* Revert "all: Don't set AVClass.item_name to its default value"Anton Khirnov2024-01-20
| | | | | | | Some callers assume that item_name is always set, so this may be considered an API break. This reverts commit 0c6203c97a99f69dbaa6e4011d48c331e1111f5e.
* all: Don't set AVClass.item_name to its default valueAndreas Rheinhardt2023-12-22
| | | | | | | | Unnecessary since acf63d5350adeae551d412db699f8ca03f7e76b9; also avoids relocations. Reviewed-by: Anton Khirnov <anton@khirnov.net> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/codec_internal: Add macro to set AVCodec.long_nameAndreas Rheinhardt2022-09-03
| | | | | | | | 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: 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/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/ituh263enc: Make static initializations thread-safeAndreas Rheinhardt2021-04-27
| | | | | | | | | | | | This already makes several encoders (namely FLV, H.263, H.263+ and RealVideo 1.0 and 2.0 and SVQ1) that use this init-threadsafe. It also makes the Snow encoder init-threadsafe; it was already marked as such since commit d49210788b0836d56dd872d517fe73f83b080101, because it was thought to be harmless if one and the same object was initialized by multiple threads at the same time.

* avcodec/h263data, ituh263*: Make initializing RL inter table thread-safeAndreas Rheinhardt2021-01-25
| | | | | | | | | | | | Up until now, ff_h263_rl_inter was initialized by both ituh263dec and ituh263enc; this is an obstacle in making the codecs that use this code init-threadsafe. This obstacle is eliminated by only initializing this RLTable from a single place that is guarded by a dedicated AVOnce.

* put_bits: make avpriv_align_put_bits() inlineAnton Khirnov2020-10-28
