29	/**
30	* The following API around MediaCodec and MediaFormat is based on the
31	* NDK one provided by Google since Android 5.0.
32	*
33	* Differences from the NDK API:
34	*
35	* Buffers returned by ff_AMediaFormat_toString and ff_AMediaFormat_getString
36	* are newly allocated buffer and must be freed by the user after use.
37	*
38	* The MediaCrypto API is not implemented.
39	*
40	* ff_AMediaCodec_infoTryAgainLater, ff_AMediaCodec_infoOutputBuffersChanged,
41	* ff_AMediaCodec_infoOutputFormatChanged, ff_AMediaCodec_cleanOutputBuffers
42	* ff_AMediaCodec_getName and ff_AMediaCodec_getBufferFlagEndOfStream are not
43	* part of the original NDK API and are convenience functions to hide JNI
44	* implementation.
45	*
46	* The API around MediaCodecList is not part of the NDK (and is lacking as
47	* we still need to retrieve the codec name to work around faulty decoders
48	* and encoders).
49	*
50	* For documentation, please refers to NdkMediaCodec.h NdkMediaFormat.h and
51	* http://developer.android.com/reference/android/media/MediaCodec.html.
