Function Documentation

int ff_AMediaCodecProfile_getProfileFromAVCodecContext ( AVCodecContext * avctx )

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 retreive 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.
