Details

I guess something wrong relative to format change about "INFO_FORMAT_CHANGED" and "INFO_OUTPUT_BUFFERS_CHANGED".

For example:
If the INFO_FORMAT_CHANGED comes from mCodec->dequeueOutputBuffer in GetCodecOutputData(), then we call UpdateAudioInfo/UpdateVideoInfo. It might falls into an infinite loop because we call mCodec->dequeueOutputBuffer again and expect that we should receive a INFO_FORMAT_CHANGED, but the INFO_FORMAT_CHANGED had been received by previous mCodec->dequeueOutputBuffer in GetCodecOutputData().

I will try to find some testing file to verify the code path.
