* avcodec/mpeg12dec: Remove redundant mpeg_enc_ctx_allocatedAndreas Rheinhardt2024-04-08
| | | | | | | | Use context_initialized from the underlying MpegEncContext instead. Also don't check before ff_mpv_common_end() in mpeg_decode_end(). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/mpegvideo_dec: Remove redundant code to reset keyframe flagAndreas Rheinhardt2024-04-08
| | | | | | These AVFrames are blank and therefore the flag is already unset. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/mpegvideo_dec: Remove obsolete current_picture_ptr reuse codeAndreas Rheinhardt2024-04-08
| | | | | | Obsolete since at least 74d623914f02aa79447df43a742efd0929dded04. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/mpeg12dec: Remove unnecessary FFCodec.closeAndreas Rheinhardt2024-04-08
| | | | | | | The ipu decoder never calls ff_mpv_common_init() or allocates anything else that would need to be freed. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/mpegvideo_dec: Don't emit non-keyframe warning for H.261Andreas Rheinhardt2024-04-08
| | | | | | | | | H.261 does not have keyframes (or indeed frame types) at all, so this warning is not warranted. Also remove an always-true check while at it. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/mpeg12dec: Don't pretend MPEG-1/2 to support alphaAndreas Rheinhardt2024-04-08
| | | | | | | | (FF_PTR_ADD has to be kept although MPEG-1/2 only supports YUV pixel formats because our decoder also supports decoding to AV_PIX_FMT_GRAY8 depending upon CONFIG_GRAY.) Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/mpeg12dec: Remove redundant checkAndreas Rheinhardt2024-04-08
| | | | | | This code only gets executed for the first field. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/mpegvideo_dec, mpeg12dec: Move MPEG1/2 code to mpeg12dec.cAndreas Rheinhardt2024-04-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Up until now, ff_mpv_frame_start() offsets the data of the current picture and doubles the linesizes of all pictures if the current picture is field-based so that data and linesize allow to address the current field only. This is done based upon the current picture_structure value. Only two mpegvideo-based decoders ever set this field: mpeg1/2 and VC-1; but the latter only does it after ff_mpv_frame_start() (when using hardware-acceleration and in order to signal it to the DXVA2 hwaccel) in which case no offset is applied in ff_mpv_frame_start(). So only one decoder actually wants this offset*; therefore move the code performing it to mpeg12dec.c. *: VC-1 doubles linesize when using field_mode (not only the picture's linesize, but also uvlinesize and linesize), yet it does not offset anything. This is further proof that this should not be performed generically. Also move MPEG-1/2 specific setting of the top-field-first flag. (The change here implies that the AVFrame in current_picture may have different top-field-first flags than the AVFrame from current_picture_ptr, but this doesn't matter as only the latter's are used.)

* avcodec/mpegvideo_enc: Don't update current_picture unnecessarilyAndreas Rheinhardt2024-04-08
| | | | | | | | current_picture is not changed after frame_start() at all and it therefore does not need to be updated (i.e. copied to the slice thread contexts) a second time. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* lavc/vvc: Error if SPS ID is duplicated within CVSFrank Plowman2024-04-07
| | | | | | | | | | | | | | | | | | | | Key line from the spec is: "All SPS NAL units with a particular value of sps_seq_parameter_set_id in a CVS shall have the same content." Prior to this patch, the VVC decoder's behaviour on encountering a duplicated SPS ID (within the entire bitstream, not restricted to a CVS) was simply to replace the entry in the SPS lookup table with the new data. Illegal bitstreams with multiple SPSs in the same CVS sharing an ID but differing elsewhere could cause all manner of issues. The patch tracks which SPS IDs have been used in the given CVS using the new sps_id_used field of VVCParamSets. If it encounters an SPS with an ID already in use and whose content differs from the previous SPS, it throws an AVERROR_INVALIDDATA. Signed-off-by: Frank Plowman <post@frankplowman.com>

* avocdec/ass: simplify linebreaksOneric2024-04-06
| | | | | | ff_ass_subtitle_header_* still used explicit CRLF linebreaks eventhough they will get normalised to LF later since commit 7bf1b9b35769b37684dd2f18a54f01d852a540c8. Just directly use LF.
* avcodec/ass,webvttdec: implement more portable curly brace escapesOneric2024-04-06
| | | | | | | | | | | | | Unlike what the old comment suggested, standard ASS has no character escape mechanism, but a closing curly bracket doesn't even need one. For manual authored sub files using a full-width variant of an appropriate font and with scaling and spacing modifiers is a common workaround. This is not an option here, but we can still make things much less bad. Now the desired opening bracket still shows up in libass, and standard renders will merely display a backslash in its place instead of stripping the following text like before.
* avcodec/ass,webvttdec: fix handling of backslashesOneric2024-04-06
| | | | | | | Backslashes cannot be escaped by a backslash in any ASS renderer, but unless followed by specific characters it is just printed out. Insert a word-joiner character after a backslash to break up active sequences without changing the visual output.

* fate/ffmpeg: Avoid dependency on samplesAndreas Rheinhardt2024-04-05
| | | | | | | | | | | | | | | Creating vsynth_lena.yuv needs the FATE suite, yet several tests in ffmpeg.mak without a dependency on samples used it as input file. Fix this by using vsynth1.yuv (which does not have such a dependency) instead. Also use vsynth1.yuv in fate-shortest to avoid the samples dependency in this test, too. Fixes ticket #10947.
