/**
* The following API around MediaCodec and MediaFormat is based on the
* NDK one provided by Google since Android 5.0.
*
* Differences from the NDK API:
*
* Buffers returned by ff_AMediaFormat_toString and ff_AMediaFormat_getString
* are newly allocated buffer and must be freed by the user after use.
*
* The MediaCrypto API is not implemented.
*
* ff_AMediaCodec_infoTryAgainLater, ff_AMediaCodec_infoOutputBuffersChanged,
* ff_AMediaCodec_infoOutputFormatChanged, ff_AMediaCodec_cleanOutputBuffers
* ff_AMediaCodec_getName and ff_AMediaCodec_getBufferFlagEndOfStream are not
* part of the original NDK API and are convenience functions to hide JNI
* implementation.
*
* The API around MediaCodecList is not part of the NDK (and is lacking as
* we still need to retrieve the codec name to work around faulty decoders
* and encoders).
*
* For documentation, please refers to NdkMediaCodec.h NdkMediaFormat.h and
* http://developer.android.com/reference/android/media/MediaCodec.html.
