AK
192012-08-xx - xxxxxxx - lavc 54.25 - avcodec.h
20 Rename CodecID to AVCodecID and all CODEC_ID_* to AV_CODEC_ID_*.
2ff67c90
AK
21 To provide backwards compatibility, CodecID is now #defined as AVCodecID.
22 Note that this can break user code that includes avcodec.h and uses the
23 'CodecID' identifier. Such code should either #undef CodecID or stop using the
24 CodecID name.

84 For audio formats with fixed frame size, the last frame
85 no longer needs to be padded with silence, libavcodec
86 will handle this internally (effectively all encoders
87 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).
