 /**
  * 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.
