
>-+
>-+  "Source code" for a work means the preferred form of the work for
>-+making modifications to it.  For a library, complete source code means
>-+all the source code for all modules it contains, plus any associated
>-+interface definition files, plus the scripts used to control compilation
>-+and installation of the library.
>-+
>-+  Activities other than copying, distribution and modification are not
>-+covered by this License; they are outside its scope.  The act of
>-+running a program using the Library is not restricted, and output from
>-+such a program is covered only if its contents constitute a work based
>-+on the Library (independent of the use of the Library in a tool for
>-+writing it).  Whether that is true depends on what the Library does
>-+and what the program that uses the Library does.
>-+
>-+  1. You may copy and distribute verbatim copies of the Library's
>-+complete source code as you receive it, in any medium, provided that
>-+you conspicuously and appropriately publish on each copy an
>-+appropriate copyright notice and disclaimer of warranty; keep intact
>-+all the notices that refer to this License and to the absence of any
>-+warranty; and distribute a copy of this License along with the
>-+Library.
>-+
>-+  You may charge a fee for the physical act of transferring a copy,
>-+and you may at your option offer warranty protection in exchange for a
>-+fee.
>-+
>-+  2. You may modify your copy or copies of the Library or any portion
>-+of it, thus forming a work based on the Library, and copy and
>-+distribute such modifications or work under the terms of Section 1
>-+above, provided that you also meet all of these conditions:
>-+
>-+    a) The modified work must itself be a software library.
>-+
>-+    b) You must cause the files modified to carry prominent notices
>-+    stating that you changed the files and the date of any change.
>-+
>-+    c) You must cause the whole of the work to be licensed at no
>-+    charge to all third parties under the terms of this License.
>-+
>-+    d) If a facility in the modified Library refers to a function or a
>-+    table of data to be supplied by an application program that uses
>-+    the facility, other than as an argument passed when the facility
>-+    is invoked, then you must make a good faith effort to ensure that,
>-+    in the event an application does not supply such function or
>-+    table, the facility still operates, and performs whatever part of
>-+    its purpose remains meaningful.
>-+
>-+    (For example, a function in a library to compute square roots has
>-+    a purpose that is entirely well-defined independent of the
>-+    application.  Therefore, Subsection 2d requires that any
>-+    application-supplied function or table used by this function must
>-+    be optional: if the application does not supply it, the square
>-+    root function must still compute square roots.)
>-+
>-+These requirements apply to the modified work as a whole.  If
>-+identifiable sections of that work are not derived from the Library,
>-+and can be reasonably considered independent and separate works in
>-+themselves, then this License, and its terms, do not apply to those
>-+sections when you distribute them as separate works.  But when you
>-+distribute the same sections as part of a whole which is a work based
>-+on the Library, the distribution of the whole must be on the terms of
>-+this License, whose permissions for other licensees extend to the
>-+entire whole, and thus to each and every part regardless of who wrote
>-+it.
>-+
>-+Thus, it is not the intent of this section to claim rights or contest
>-+your rights to work written entirely by you; rather, the intent is to
>-+exercise the right to control the distribution of derivative or
>-+collective works based on the Library.
>-+
>-+In addition, mere aggregation of another work not based on the Library
>-+with the Library (or with a work based on the Library) on a volume of
>-+a storage or distribution medium does not bring the other work under
>-+the scope of this License.
>-+
>-+  3. You may opt to apply the terms of the ordinary GNU General Public
>-+License instead of this License to a given copy of the Library.  To do
>-+this, you must alter all the notices that refer to this License, so
>-+that they refer to the ordinary GNU General Public License, version 2,
>-+instead of to this License.  (If a newer version than version 2 of the
>-+ordinary GNU General Public License has appeared, then you can specify
>-+that version instead if you wish.)  Do not make any other change in
>-+these notices.
>-+
>-+  Once this change is made in a given copy, it is irreversible for
>-+that copy, so the ordinary GNU General Public License applies to all
>-+subsequent copies and derivative works made from that copy.
>-+
>-+  This option is useful when you wish to copy part of the code of
>-+the Library into a program that is not a library.
