James Almer	dc7bd7c5a5	avcodec: use the new AVFrame key_frame flag in all decoders and encoders Signed-off-by: James Almer <jamrial@gmail.com>	2 years ago
Andreas Rheinhardt	48286d4d98	avcodec/codec_internal: Add macro to set AVCodec.long_name It reduces typing: Before this patch, there were 105 codecs whose long_name-definition exceeded the 80 char line length limit. Now there are only nine of them. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	2 years ago
Andreas Rheinhardt	66b691f99f	avcodec/internal: Move ff_get_buffer() to decode.h Only used by decoders (encoders have ff_encode_alloc_frame()). Also clean up the other headers a bit while removing now redundant internal.h inclusions. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	2 years ago
Andreas Rheinhardt	4243da4ff4	avcodec/codec_internal: Use union for FFCodec decode/encode callbacks This is possible, because every given FFCodec has to implement exactly one of these. Doing so decreases sizeof(FFCodec) and therefore decreases the size of the binary. Notice that in case of position-independent code the decrease is in .data.rel.ro, so that this translates to decreased memory consumption.

Andreas Rheinhardt	ce7dbd0481	avcodec/codec_internal: Make FFCodec.decode use AVFrame* This increases type-safety by avoiding conversions from/through void. It also avoids the boilerplate "AVFrame frame = data;" line for non-subtitle decoders. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	3 years ago
Andreas Rheinhardt	20f9727018	avcodec/codec_internal: Add FFCodec, hide internal part of AVCodec Up until now, codec.h contains both public and private parts of AVCodec. This exposes the internals of AVCodec to users and leads them into the temptation of actually using them and forces us to forward-declare structures and types that users can't use at all. This commit changes this by adding a new structure FFCodec to codec_internal.h that extends AVCodec, i.e. contains the public AVCodec as first member; the private fields of AVCodec are moved to this structure, leaving codec.h clean.

Andreas Rheinhardt	a247ac640d	avcodec: Constify AVCodecs Given that the AVCodec.next pointer has now been removed, most of the AVCodecs are not modified at all any more and can therefore be made const (as this patch does); the only exceptions are the very few codecs for external libraries that have a init_static_data callback.
