我在android中使用MediaCodec低级Api来解​​码从IP CAMERA收到的h264原始流.来自IP摄像机的原始流,在TCP/IP连接上接收.

要解码流,我的代码是:

@Override
protected void onCreate(Bundle savedInstanceState) {

 MediaCodec mCodecc;
 MediaFormat mFormat;
 BufferInfo mInfo;
 ByteBuffer[] inputBuffers ;
 ByteBuffer[] outputBuffers ;

}
protected void Init_Codec()
{
  mCodecc = MediaCodec.createDecoderByType("video/avc");
  mFormat =  MediaFormat.createVideoFormat("video/avc", width, height);

  mInfo = new BufferInfo();
mFormat.setInteger(MediaFormat.KEY_COLOR_FORMAT,MediaCodecInfo.CodecCapabilities.COLOR_FormatYUV420Planar);
  mCodecc.configure(mFormat, holder.getSurface(), null,0);
}

protected void Start_Codec()
{
  mCodecc.start();          
  inputBuffers = mCodecc.getInputBuffers();
  outputBuffers = mCodecc.getOutputBuffers();
}

private void OnRawStreamReceived(final ByteBuffer buffer)
{

 mHandler.postAtFrontOfQueue(new Runnable() {

@Override
public void run()
{
       int inIndex = mCodecc.dequeueInputBuffer(10000);
   if(inIndex>=0)
     {
    inputBuffers[inIndex] = buffer;
    mCodecc.queueInputBuffer(inIndex, 0,buffer.limit(),System.currentTimeMillis(), …