>-+
>-+  4. You may copy and distribute the Library (or a portion or
>-+derivative of it, under Section 2) in object code or executable form
>-+under the terms of Sections 1 and 2 above provided that you accompany
>-+it with the complete corresponding machine-readable source code, which
>-+must be distributed under the terms of Sections 1 and 2 above on a
>-+medium customarily used for software interchange.
>-+
>-+  If distribution of object code is made by offering access to copy
>-+from a designated place, then offering equivalent access to copy the
>-+source code from the same place satisfies the requirement to
>-+distribute the source code, even though third parties are not
>-+compelled to copy the source along with the object code.
>-+
>-+  5. A program that contains no derivative of any portion of the
>-+Library, but is designed to work with the Library by being compiled or
>-+linked with it, is called a "work that uses the Library".  Such a
>-+work, in isolation, is not a derivative work of the Library, and
>-+therefore falls outside the scope of this License.
>-+
>-+  However, linking a "work that uses the Library" with the Library
>-+creates an executable that is a derivative of the Library (because it
>-+contains portions of the Library), rather than a "work that uses the
>-+library".  The executable is therefore covered by this License.
>-+Section 6 states terms for distribution of such executables.
>-+
>-+  When a "work that uses the Library" uses material from a header file
>-+that is part of the Library, the object code for the work may be a
>-+derivative work of the Library even though the source code is not.
>-+Whether this is true is especially significant if the work can be
>-+linked without the Library, or if the work is itself a library.  The
>-+threshold for this to be true is not precisely defined by law.
>-+
>-+  If such an object file uses only numerical parameters, data
>-+structure layouts and accessors, and small macros and small inline
>-+functions (ten lines or less in length), then the use of the object
>-+file is unrestricted, regardless of whether it is legally a derivative
>-+work.  (Executables containing this object code plus portions of the
>-+Library will still fall under Section 6.)
>-+
>-+  Otherwise, if the work is a derivative of the Library, you may
>-+distribute the object code for the work under the terms of Section 6.
>-+Any executables containing that work also fall under Section 6,
>-+whether or not they are linked directly with the Library itself.
>-+
>-+  6. As an exception to the Sections above, you may also combine or
>-+link a "work that uses the Library" with the Library to produce a
>-+work containing portions of the Library, and distribute that work
>-+under terms of your choice, provided that the terms permit
>-+modification of the work for the customer's own use and reverse
>-+engineering for debugging such modifications.
>-+
>-+  You must give prominent notice with each copy of the work that the
>-+Library is used in it and that the Library and its use are covered by
>-+this License.  You must supply a copy of this License.  If the work
>-+during execution displays copyright notices, you must include the
>-+copyright notice for the Library among them, as well as a reference
>-+directing the user to the copy of this License.  Also, you must do one
>-+of these things:
>-+
>-+    a) Accompany the work with the complete corresponding
>-+    machine-readable source code for the Library including whatever
>-+    changes were used in the work (which must be distributed under
>-+    Sections 1 and 2 above); and, if the work is an executable linked
>-+    with the Library, with the complete machine-readable "work that
>-+    uses the Library", as object code and/or source code, so that the
>-+    user can modify the Library and then relink to produce a modified
>-+    executable containing the modified Library.  (It is understood
>-+    that the user who changes the contents of definitions files in the
>-+    Library will not necessarily be able to recompile the application
>-+    to use the modified definitions.)
>-+
>-+    b) Use a suitable shared library mechanism for linking with the
>-+    Library.  A suitable mechanism is one that (1) uses at run time a
>-+    copy of the library already present on the user's computer system,
>-+    rather than copying library functions into the executable, and (2)
>-+    will operate properly with a modified version of the library, if
>-+    the user installs one, as long as the modified version is
>-+    interface-compatible with the version that the work was made with.
>-+
>-+    c) Accompany the work with a written offer, valid for at
>-+    least three years, to give the same user the materials
>-+    specified in Subsection 6a, above, for a charge no more
>-+    than the cost of performing this distribution.
>-+
>-+    d) If distribution of the work is made by offering access to copy
>-+    from a designated place, offer equivalent access to copy the above
>-+    specified materials from the same place.
