># PROVIDE: webcamd
># REQUIRE: DAEMON LOGIN
># KEYWORD: shutdown
>#
># It is recommended to configure webcamd in the following way:
>#
># webcamd_enable="YES"
># webcamd_devices_0_name=<put here the single product name of your USB devices, as printed in the 2nd column of 'usbconfig' command. Do not repeat it.>
># webcamd_devices_{1,2,3...99}_name=<put in seperate variables the name of 2nd, 3rd *types* of connected USB device. Only if you have a mixture of different model types>
>#
># Advanced settings:
>#
># webcamd_startup_delay=<if multiple devices, the number of seconds to wait before launching the next instance of webcamd>
># webcamd_user=<the user to run webcamd as>
># webcamd_group=<the group to run webcamd as>
># webcamd_flags=<set additional global webcamd flags, applied on all instances>
>#
># 2 other ways:
>#
># webcamd_devices=<a list of USB device numbers, such as 'ugen2.2' for webcamd to attach to>
># webcamd_instance_{0,1,2,3}_flags=<to set manually each individual spawned instances, put here it's webcamd flags>
>#
># You may use any of 3 ways in combination. Pick the right tool for right job.
># However do not use more than one method for each physical device.
>#
># Examples:
># sysrc webcamd_enable=YES
># sysrc webcamd_startup_delay=2
>#
># Method 1:
># sysrc "webcamd_devices_0_name=Acer Crystal Eye webcam SuYin"
># sysrc "webcamd_devices_1_name=SCEH-0036 SONY"
>#
># Method 2:
># sysrc "webcamd_devices=ugen2.2, 7.3"
>#
># Method 3:
># sysrc webcamd_startup_delay=0
># sysrc "webcamd_instance_0_flags=-L 127.0.0.1:5100:-1"
># sysrc "webcamd_instance_1_flags=-d ugen7.4 -v 2 -i 1 -m v4l2-dev.hflip=1"
