* avcodec: Make init-threadsafety the defaultAndreas Rheinhardt2022-07-18
| | | | | | | | | | | 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 Rheinhardt2022-04-05
| | | | | | | | | | | 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 Rheinhardt2022-04-05
| | | | | | | | 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 Rheinhardt2022-03-21
| | | | | | | | | | | | | | | | 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 Rheinhardt2022-03-21
| | | | | | | | | | 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>

* avcodec/thread: Don't use ThreadFrame when unnecessaryAndreas Rheinhardt2022-02-09
| | | | | | | | | | | | | | | | | | | | | | | The majority of frame-threaded decoders (mainly the intra-only) need exactly one part of ThreadFrame: The AVFrame. They don't need the owners nor the progress, yet they had to use it because ff_thread_(get|release)_buffer() requires it. This commit changes this and makes these functions work with ordinary AVFrames; the decoders that need the extra fields for progress use ff_thread_(get|release)_ext_buffer() which work exactly as ff_thread_(get|release)_buffer() used to do. This also avoids some unnecessary allocations of progress AVBuffers, namely for H.264 and HEVC film grain frames: These frames are not used for synchronization and therefore don't need a ThreadFrame. Also move the ThreadFrame structure as well as ff_thread_ref_frame() to threadframe.h, the header for frame-threaded decoders with inter-frame dependencies.

| | | | | | | | | | 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.

* avcodec: set AV_CODEC_CAP_CHANNEL_CONF on decoders which set their own channelsHendrik Leppkes2020-12-10
| | | | | | | | | | | | The decoders in this set either have a fixed channel count, or read it from the bitstream, and thus do not require the channel count as external information. Fixes various regressions since 81503ac58a763a36b1f57264013b1e76acb62b68, which requires a valid channel count for decoders which do not set this capability.

* pthread_frame: merge the functionality for normal decoder init and ↵Anton Khirnov2020-04-10
| | | | | | | | | | | | | | | | init_thread_copy The current design, where - proper init is called for the first per-thread context - first thread's private data is copied into private data for all the other threads - a "fixup" function is called for all the other threads to e.g. allocate dynamically allocated data is very fragile and hard to follow, so it is abandoned. Instead, the same init function is used to init each per-thread context. Where necessary, AVCodecInternal.is_copy can be used to differentiate between the first thread and the other ones (e.g. for decoding the extradata just once).
* avformat/matroskadec: avcodec/tta: Set extradata_size to 22Andreas Rheinhardt2019-12-04
| | | | | | | | | | | | | | | Up until c4e0e314, the seek table has been included in the tta extradata, so that the size of said extradata was 22 (the size of a TTA1 header) + 4 * number of frames. The decoder rejected anything below a size of 30 and so the Matroska demuxer exported 30 byte long extradata, of which only 18 were set (it ignores a CRC-32 and simply leaves it at 0). But this is unnecessary since said commit, so reduce the size to 22. Furthermore, replace 30 by 22 in a comment about the extradata size in libavcodec/tta.c.