>-+
>-+    e) Verify that the user has already received a copy of these
>-+    materials or that you have already sent this user a copy.
>-+
>-+  For an executable, the required form of the "work that uses the
>-+Library" must include any data and utility programs needed for
>-+reproducing the executable from it.  However, as a special exception,
>-+the materials to be distributed need not include anything that is
>-+normally distributed (in either source or binary form) with the major
>-+components (compiler, kernel, and so on) of the operating system on
>-+which the executable runs, unless that component itself accompanies
>-+the executable.
>-+
>-+  It may happen that this requirement contradicts the license
>-+restrictions of other proprietary libraries that do not normally
>-+accompany the operating system.  Such a contradiction means you cannot
>-+use both them and the Library together in an executable that you
>-+distribute.
>-+
>-+  7. You may place library facilities that are a work based on the
>-+Library side-by-side in a single library together with other library
>-+facilities not covered by this License, and distribute such a combined
>-+library, provided that the separate distribution of the work based on
>-+the Library and of the other library facilities is otherwise
>-+permitted, and provided that you do these two things:
>-+
>-+    a) Accompany the combined library with a copy of the same work
>-+    based on the Library, uncombined with any other library
>-+    facilities.  This must be distributed under the terms of the
>-+    Sections above.
>-+
>-+    b) Give prominent notice with the combined library of the fact
>-+    that part of it is a work based on the Library, and explaining
>-+    where to find the accompanying uncombined form of the same work.
>-+
>-+  8. You may not copy, modify, sublicense, link with, or distribute
>-+the Library except as expressly provided under this License.  Any
>-+attempt otherwise to copy, modify, sublicense, link with, or
>-+distribute the Library is void, and will automatically terminate your
>-+rights under this License.  However, parties who have received copies,
>-+or rights, from you under this License will not have their licenses
>-+terminated so long as such parties remain in full compliance.
>-+
>-+  9. You are not required to accept this License, since you have not
>-+signed it.  However, nothing else grants you permission to modify or
>-+distribute the Library or its derivative works.  These actions are
>-+prohibited by law if you do not accept this License.  Therefore, by
>-+modifying or distributing the Library (or any work based on the
>-+Library), you indicate your acceptance of this License to do so, and
>-+all its terms and conditions for copying, distributing or modifying
>-+the Library or works based on it.
>-+
>-+  10. Each time you redistribute the Library (or any work based on the
>-+Library), the recipient automatically receives a license from the
>-+original licensor to copy, distribute, link with or modify the Library
>-+subject to these terms and conditions.  You may not impose any further
>-+restrictions on the recipients' exercise of the rights granted herein.
>-+You are not responsible for enforcing compliance by third parties with
>-+this License.
>-+
>-+  11. If, as a consequence of a court judgment or allegation of patent
>-+infringement or for any other reason (not limited to patent issues),
>-+conditions are imposed on you (whether by court order, agreement or
>-+otherwise) that contradict the conditions of this License, they do not
>-+excuse you from the conditions of this License.  If you cannot
>-+distribute so as to satisfy simultaneously your obligations under this
>-+License and any other pertinent obligations, then as a consequence you
>-+may not distribute the Library at all.  For example, if a patent
>-+license would not permit royalty-free redistribution of the Library by
>-+all those who receive copies directly or indirectly through you, then
>-+the only way you could satisfy both it and this License would be to
>-+refrain entirely from distribution of the Library.
>-+
>-+If any portion of this section is held invalid or unenforceable under any
>-+particular circumstance, the balance of the section is intended to apply,
>-+and the section as a whole is intended to apply in other circumstances.
>-+
>-+It is not the purpose of this section to induce you to infringe any
>-+patents or other property right claims or to contest validity of any
>-+such claims; this section has the sole purpose of protecting the
>-+integrity of the free software distribution system which is
>-+implemented by public license practices.  Many people have made
>-+generous contributions to the wide range of software distributed
>-+through that system in reliance on consistent application of that
>-+system; it is up to the author/donor to decide if he or she is willing
>-+to distribute software through any other system and a licensee cannot
>-+impose that choice.
>-+
>-+This section is intended to make thoroughly clear what is believed to
>-+be a consequence of the rest of this License.
