Niklas Haas	61ffa23c2e	avcodec/codec_internal: add cap for ICC profile support Codecs that can read/write ICC profiles deserve a special capability so the common logic in encode.c/decode.c can decide whether or not there needs to be any special handling for ICC profiles. The motivation here is to be able to use it to decide whether or not an ICC profile needs to be generated in the encode path, but it might as well get added to decoders as well for purely informative reasons. It's not entirely clear to me whether the "thp" and "smvjpeg" variants of "mjpeg" should have this capability set or not, given that the code technically supports it but I somehow doubt these files may contain them. In either case, this cap is purely informative for decoders so it doesn't matter too much either way. It's also not entirely clear whether the "amv" encoder should signal ICC profile support, but again erring on the side of caution, we probably shouldn't be generating (and encoding!) ICC profiles for this type of media file. Signed-off-by: Niklas Haas <git@haasn.dev>	2 years ago
Andreas Rheinhardt	21b23ceab3	avcodec: Make init-threadsafety the default and remove FF_CODEC_CAP_INIT_THREADSAFE All our native codecs are already init-threadsafe (only wrappers for external libraries and hwaccels are typically not marked as init-threadsafe yet), so it is only natural for this to also be the default state.

Andreas Rheinhardt	6aad1204cc	avcodec: Add FF_CODEC_CAP_NOT_INIT_THREADSAFE This is in preparation of switching the default init-thread-safety to a codec being init-thread-safe. 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	fb59a42ef9	avcodec/codec_internal: Add FFCodec.decode_sub This increases type-safety by avoiding conversions from/through void. It also avoids the boilerplate "AVSubtitle sub = data;" line for subtitle decoders. Its only downside is that it increases sizeof(FFCodec), yet this can be more than offset lateron.

Andreas Rheinhardt	5aabb2596f	avcodec/codec_internal: Rename AVCodecDefault->FFCodecDefault This structure is no longer declared in a public header, so using an FF-prefix is more appropriate. 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	a688f3c13c	avcodec/internal: Move FF_CODEC_CAP_* to a new header codec_internal.h Also move FF_CODEC_TAGS_END as well as struct AVCodecDefault. This reduces the amount of files that have to include internal.h (which comes with quite a lot of indirect inclusions), as e.g. most encoders don't need it. It is furthemore in preparation for moving the private part of AVCodec out of the public codec.h. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	3 years ago
