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.