>-+
>-+  12. If the distribution and/or use of the Library is restricted in
>-+certain countries either by patents or by copyrighted interfaces, the
>-+original copyright holder who places the Library under this License may add
>-+an explicit geographical distribution limitation excluding those countries,
>-+so that distribution is permitted only in or among countries not thus
>-+excluded.  In such case, this License incorporates the limitation as if
>-+written in the body of this License.
>-+
>-+  13. The Free Software Foundation may publish revised and/or new
>-+versions of the Lesser General Public License from time to time.
>-+Such new versions will be similar in spirit to the present version,
>-+but may differ in detail to address new problems or concerns.
>-+
>-+Each version is given a distinguishing version number.  If the Library
>-+specifies a version number of this License which applies to it and
>-+"any later version", you have the option of following the terms and
>-+conditions either of that version or of any later version published by
>-+the Free Software Foundation.  If the Library does not specify a
>-+license version number, you may choose any version ever published by
>-+the Free Software Foundation.
>-+
>-+  14. If you wish to incorporate parts of the Library into other free
>-+programs whose distribution conditions are incompatible with these,
>-+write to the author to ask for permission.  For software which is
>-+copyrighted by the Free Software Foundation, write to the Free
>-+Software Foundation; we sometimes make exceptions for this.  Our
>-+decision will be guided by the two goals of preserving the free status
>-+of all derivatives of our free software and of promoting the sharing
>-+and reuse of software generally.
>-+
>-+                            NO WARRANTY
>-+
>-+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
>-+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
>-+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
>-+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
>-+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
>-+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
>-+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
>-+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
>-+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
>-+
>-+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
>-+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
>-+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
>-+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
>-+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
>-+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
>-+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
>-+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
>-+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
>-+DAMAGES.
>-+
>-+                     END OF TERMS AND CONDITIONS
>-+
>-+           How to Apply These Terms to Your New Libraries
>-+
>-+  If you develop a new library, and you want it to be of the greatest
>-+possible use to the public, we recommend making it free software that
>-+everyone can redistribute and change.  You can do so by permitting
>-+redistribution under these terms (or, alternatively, under the terms of the
>-+ordinary General Public License).
>-+
>-+  To apply these terms, attach the following notices to the library.  It is
>-+safest to attach them to the start of each source file to most effectively
>-+convey the exclusion of warranty; and each file should have at least the

>-+/**
>-+ * @ingroup libavc
>-+ * @defgroup lavc_encdec send/receive encoding and decoding API overview
>-+ * @{
>-+ *
>-+ * The avcodec_send_packet()/avcodec_receive_frame()/avcodec_send_frame()/
>-+ * avcodec_receive_packet() functions provide an encode/decode API, which
>-+ * decouples input and output.
>-+ *
>-+ * The API is very similar for encoding/decoding and audio/video, and works as
>-+ * follows:
>-+ * - Set up and open the AVCodecContext as usual.
>-+ * - Send valid input:
>-+ *   - For decoding, call avcodec_send_packet() to give the decoder raw
>-+ *     compressed data in an AVPacket.
>-+ *   - For encoding, call avcodec_send_frame() to give the encoder an AVFrame
>-+ *     containing uncompressed audio or video.
>-+ *   In both cases, it is recommended that AVPackets and AVFrames are
>-+ *   refcounted, or libavcodec might have to copy the input data. (libavformat
>-+ *   always returns refcounted AVPackets, and av_frame_get_buffer() allocates
>-+ *   refcounted AVFrames.)
>-+ * - Receive output in a loop. Periodically call one of the avcodec_receive_*()
>-+ *   functions and process their output:
>-+ *   - For decoding, call avcodec_receive_frame(). On success, it will return
>-+ *     an AVFrame containing uncompressed audio or video data.
>-+ *   - For encoding, call avcodec_receive_packet(). On success, it will return
>-+ *     an AVPacket with a compressed frame.
>-+ *   Repeat this call until it returns AVERROR(EAGAIN) or an error. The
>-+ *   AVERROR(EAGAIN) return value means that new input data is required to
>-+ *   return new output. In this case, continue with sending input. For each
>-+ *   input frame/packet, the codec will typically return 1 output frame/packet,
>-+ *   but it can also be 0 or more than 1.
