Я установил ffmpeg из исходного кода с помощью --enable-libmp3lame.
Теперь, когда я запускаю ffmpeg с:
sudo ffserver -f ffserver.conf & ffmpeg -s 320x240 -f video4linux2 -i /dev/video0 http://localhost:7070/feed1.ffm Я получаю этот вывод:

Your ffmpeg command only outputs video. You need to generate a blank audio:
ffmpeg -s 320x240 -f video4linux2 -i /dev/video0 -f lavfi -i aevalsrc=0 \ -c:a libmp3lame http://localhost:7070/feed1.ffm Another weird thing in your command line is that you don't encode video. I assume you don't want raw YUV video to be streames, right?
