Description

Why do I get different frame contents after extracting frames from audio using JavaCV version 1.5.9 and version 1.5.11? The settings for FFmpegFrameRecorder are as follows:

FFmpegFrameRecorder recorder = new FFmpegFrameRecorder();
recorder.setAudioCodec(avcodec.AV_CODEC_ID_PCM_S16LE);
recorder.setAudioChannels(1);
recorder.setAudioQuality(0);
recorder.setSampleRate(11025);
recorder.setFormat("wav");
