Hi All,
I am trying to get RAW YV12 frames (from onPreviewFrame) and convert the
same the H.264, using MediaCodec class. So far i have not been able to
convert the H.264 successfully. The reason being not sure how to extract
the NAL (SPS and PPS ) info and add it to the Encoder. My sample code for
deque is as below.
final int TIMEOUT_USEC = 100;
byte idrFrameType = 0x65;
if (VERBOSE) Log.d(TAG, "drainEncoder(" + endOfStream + ")");
ByteBuffer[] outputBuffers = encoder.getOutputBuffers();
int outputBufferIndex = encoder.dequeueOutputBuffer(bufferInfo,0);
while (outputBufferIndex >= 0) {
ByteBuffer outputBuffer = outputBuffers[outputBufferIndex];
byte[] outData = new byte[bufferInfo.size];
outputBuffer.get(outData);
try {
stream.write(outData);
} catch (IOException e) {
e.printStackTrace();
}
Log.d("AvcEncoder", outData.length + " bytes written");
encoder.releaseOutputBuffer(outputBufferIndex, false);
outputBufferIndex = encoder.dequeueOutputBuffer(bufferInfo, 0);
}
I have even tried the INFO_OUTPUT_FORMAT_CHANGED but that didnt help
either. Currently i am writing the data to a file, but the big
picture is to stream to a server. When i try to play the save file
with the default android player it never plays.
Thanks,
Ankur.
