My problem is: I have a pcm mic and I plugged in to the front panel. The default Ubuntu sound-recorder can capture it, but ffmpeg not. I'm not sure I tried the correct dev, but I tried a lot ->
/dev/audio
/dev/mixer
/dev/snd/pcmC0D0c
/dev/snd/pcmC0D0p
/dev/snd/pcmC0D1p
But all of them makes an error: unknown format (with this way: ffmpeg -i /dev/mixer test.wav)
Maybe I missed a codec param, or what?
The sound-recorder set to:
input: record (and record1 is also working)
codec: speex (lossy)
