# Codec values (codec_video_main, codec_video_content, codec_audio):
# it'll force the specified codec.
# Put the 'ANY' value to prevent forcing a specific codec without the _priority options.
# For the 'ANY' option, there's a trio of optional configuration where you are
# able to specify the priority codec to force in a lenient way (codec_*_priority).
# If codec_*_priority is undefined or not found in the media description,
# no specific codec will be forced (base ANY behaviour).
# If the priority codec is found in the media description, any codec
# that doesn't match it will be filtered out (ie it will act as if the priority
# codec was forced).
# If you wanna add other codecs (e.g.: VP9)
# add it to the list with its specifiers. If the codec isn't in the list,
# it'll default to the specifier values in codec_*_priority OR VP8,
# but still force the entered codec option.
# P.S.: _video_main refers to webcam/main video content, _video_content refers to
# screenshare/content:slides streams.
