How To Use Android Mediacodec Encode Camera Data(yuv420sp)

Thank you for your focus! I want to use Android MediaCodec APIs to encode the video frame which aquired from Camera, unfortunately, I have not success to do that! I still not famil

Solution 1:

I have solved the problem.As follows：

privatesynchronizedvoidencode(byte[] data)
{
    inputBuffers = mMediaCodec.getInputBuffers();// here changes
    outputBuffers = mMediaCodec.getOutputBuffers();

    intinputBufferIndex= mMediaCodec.dequeueInputBuffer(-1);
    Log.i(TAG, "inputBufferIndex-->" + inputBufferIndex);
    //......

And next,you will find your encoded video color is not right, for more information,please go to here MediaCodec and Camera: colorspaces don't match

Solution 2:

The YUV420 formats output by the camera are incompatible with the formats accepted by the MediaCodec AVC encoder. In the best case, it's essentially NV12 vs. NV21 (U and V planes are reversed), requiring a manual reordering. In the worst case, as of Android 4.2, the encoder input format may be device-specific.

You're better off using MediaRecorder to connect the camera hardware to the encoder.

Update: It's now possible to pass the camera's Surface preview to MediaCodec, instead of using the YUV data in the ByteBuffer. This is faster and more portable. See the CameraToMpegTest sample here.
