* 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: Add const to decoder packet data pointersAndreas Rheinhardt2022-07-09
| | | | | | | The packets given to decoder need not be writable, so it is best to access them via const uint8_t*. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* 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: Constify AVCodecsAndreas Rheinhardt2021-04-27
| | | | | | | | | | 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/pafvideo: Only clear frame when it was written toMichael Niedermayer2019-11-09
| | | | | | | | | | | This avoids unneeded operations and makes the code faster. Fixes: Timeout Fixes: 15724/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_PAF_VIDEO_fuzzer-5750842205929472 (12sec -> 9sec) Fixes: 17625/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_PAF_VIDEO_fuzzer-5640515311108096 (16sec -> 4sec) Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/projects/ffmpeg Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
* avcodec/decode: add a flags parameter to ff_reget_buffer()James Almer2019-09-04
| | | | | | | | | | Some decoders may not need a writable buffer in some specific cases, but only a reference to the existing buffer with updated frame properties instead, for the purpose of returning duplicate frames. For this, the FF_REGET_BUFFER_FLAG_READONLY flag is added, which will prevent potential allocations and buffer copies when they are not needed. Signed-off-by: James Almer <jamrial@gmail.com>
