Hello. Wnen I build firefox from ports with ffmpeg I can't play videos (HTML5, youtube) on higher speeds (1,25 ... 2) video and sound starts jitter stutter lag. So I have to use Firefox-esr which doesn't have such problems. $ uname -r 11.0-STABLE Regards, Sergey.
Created attachment 178849 [details] bsd.gecko.mk.diff It's good that you've opened a bug for this. The problem appears to be independent of the audio output used. It happens with ALSA and SNDIO. With PULSEAUDIO its less pronounced but you still hear clicking sounds where there should be none. On OpenBSD this does not happen. One difference between the FreeBSD port and the OpenBSD port is that OpenBSD does not use the system libsoundtouch, but uses the bundled one instead. It seems to be a slightly different version than audio/soundtouch. Removing the --with-system-soundtouch flag from bsd.gecko.mk makes it work correctly on FreeBSD. I've only tested www/firefox with SNDIO=on though.
(In reply to Tobias Kortkamp from comment #1) Hi Tobias. Is it possible to move the patch upstream so that we could use the fixed version of Firefox? Thanx for your great support! Sergey P.
(In reply to Sergey from comment #2) We can hope that a committer agrees with me and commits the patch or a similar fix to the ports tree. Can you confirm that it fixes the problem?
(In reply to Tobias Kortkamp from comment #3) Hi Tobias. Everything works like a charm! :) Don't we have to remove the following build dependency from a Makefile also: soundtouch>=1.9.0:audio/soundtouch \ ? As a bonus we've got ridden of additional useless (in this case) soundtouch dependency. I've switched over to Firefox 50.1.0 with SNDIO now and use it without any problems, Thanx! Sergey P.
(In reply to Tobias Kortkamp from comment #3) I was a bit hurry with my conclusions. I observe a strange effects now when the same video on youtube at first starts to blink and jitter (the sound meanwhile flows normally), and after reloading the page or stopping and starting it again it goes fine. My default video quility is - 'High definition MP4'. More to say, I've tried 5-8 times and only twice got a glitch. So the problem is unstable. Best regards, Sergey.
Comment on attachment 178849 [details] bsd.gecko.mk.diff > -.if exists(${FILESDIR}/patch-z-bug517422) > -soundtouch_LIB_DEPENDS= libSoundTouch.so:audio/soundtouch > -soundtouch_MOZ_OPTIONS= --with-system-soundtouch > -.endif Add "-soundtouch" to USE_MOZILLA in www/firefox/Makefile or drop "soundtouch" in _ALL_DEPENDS in Mk/bsd.gecko.mk if the issue affects all Gecko versions. However, I'd prefer if this was bisected first. Depending on the results one can fix soundtouch usage in Gecko, add a workaround to audio/soundtouch port or drop system soundtouch support completely.
(In reply to Tobias Kortkamp from comment #3) For example this clip: https://www.youtube.com/watch?v=eXS_OC1UQG8 after 10 mins af watching started to blink again, repeating the same videofragment over and over again... Just another quietion, Tobias, do i have to tune following parameters in /etc/sysctl.conf file: hw.snd.maxautovchans=16 dev.pcm.0.play.vchans=1 dev.pcm.0.rec.vchans=1 Maybe set them to 4 or 8? Because sndiod use this option -c 0:7.