>-+ *
>-+ * At the beginning of decoding or encoding, the codec might accept multiple
>-+ * input frames/packets without returning a frame, until its internal buffers
>-+ * are filled. This situation is handled transparently if you follow the steps
>-+ * outlined above.
>-+ *
>-+ * In theory, sending input can result in EAGAIN - this should happen only if
>-+ * not all output was received. You can use this to structure alternative decode
>-+ * or encode loops other than the one suggested above. For example, you could
>-+ * try sending new input on each iteration, and try to receive output if that
>-+ * returns EAGAIN.
>-+ *
>-+ * End of stream situations. These require "flushing" (aka draining) the codec,
>-+ * as the codec might buffer multiple frames or packets internally for
>-+ * performance or out of necessity (consider B-frames).
>-+ * This is handled as follows:
>-+ * - Instead of valid input, send NULL to the avcodec_send_packet() (decoding)
>-+ *   or avcodec_send_frame() (encoding) functions. This will enter draining
>-+ *   mode.
>-+ * - Call avcodec_receive_frame() (decoding) or avcodec_receive_packet()
>-+ *   (encoding) in a loop until AVERROR_EOF is returned. The functions will
>-+ *   not return AVERROR(EAGAIN), unless you forgot to enter draining mode.
>-+ * - Before decoding can be resumed again, the codec has to be reset with
>-+ *   avcodec_flush_buffers().
>-+ *
>-+ * Using the API as outlined above is highly recommended. But it is also
>-+ * possible to call functions outside of this rigid schema. For example, you can
>-+ * call avcodec_send_packet() repeatedly without calling
>-+ * avcodec_receive_frame(). In this case, avcodec_send_packet() will succeed
>-+ * until the codec's internal buffer has been filled up (which is typically of
>-+ * size 1 per output frame, after initial input), and then reject input with
>-+ * AVERROR(EAGAIN). Once it starts rejecting input, you have no choice but to
>-+ * read at least some output.
>-+ *
>-+ * Not all codecs will follow a rigid and predictable dataflow; the only
>-+ * guarantee is that an AVERROR(EAGAIN) return value on a send/receive call on
>-+ * one end implies that a receive/send call on the other end will succeed, or
>-+ * at least will not fail with AVERROR(EAGAIN). In general, no codec will
>-+ * permit unlimited buffering of input or output.
>-+ *
>-+ * This API replaces the following legacy functions:
>-+ * - avcodec_decode_video2() and avcodec_decode_audio4():
>-+ *   Use avcodec_send_packet() to feed input to the decoder, then use
>-+ *   avcodec_receive_frame() to receive decoded frames after each packet.
>-+ *   Unlike with the old video decoding API, multiple frames might result from
>-+ *   a packet. For audio, splitting the input packet into frames by partially
>-+ *   decoding packets becomes transparent to the API user. You never need to
>-+ *   feed an AVPacket to the API twice (unless it is rejected with AVERROR(EAGAIN) - then
>-+ *   no data was read from the packet).
>-+ *   Additionally, sending a flush/draining packet is required only once.
>-+ * - avcodec_encode_video2()/avcodec_encode_audio2():
>-+ *   Use avcodec_send_frame() to feed input to the encoder, then use
>-+ *   avcodec_receive_packet() to receive encoded packets.
>-+ *   Providing user-allocated buffers for avcodec_receive_packet() is not
>-+ *   possible.
>-+ * - The new API does not handle subtitles yet.
>-+ *
>-+ * Mixing new and old function calls on the same AVCodecContext is not allowed,
>-+ * and will result in undefined behavior.
>-+ *
>-+ * Some codecs might require using the new API; using the old API will return
>-+ * an error when calling it. All codecs support the new API.
>-+ *
>-+ * A codec is not allowed to return AVERROR(EAGAIN) for both sending and receiving. This
>-+ * would be an invalid state, which could put the codec user into an endless
>-+ * loop. The API has no concept of time either: it cannot happen that trying to
>-+ * do avcodec_send_packet() results in AVERROR(EAGAIN), but a repeated call 1 second
>-+ * later accepts the packet (with no other receive/flush API calls involved).
