* 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/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/mpegvideo_enc: Make mpv_encode_defaults thread-safeAndreas Rheinhardt2021-01-25
| | | | | | | | | This is a prerequisite for making any encoder that uses ff_mpv_encode_init() init-threadsafe; it already makes the AMV, the MJPEG and the MPEG-1/2 encoders init-threadsafe.

* avcodec/mpeg12: Don't initialize encoder-only parts of RLTableAndreas Rheinhardt2020-12-31
| | | | | | | | | | | ff_mpeg12_init_vlcs() currently initializes index_run, max_level and max_run of ff_rl_mpeg1/2; yet the only user of these fields is the MPEG-1/2 encoder which already initializes these tables on its own. So remove the initializations in ff_mpeg12_init_vlcs(); this also simplifies making ff_mpeg12_init_vlcs() thread-safe.

* avcodec/speedhqenc: Call correct functionAndreas Rheinhardt2020-12-11
| | | | | | | | | | | | | | | | | | | Up until now, the SpeedHQ encoder called a wrong function for init: void ff_init_uni_ac_vlc(const uint8_t huff_size_ac[256], uint8_t *uni_ac_vlc_len); Yet the first argument actually used is of type RLTable; the size of said struct is less than 256 if the size of a pointer is four, leading to an access beyond the end of the RLTable. This commit fixes this by calling the actually intended function: init_uni_ac_vlc() from mpeg12enc.c. It was intended to use this function [1], yet doing so was forgotten when the patch was actually applied.

* avcodec/mpeg12enc: Disallow using MPEG-2 intra VLC table for mpeg1videoAndreas Rheinhardt2020-12-02
| | | | | | | | | | | | Using MPEG-2 intra VLC tables is spec-incompliant for MPEG-1 and given that an MPEG-1 bitstream can't signal whether MPEG-2 intra VLC tables have been used the output is broken. Therefore this option is removed immediately without any deprecation period.

* avcodec/mpeg12enc: Always initialize MPEG-2 intra VLC table lengthsAndreas Rheinhardt2020-11-25
| | | | | | | | | | | | | The MPEG-1/2 encoders initialize several tables once during the first time one of the encoders is initialized; the table for MPEG-2 intra VLC lengths is only initialized if it is used for this encoder instance. This implies that if the first MPEG-1/2 encoder to be initialized does not use it, it will never be initialized even if a later encoder instance makes use of them. Fix this by initializing this table unconditionally. Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

| | | | | | | | | This function is so extremely simple that it is preferable to make it inline rather than deal with all the complications arising from it being an exported symbol. Keep avpriv_align_put_bits() around until the next major bump to preserve ABI compatibility.
