Currently using version 2.2.2 beta.
I think the default audio mixer channel layout is 8 channels.
How can I change the audio channel layout to stereo for the ffmpeg producer for streaming rtmp?
Methods that I have tried but failed.
- config file (works for 2.1 and 1.7 but not 2.2)
<channel> <video-mode>720p2997</video-mode> <channel-layout>stereo</channel-layout> <consumers> </consumers> </channel>
- add ffmpeg options (-ac 2). ffmpeg consumer unitialized the stream.
Result of the stream’s audio is 7.1 channel and not stereo
Input #0, flv, from ‘rtmp://71.xxx’:
encoder : Lavf58.17.101

[aac @ 0000000000659f00] Assuming an incorrectly encoded 7.1 channel layout instead of a spec-compliant 7.1(wide) layout, use -strict 1 to decode according to the specification instead.
Any help would be appreciated
