* avcodec/mpegvideo_enc: Deduplicate ff_mpv_generic_options-based AVClassesAndreas Rheinhardt2021-07-08
| | | | | | | | The child_class_next API relied on different AVCodecs to use different AVClasses; yet this API has been replaced by child_class_iterate. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* 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 a53cc option for encoders != MPEG-2Andreas Rheinhardt2021-04-10
| | | | | | | The MPEG-2 encoder is the only mpegvideo-based encoder that supports embedding a53 side data. 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.

* avcodec/motion_est, mpegvideo: Make pointers to static storage constAndreas Rheinhardt2020-12-31
| | | | | | | | | Modifying static storage must not happen because of multithreading (except initialization of course), so add const to the pointed-to type for pointers that point to static storage.

* avcodec/mpegvideo: Merge ff_mpv_decode_defaults into ff_mpv_decode_initAndreas Rheinhardt2020-12-31
| | | | | | | | | | | | | These two are always called directly after each other (with the exception of the calls in mpeg_decode_init() where some irrelevant modifications of the avctx (which could just as well be done before ff_mpv_decode_defaults(), because it doesn't have a pointer to the AVCodecContext at all and therefore can't see these modifications at all) are performed in between), so merge ff_mpv_decode_defaults() in ff_mpv_decode_init().

* mpegvideo_enc: add intra_penalty option for p framesRamiro Polla2019-10-24
| | | | | | | | | | | | | | | This option allows more control over the use of intra macroblocks in predictive frames. By using '-intra_penalty max', intra macroblocks are never used in predictive frames. It is useful for glitch artists to generate input material. This option allows them to split and merge two video files while maintaining fluid motion from the second video without having intra macroblocks restoring chunks of the first video.
