rawAudioData

获取音频数据

对于某些需要获得音频原始数据的用户我们提供了OnAudioPCMListener接口，通过此接口上层用户可以获得PCM音频数据进行使用

public interface OnAudioPCMListener {
    /**
     * @param buffer        audio data
     * @param timestamp     time stamp
     * @param channels      the number of channels
     * @param samplerate    the number of samples in a single channel
     * @param fmt           the sample format 
                            
                            format:
                            0,          ///< unsigned 8 bits
                            1,         ///< signed 16 bits
                            2,         ///< signed 32 bits
                            3,         ///< float
                            4,         ///< double
                            5,         ///< unsigned 8 bits, planar
                            6,        ///< signed 16 bits, planar
                            7,        ///< signed 32 bits, planar
                            8,        ///< float, planar
                            9,        ///< double, planar
    **/

    void onAudioPCMAvailable(IMediaPlayer mp, ByteBuffer buffer, long timestamp, int channels, int samplerate, int fmt);
}

基本设置

必须在调用 prepareAsync 之前设置，开发者无需申请缓存，只需要注册相应的回调接口提供给播放器即可

使用示例

//[important]make sure it is called before "prepareAsync"
KSYMediaPlayer.OnAudioPCMListener AudioListener = new KSYMediaPlayer.OnAudioPCMListener() {
    @Override
    public void onAudioPCMAvailable(IMediaPlayer mp, ByteBuffer buffer, long timestamp, int channels, int samplerate, int fmt){
        Log.e(TAG, "onAudioPCMAvailable timestamp "+ timestamp: + " channels: "+ channels+ " samplerate: "+ samplerate + " fmt: "+ fmt);
        //user porcess
        //........
    }
};
ksyMediaPlayer.setOnAudioPCMAvailableListener(AudioListener);
