* avcodec: Constify AVCodecsAndreas Rheinhardt2021-04-271-1/+1
| | | | | | | | | | 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 Rheinhardt2021-04-271-1/+1
| | | | | | | | | | | 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 Rheinhardt2021-04-101-0/+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 a53cc option for encoders != MPEG-2Andreas Rheinhardt2021-04-101-0/+3
| | | | | | | 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 Rheinhardt2021-04-101-0/+2
| | | | | | | | | | | | | | 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.
