avcodec_find_decoder() error: Unsupported audio format or codec not found: 0.

How to solve this problem

[saudet]

It looks like you're trying to open AV_CODEC_ID_NONE, which doesn't exist. You'll need to pick another from this list: https://github.com/bytedeco/javacpp-presets/blob/master/ffmpeg/src/gen/java/org/bytedeco/ffmpeg/global/avcodec.java#L67

This error occurred when capturing a video file without audio

[saudet]

That looks like a corrupted file. What happens if you try to use it with the ffmpeg or ffplay program?

[IT-LiuGuang]

The file is normal, a camera that does not support audio, the saved video can generate this kind of file

[saudet]

Ok, but if the ffmpeg program cannot process that file either, please report this bug upstream: http://ffmpeg.org/bugreports.html

[IT-LiuGuang]

Thank you very much for your answer

[saudet]

If it works fine with the ffmpeg program though, it means this is an issue with JavaCV, so please try it with the ffmpeg program and let me know! Thanks

[IT-LiuGuang]

Use the ffmpeg command to push the stream, and then use VLC to play with no problem

[IT-LiuGuang]

See the method you proposed in #1184 , add grabber.setAudioStream(Integer.MAX_VALUE)

[IT-LiuGuang]

No errors were reported after joining, and the program runs normally

[saudet]

Ok, could you attach here a sample video file that fails like this?

[IT-LiuGuang]

Sorry, I can’t provide it, I am using a camera RTSP, I don’t have a video source
