FrameGrabber When reading a frame, the audio encoded in G722 format cannot be read

[water-rookie]

When the frame catcher reads the frame, it cannot read the audio in G722 format. Instead, the audio format obtained is MP2

[saudet]

Try to set the format by calling setFormat() before calling start(). There is also setAudioCodec() if what you want to set is the codec instead.

[water-rookie]

Set the audio decoder to G.722, but it is invalid, still can't get the audio information

Please provide the code you are using and the error message you are getting.

Please also try to call setFormat() to set the format to the correct value.

[water-rookie]

I set format to mpeg and the result is still the same

[water-rookie]

        FFmpegFrameGrabber grabber = new FFmpegFrameGrabber(inputFile);
        grabber.setAudioCodec(avcodec.AV_CODEC_ID_ADPCM_G722);
        grabber.setVideoCodec(avcodec.AV_CODEC_ID_H264);
        grabber.setOption("loglevel", "debug");
        grabber.setFormat("mpeg");
        grabber.start();
        log.info("imageWidth:" + grabber.getImageWidth());
        log.info("audio_c: " + grabber.getAudioCodecName());

[saudet]

Calling setAudioCodecName() instead of setAudioCodec() might work better?

[water-rookie]

Is audioCodecName set to G722?

[water-rookie]

grabber.setAudioCodecName("ADPCM_G722");

[water-rookie]

Still can't

[water-rookie]

[water-rookie]

Audio is still identified as Mp2

[saudet]

It's probably grabber.setAudioCodecName("g722"); before calling start(). Check the log for any error messages
