Not able to use H264 (video/avc) Encoder on Intel x86 device, Android 4.2.2

Question

I intend to encode raw YUV Data to H264 data for which I'm using Android's MediaCodec interface. Below is the snippet I have in place for the same:

MediaCodec mEncoder = MediaCodec.createEncoderByType("video/avc");

MediaFormat mVideoFormat = MediaFormat.createVideoFormat("video/avc", 640 , 480);
mVideoFormat.setInteger(MediaFormat.KEY_COLOR_FORMAT, CodecCapabilities.COLOR_FormatYUV420SemiPlanar);
mVideoFormat.setInteger(MediaFormat.KEY_BIT_RATE, 64000);
mVideoFormat.setInteger(MediaFormat.KEY_FRAME_RATE, 24);
mVideoFormat.setInteger(MediaFormat.KEY_I_FRAME_INTERVAL, 5);
mVideoFormat.setInteger(MediaFormat.KEY_AAC_PROFILE, MediaCodecInfo.CodecProfileLevel.AVCProfileBaseline);

mEncoder.configure(mVideoFormat, null, null, MediaCodec.CONFIGURE_FLAG_ENCODE);
mEncoder.start();
ByteBuffer[] mInputVideoBuffers = mEncoder.getInputBuffers();
ByteBuffer[] mOutputVideoBuffers = mEncoder.getOutputBuffers();

Although it works well on ARM devices , it fails on Intel x86 device I have (Samsung Tab 3) with below message:

E/ACodec(21756): [OMX.Intel.VideoEncoder.AVC] ERROR(0x80001001)

E/MediaCodec(21756): Codec reported an error. (omx error 0x80001001, internalError -2147483648)

Any help on this would be useful.

Answer 1

Found the fix for the issue. I did not release the Codec before creating another one . Multiple instances of Encoder is not permissible on Samsung Tab 3 running on Intel x86 device. This behaviour is pretty inconsistent across android devices; taking into account other devices on which I've had tested my code.

Answer 2

The code shown won't work on some ARM devices. COLOR_FormatYUV420SemiPlanar isn't supported everywhere.

You need to detect the set of available color formats at runtime. See the isRecognizedFormat() method in EncodeDecodeTest . To pass CTS, the device must allow one of those formats. There's five listed, but really there's only two (planar and semi-planar), and they're not radically different.

Answer 3

For Intel Devices Encoder.getOutput is Crashing , Created a media format and directly supplied to the encoder

MediaFormat mVideoFormat = MediaFormat.createVideoFormat("video/avc", 640 , 480);
mVideoFormat.setInteger(MediaFormat.KEY_COLOR_FORMAT, MediaCodecInfo.CodecCapabilities.COLOR_FormatSurface);
mVideoFormat.setInteger(MediaFormat.KEY_BIT_RATE, 64000);
mVideoFormat.setInteger(MediaFormat.KEY_FRAME_RATE, 24);
mVideoFormat.setInteger(MediaFormat.KEY_I_FRAME_INTERVAL, 5);

mTrackIndex = mMuxer.addTrack(mVideoFormat );
