如何从 Android 中的视频文件中分离音频 stream 比特率？

Question

I want to get audio bitrate from video file and save it. Is it possible to get audio track bitrate alone form video file using ffmpeg?
if possible then how to do it?...Any suggestion will be appreciated.

Maybe this would help you:

    @Override
    public void onProgress(String message) {

        Log.e("ryeure", "onProgress: ");


        String findWithinHorizon = new Scanner(message).findWithinHorizon(Pattern.compile(".?fltp,\\s([0-9]*)\\skb/s"), 0);

        Log.e("ryeure", "onProgress: findwithinhorizon---" + findWithinHorizon);


        if (findWithinHorizon != null) {
            String intValue = findWithinHorizon.replaceAll("[^0-9]", "");

            result_audioBitrate = Integer.parseInt(intValue) * 1000;
        }

    }

    @Override
    public void onFailure(String message) {

        Log.e("ryeure", "onFailure: onfailure--" + result_audioBitrate);


        audio_origin_bitrate.setText("Origin bitrate : " + result_audioBitrate + " kb/s");
        audio_new_bitrate.setText("New bitrate : " + result_audioBitrate + " kb/s");
    }
