* 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/mpegvideoenc: Remove ineffective optionsAndreas Rheinhardt2022-05-24
| | | | | | | | | | | | | | | | This commit removes the ineffective FF_MPV_DEPRECATED_ options, namely mpeg_quant (this is only an option for MPEG-4), a53cc (this is only an option for MPEG-2), force_duplicated_matrix (applies only to MJPEG) and b_strategy, b_sensitivity and brd_scale (these options only make sense for encoders supporting B-frames, which currently means the MPEG-1/2 and MPEG-4 encoders). Given that these options never changed the outcome of encoding, they are removed at once. Notice that the options for the encoders for which it made sense are not affected by this.

* avcodec/mjpegenc: Remove pointless motion-estimation optionsAndreas Rheinhardt2022-05-24
| | | | | | | | (M)JPEG does not use motion estimation/motion vectors at all. These options therefore don't affect the output at all. So remove them. 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/mpegvideo: Make new_picture an ordinary AVFrameAndreas Rheinhardt2022-04-01
| | | | | | | | | It is currently a "Picture", an mpegvideo-specific type that has a lot of baggage, all of which is unnecessary for new_picture, because only its embedded AVFrame is ever used. So just use an ordinary AVFrame. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/mpegvideo: Remove strict_std_compliance from MpegEncContextAndreas Rheinhardt2022-04-01
| | | | | | It just duplicates AVCodecContext.strict_std_compliance. 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>
* libavcodec: Split version.hMartin Storsjö2022-03-16
| | | | | | | | | | | | | | This avoids including version.h in all source files, avoiding unnecessary rebuilds when the version number is bumped. Only version_major.h is included by the main header, which defines availability of e.g. FF_API_* macros, and which is bumped much less often. This isn't done for libavutil/version.h, because that header needs to be included essentially everywhere due to LIBAVUTIL_VERSION_INT being used wherever an AVClass is constructed.

* 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/mpeg4video: Make initializing RLTable thread-safeAndreas Rheinhardt2021-04-27
| | | | | | | | | | | Up until now the RLTable ff_mpeg4_rl_intra was initialized by both mpeg4 decoder and encoder (except the VLCs that are only used by the decoder). This is an obstacle to making these codecs init-threadsafe, so move initializing this to a single function that is guarded by a dedicated AVOnce.

* avcodec/mpegvideo: Deprecate bframe opts for encoders not supporting themAndreas Rheinhardt2021-04-10
| | | | | | | | | | | MPEG-1/2/4 are the only mpegvideo based encoders that support bframes; yet even the encoders not supporting bframes have options that only make sense for an encoder that supports bframes; setting any of these options for such an encoder has no impact on the encoded outcome (but setting b_strategy to two slows down encoding considerably). So deprecate these options. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/mpegvideo: Deprecate mpeg_quant option for codecs != MPEG-4Andreas Rheinhardt2021-04-10
| | | | | | | | | | | | | | mpeg_quant may only be set for MPEG-4 and MPEG-2, yet for the latter it is no option as the code acts as if it were always set. So deprecate the option for all codecs for which it makes no sense. Furthermore, given that the code already errors out if the option is set for a codec that doesn't support it we can restrict the range of the option for all these codecs without breaking something. This means that the checks for whether mpeg_quant is set for these codecs can be removed as soon as AVCodecContext.mpeg_quant is removed.