>-+ * The API is a strict state machine, and the passage of time is not supposed
>-+ * to influence it. Some timing-dependent behavior might still be deemed
>-+ * acceptable in certain cases. But it must never result in both send/receive
>-+ * returning EAGAIN at the same time at any point. It must also absolutely be
>-+ * avoided that the current state is "unstable" and can "flip-flop" between
>-+ * the send/receive APIs allowing progress. For example, it's not allowed that
>-+ * the codec randomly decides that it actually wants to consume a packet now
>-+ * instead of returning a frame, after it just returned AVERROR(EAGAIN) on an
>-+ * avcodec_send_packet() call.

>-+ * Create and return a AVHWFramesContext with values adequate for hardware
>-+ * decoding. This is meant to get called from the get_format callback, and is
>-+ * a helper for preparing a AVHWFramesContext for AVCodecContext.hw_frames_ctx.
>-+ * This API is for decoding with certain hardware acceleration modes/APIs only.
>-+ *
>-+ * The returned AVHWFramesContext is not initialized. The caller must do this
>-+ * with av_hwframe_ctx_init().
>-+ *
>-+ * Calling this function is not a requirement, but makes it simpler to avoid
>-+ * codec or hardware API specific details when manually allocating frames.
>-+ *
>-+ * Alternatively to this, an API user can set AVCodecContext.hw_device_ctx,
>-+ * which sets up AVCodecContext.hw_frames_ctx fully automatically, and makes
>-+ * it unnecessary to call this function or having to care about
>-+ * AVHWFramesContext initialization at all.
>-+ *
>-+ * There are a number of requirements for calling this function:
>-+ *
>-+ * - It must be called from get_format with the same avctx parameter that was
>-+ *   passed to get_format. Calling it outside of get_format is not allowed, and
>-+ *   can trigger undefined behavior.
>-+ * - The function is not always supported (see description of return values).
>-+ *   Even if this function returns successfully, hwaccel initialization could
>-+ *   fail later. (The degree to which implementations check whether the stream
>-+ *   is actually supported varies. Some do this check only after the user's
>-+ *   get_format callback returns.)
>-+ * - The hw_pix_fmt must be one of the choices suggested by get_format. If the
>-+ *   user decides to use a AVHWFramesContext prepared with this API function,
>-+ *   the user must return the same hw_pix_fmt from get_format.
>-+ * - The device_ref passed to this function must support the given hw_pix_fmt.
>-+ * - After calling this API function, it is the user's responsibility to
>-+ *   initialize the AVHWFramesContext (returned by the out_frames_ref parameter),
>-+ *   and to set AVCodecContext.hw_frames_ctx to it. If done, this must be done
>-+ *   before returning from get_format (this is implied by the normal
>-+ *   AVCodecContext.hw_frames_ctx API rules).
>-+ * - The AVHWFramesContext parameters may change every time time get_format is
>-+ *   called. Also, AVCodecContext.hw_frames_ctx is reset before get_format. So
>-+ *   you are inherently required to go through this process again on every
>-+ *   get_format call.
>-+ * - It is perfectly possible to call this function without actually using
>-+ *   the resulting AVHWFramesContext. One use-case might be trying to reuse a
>-+ *   previously initialized AVHWFramesContext, and calling this API function
>-+ *   only to test whether the required frame parameters have changed.
>-+ * - Fields that use dynamically allocated values of any kind must not be set
>-+ *   by the user unless setting them is explicitly allowed by the documentation.
>-+ *   If the user sets AVHWFramesContext.free and AVHWFramesContext.user_opaque,
>-+ *   the new free callback must call the potentially set previous free callback.
>-+ *   This API call may set any dynamically allocated fields, including the free
>-+ *   callback.
>-+ *
>-+ * The function will set at least the following fields on AVHWFramesContext
>-+ * (potentially more, depending on hwaccel API):
>-+ *
>-+ * - All fields set by av_hwframe_ctx_alloc().
>-+ * - Set the format field to hw_pix_fmt.
