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

format
Filter the word “frame” indicates either a video frame or a group of audio as stored in an AVFrame structure Format for each input and each output the list of supported formats For video that means pixel format For audio that means channel sample format(the sample packing is implied by the sample format) and sample rate. The lists are not just lists
