* avcodec/avcodec: Remove AV_CODEC_FLAG2_DROP_FRAME_TIMECODEAndreas Rheinhardt2023-02-091-1/+0
| | | | | | | | | | It has been deprecated in 94d68a41fabb55dd8c7e59b88fe4a28a637d1e5f and can't be set via AVOptions. The only codecs that use it (the MPEG-1/2 encoders) have private options for this. So remove it.

* avcodec/mpeg12enc: Don't initialize unused parts of RLTableAndreas Rheinhardt2022-10-271-7/+10
| | | | | | | | | ff_rl_init() initializes RLTable.(max_level|max_run|index_run); max_run is unused by the MPEG-1/2 encoders (as well as SpeedHQ). Furthermore, it initializes these things twice (for two passes), but the second half of this is never used. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/mpeg12enc: Don't initialize ff_rl_mpeg2 unnecessarilyAndreas Rheinhardt2022-10-271-4/+3
| | | | | | | | | | | ff_rl_mpeg1 and ff_rl_mpeg2 differ only in RLTable.table_vlc, which ff_rl_init() does not use to initialize RLTable.max_level, RLTable.max_run and RLTable.index_run. This implies that these tables agree for ff_rl_mpeg1 and ff_rl_mpeg2; hence one can just use one of them and avoid calling ff_rl_init() ff_rl_mpeg2 alltogether.

* avcodec/mpeg12enc: Pass tables explicitly in ff_mpeg1_init_uni_ac_vlcAndreas Rheinhardt2022-10-271-7/+12

| | | | | | | It is better place for these declarations than mpeg12data.h as RL VLC are just a variant of VLCs. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/codec_internal: Add macro to set AVCodec.long_nameAndreas Rheinhardt2022-09-031-2/+2

* avcodec: Make init-threadsafety the defaultAndreas Rheinhardt2022-07-181-2/+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/mpegvideoenc: Remove ineffective optionsAndreas Rheinhardt2022-05-241-10/+1
| | | | | | | | | | | | | | | | 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 Rheinhardt2022-05-241-0/+2
| | | | | | | | (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 Rheinhardt2022-04-051-2/+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: Add FFCodec, hide internal part of AVCodecAndreas Rheinhardt2022-03-211-18/+18
| | | | | | | | | | | | | | | | 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>

* avcodec/mpegvideo: Use offset instead of pointer for vbv_delayAndreas Rheinhardt2022-01-291-1/+1
| | | | | | | | | | An offset has the advantage of not needing to be updated when the buffer is reallocated. Furthermore, the way the pointer is currently updated is undefined behaviour in case the pointer is not already set (i.e. when not encoding MPEG-1/2), because it calculates the nonsense NULL - s->pb.buf.

* avcodec/mpeg12enc: Also inline chroma subsamplingAndreas Rheinhardt2022-01-041-5/+6
| | | | | | | | | | | ff_mpeg1_encode_mb() contains two inlined calls to mpeg1_encode_mb_internal(); these calls are supposed to inline the properties depending upon the color space used. Yet inlining vertical chroma subsampling (which allows to remove complete branches and blocks depending upon them) has been forgotten.

* avcodec/mpeg12enc: Simplify check for A53 closed captionsAndreas Rheinhardt2022-01-041-1/+1
| | | | | | | | | | | | | | | The a53_cc option is only useful and meaningful for MPEG-2, yet it was accidentally added for all mpegvideo-based encoders. This means that it is possible for a53_cc to be set for other encoders as well. This commit changes this and reroutes a53_cc to the dummy field in MpegEncContext for all codecs for which it is not supported. This allows to avoid a check for the current codec in mpeg12enc.c. Also add a compile-time check for whether the MPEG-2 encoder is available while at it. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec: Constify AVCodecsAndreas Rheinhardt2021-04-271-2/+2
| | | | | | | | | | 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/mpegvideo: Deprecate bframe opts for encoders not supporting themAndreas Rheinhardt2021-04-101-0/+1
| | | | | | | | | | | 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 Rheinhardt2021-04-101-0/+7
| | | | | | | | | | | | | | 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.
