Anton Khirnov	7693ba0a0e	hevc: export stream parameters from extradata This allows the callers to have a hint of the probable stream parameters without actually decoding anything.	10 years ago
Anton Khirnov	1ae7afd256	hevc: split out setting AVCodecContext parameters Additionally always set the software pixel format, so it's available even if ff_get_format() is not called later. This will be useful for exporting stream parameters from init().	10 years ago
Peter Meerwald	eea769df32	hevc: Use generic av_clip function, not C implementation hevc seems to be the only place where the C implementation of the av_clip function is explicitly selected, precluding platform-specific optimizations Signed-off-by: Peter Meerwald <pmeerw@pmeerw.net> Signed-off-by: Anton Khirnov <anton@khirnov.net>	10 years ago

Vittorio Giovara	b1b1a7370e	display: fix order of operands CC: libav-stable@libav.org Bug-Id: CID 1238828 / CID 1238832	10 years ago
Anton Khirnov	7ea1b3472a	lavc: deprecate the use of AVCodecContext.time_base for decoding When decoding, this field holds the inverse of the framerate that can be written in the headers for some codecs. Using a field called 'time_base' for this is very misleading, as there are no timestamps associated with it. Furthermore, this field is used for a very different purpose during encoding. Add a new field, called 'framerate', to replace the use of time_base for decoding.	10 years ago
