* avcodec/codec_internal: Add macro to set AVCodec.long_nameAndreas Rheinhardt2022-09-031-2/+2
| | | | | | | | 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>
* avcodec/internal: Move ff_get_buffer() to decode.hAndreas Rheinhardt2022-08-271-2/+1
| | | | | | | | | 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>
* avcodec: Make init-threadsafety the defaultAndreas Rheinhardt2022-07-181-4/+2
| | | | | | | | | | | 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.

* avcodec/codec_internal: Use union for FFCodec decode/encode callbacksAndreas Rheinhardt2022-04-051-2/+2
| | | | | | | | | | | 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.

* avcodec/codec_internal: Make FFCodec.decode use AVFrame*Andreas Rheinhardt2022-04-051-2/+1
| | | | | | | | 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>
* avcodec/codec_internal: Add FFCodec, hide internal part of AVCodecAndreas Rheinhardt2022-03-211-12/+12
| | | | | | | | | | | | | | | | 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.

* avcodec/internal: Move FF_CODEC_CAP_* to a new header codec_internal.hAndreas Rheinhardt2022-03-211-0/+1
| | | | | | | | | | 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>

| | | | | | | | | | 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.
