Could not open audio codec #291

After I call start() on a recorder, I get the following error:

org.bytedeco.javacv.FrameRecorder$Exception: avcodec_open2() error -22: Could not open audio codec.

This happens with a video having the following info:

Stream #0:0: Video: mjpeg (MJPG / 0x47504A4D), yuvj422p(pc, bt470bg/unknown/unknown), 640x480, 9732 kb/s, 30 fps, 30 tbr, 30 tbn, 30 tbc
Stream #0:1: Audio: pcm_u8 ([1][0][0][0] / 0x0001), 11024 Hz, 1 channels, u8, 88 kb/s

Other media content was processed normally so far.
I've tried to not set audio codec as was suggested here: #72, unfortunately this didn't help. Could you give me any idea on how to fix it? Thank you in advance.

What happens if you call setAudioChannels(0) before calling start()?

Could you enable debug messages in the log and see if it gives us any clues as to why the audio codec doesn't want to open?

If I setAudioChannels(0) before calling start() I will have the following output:

And what does it look like when you do setAudioChannels(1)?

It outputs the following in that case (setAudioChannels(1)):

It explains quite clearly why it fails:

[aac @ 0x7fbbc3345a00] Specified sample rate 11024 is not supported

So, try to use a different sample rate or another codec that supports that sample rate.