>-+ * - Set the sw_format field to the most suited and most versatile format. (An
>-+ *   implication is that this will prefer generic formats over opaque formats
>-+ *   with arbitrary restrictions, if possible.)
>-+ * - Set the width/height fields to the coded frame size, rounded up to the
>-+ *   API-specific minimum alignment.
>-+ * - Only _if_ the hwaccel requires a pre-allocated pool: set the initial_pool_size
>-+ *   field to the number of maximum reference surfaces possible with the codec,
>-+ *   plus 1 surface for the user to work (meaning the user can safely reference
>-+ *   at most 1 decoded surface at a time), plus additional buffering introduced
>-+ *   by frame threading. If the hwaccel does not require pre-allocation, the
>-+ *   field is left to 0, and the decoder will allocate new surfaces on demand
>-+ *   during decoding.
>-+ * - Possibly AVHWFramesContext.hwctx fields, depending on the underlying
>-+ *   hardware API.
>-+ *
>-+ * Essentially, out_frames_ref returns the same as av_hwframe_ctx_alloc(), but
>-+ * with basic frame parameters set.
>-+ *
>-+ * The function is stateless, and does not change the AVCodecContext or the

>-+ * @section ffmpeg_intro Introduction
>-+ *
>-+ * This document describes the usage of the different libraries
>-+ * provided by FFmpeg.
>-+ *
>-+ * @li @ref libavc "libavcodec" encoding/decoding library
>-+ * @li @ref lavfi "libavfilter" graph-based frame editing library
>-+ * @li @ref libavf "libavformat" I/O and muxing/demuxing library

>-+ * @li @ref lpp  "libpostproc" post processing library
>-+ * @li @ref libsws "libswscale" color conversion and scaling library
>-+ *
>-+ * @section ffmpeg_versioning Versioning and compatibility
>-+ *
>-+ * Each of the FFmpeg libraries contains a version.h header, which defines a
>-+ * major, minor and micro version number with the
>-+ * <em>LIBRARYNAME_VERSION_{MAJOR,MINOR,MICRO}</em> macros. The major version
>-+ * number is incremented with backward incompatible changes - e.g. removing
>-+ * parts of the public API, reordering public struct members, etc. The minor
>-+ * version number is incremented for backward compatible API changes or major
>-+ * new features - e.g. adding a new public function or a new decoder. The micro
>-+ * version number is incremented for smaller changes that a calling program
>-+ * might still want to check for - e.g. changing behavior in a previously
>-+ * unspecified situation.
>-+ *
>-+ * FFmpeg guarantees backward API and ABI compatibility for each library as long
>-+ * as its major version number is unchanged. This means that no public symbols
>-+ * will be removed or renamed. Types and names of the public struct members and
>-+ * values of public macros and enums will remain the same (unless they were
>-+ * explicitly declared as not part of the public API). Documented behavior will
>-+ * not change.
>-+ *
>-+ * In other words, any correct program that works with a given FFmpeg snapshot
>-+ * should work just as well without any changes with any later snapshot with the
>-+ * same major versions. This applies to both rebuilding the program against new
>-+ * FFmpeg versions or to replacing the dynamic FFmpeg libraries that a program
>-+ * links against.
>-+ *
>-+ * However, new public symbols may be added and new members may be appended to
>-+ * public structs whose size is not part of public ABI (most public structs in
>-+ * FFmpeg). New macros and enum values may be added. Behavior in undocumented
>-+ * situations may change slightly (and be documented). All those are accompanied
>-+ * by an entry in doc/APIchanges and incrementing either the minor or micro
>-+ * version number.

>-+ * AVBuffer is an API for reference-counted data buffers.
>-+ *
>-+ * There are two core objects in this API -- AVBuffer and AVBufferRef. AVBuffer
>-+ * represents the data buffer itself; it is opaque and not meant to be accessed
>-+ * by the caller directly, but only through AVBufferRef. However, the caller may
>-+ * e.g. compare two AVBuffer pointers to check whether two different references
>-+ * are describing the same data buffer. AVBufferRef represents a single
>-+ * reference to an AVBuffer and it is the object that may be manipulated by the
>-+ * caller directly.
