38 Rename PixelFormat to AVPixelFormat and all PIX_FMT_* to AV_PIX_FMT_*.
39 To provide backwards compatibility, PixelFormat is now #defined as
40 AVPixelFormat.
41 Note that this can break user code that includes pixfmt.h and uses the
42 'PixelFormat' identifier. Such code should either #undef PixelFormat
43 or stop using the PixelFormat name.

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