>-+ *
>-+ * There are two functions provided for creating a new AVBuffer with a single
>-+ * reference -- av_buffer_alloc() to just allocate a new buffer, and
>-+ * av_buffer_create() to wrap an existing array in an AVBuffer. From an existing
>-+ * reference, additional references may be created with av_buffer_ref().
>-+ * Use av_buffer_unref() to free a reference (this will automatically free the
>-+ * data once all the references are freed).
>-+ *
>-+ * The convention throughout this API and the rest of FFmpeg is such that the
>-+ * buffer is considered writable if there exists only one reference to it (and
>-+ * it has not been marked as read-only). The av_buffer_is_writable() function is
>-+ * provided to check whether this is true and av_buffer_make_writable() will
>-+ * automatically create a new writable buffer when necessary.
>-+ * Of course nothing prevents the calling code from violating this convention,
>-+ * however that is safe only when all the existing references are under its
>-+ * control.
>-+ *
>-+ * @note Referencing and unreferencing the buffers is thread-safe and thus
>-+ * may be done from multiple threads simultaneously without any need for
>-+ * additional locking.
>-+ *
>-+ * @note Two different references to the same buffer can point to different
>-+ * parts of the buffer (i.e. their AVBufferRef.data will not be equal).

>-+ * Utilities to make an array grow when needed.
>-+ *
>-+ * Sometimes, the programmer would want to have an array that can grow when
>-+ * needed. The libavutil dynamic array utilities fill that need.
>-+ *
>-+ * libavutil supports two systems of appending elements onto a dynamically
>-+ * allocated array, the first one storing the pointer to the value in the
>-+ * array, and the second storing the value directly. In both systems, the
>-+ * caller is responsible for maintaining a variable containing the length of
>-+ * the array, as well as freeing of the array after use.
>-+ *
>-+ * The first system stores pointers to values in a block of dynamically
>-+ * allocated memory. Since only pointers are stored, the function does not need
>-+ * to know the size of the type. Both av_dynarray_add() and
>-+ * av_dynarray_add_nofree() implement this system.
>-+ *
>-+ * @code
>-+ * type **array = NULL; //< an array of pointers to values
>-+ * int    nb    = 0;    //< a variable to keep track of the length of the array
>-+ *
>-+ * type to_be_added  = ...;
>-+ * type to_be_added2 = ...;
>-+ *
>-+ * av_dynarray_add(&array, &nb, &to_be_added);

>-+ *
>-+ * av_dynarray_add(&array, &nb, &to_be_added2);

>-+ * When the pixel format is palettized RGB32 (AV_PIX_FMT_PAL8), the palettized
>-+ * image data is stored in AVFrame.data[0]. The palette is transported in
>-+ * AVFrame.data[1], is 1024 bytes long (256 4-byte entries) and is
>-+ * formatted the same as in AV_PIX_FMT_RGB32 described above (i.e., it is
>-+ * also endian-specific). Note also that the individual RGB32 palette
>-+ * components stored in AVFrame.data[1] should be in the range 0..255.
>-+ * This is important as many custom PAL8 video codecs that were designed
>-+ * to run on the IBM VGA graphics adapter use 6-bit palette components.
>-+ *
>-+ * @par
>-+ * For all the 8 bits per pixel formats, an RGB32 palette is in data[1] like

>-+ *   24-bit sample format even though it is a common raw audio data format.
>-+ *
>-+ * - The floating-point formats are based on full volume being in the range
>-+ *   [-1.0, 1.0]. Any values outside this range are beyond full volume level.
>-+ *
>-+ * - The data layout as used in av_samples_fill_arrays() and elsewhere in FFmpeg
>-+ *   (such as AVFrame in libavcodec) is as follows:
>-+ *
>-+ * @par
>-+ * For planar sample formats, each audio channel is in a separate data plane,
>-+ * and linesize is the buffer size, in bytes, for a single plane. All data
>-+ * planes must be the same size. For packed sample formats, only the first data
>-+ * plane is used, and samples for each channel are interleaved. In this case,
>-+ * linesize is the buffer size, in bytes, for the 1 plane.
