* avcodec/mpegvideo: Move loop_filter to {H263Dec,MPVEnc,VC1}ContextAndreas Rheinhardt2025-07-031-0/+1
| | | | Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/vc1: Don't use MpegEncContext.blockAndreas Rheinhardt2025-07-031-0/+4
| | | | | | | | Instead add the necessary blocks directly to VC1Context (only six are needed, not 12 as ff_mpv_common_init() currently allocates). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/vc1: Stop using MpegEncContext.gbAndreas Rheinhardt2025-07-031-0/+2
| | | | | | | Add a GetBitContext to VC1Context instead. This is in preparation for removing MpegEncContext.gb. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/vc1: Only keep mb_type[0]Andreas Rheinhardt2025-06-211-1/+1
| | | | | | The chroma mb_type[1] and mb_type[2] pointers are unused. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/vc1: Remove write-only qs_lastAndreas Rheinhardt2025-05-161-1/+0

* avcodec/mpegvideo: Move MSMPEG4 fields to MSMPEG4 contextsAndreas Rheinhardt2025-03-261-0/+4
| | | | | | | Several fields are not used by any generic code and can therefore be moved to more specialized contexts. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/vc1: Add max_b_frames field to VC1ContextAndreas Rheinhardt2025-03-041-0/+1
| | | | | | | | Don't reuse MpegEncContext.max_b_frames, which is supposed to be encoder-only. Reviewed-by: Ramiro Polla <ramiro.polla@gmail.com> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/vc1_mc: Don't check AVFrame INTERLACE flagsAndreas Rheinhardt2024-06-121-0/+1
| | | | | | | Instead cache these values in VC1Context to avoid the indirection and AND. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/vc1: Avoid superfluous VLC structuresAndreas Rheinhardt2023-10-311-5/+5
| | | | | | | | | | | For all VLCs here, the number of bits of the VLC is write-only, because it is hardcoded at the call site. Therefore one can replace these VLC structures with the only thing that is actually used: The pointer to the VLCElem table. And in some cases one can even avoid this. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/vc1dec: Factor (re)initializing code outAndreas Rheinhardt2022-11-061-1/+1
| | | | | | | This is in preparation for removing the msmpeg4 dependency from VC-1. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/vc1: re-implement and expand VC-1 loop filteringJerome Borsboom2018-04-251-0/+4
| | | | | | | | | The existing implementation did loop filtering for progressive frames only. This rewritten version implements loop filtering for all applicable frame types for both progessive and frame/field-interlace. Signed-off-by: Jerome Borsboom <jerome.borsboom@carpalis.nl>

* avcodec/vc1: add bitstream elements for VAAPI VC-1 interlaced decodingJerome Borsboom2018-03-041-0/+6
| | | | | | | We need to pass more bitstream elements to the VAAPI VC-1 decoder in order to start doing interlaced decoding in hardware. Signed-off-by: Jerome Borsboom <jerome.borsboom@carpalis.nl>

| * vc1dec: Redesign the intensity compensationMichael Niedermayer2013-05-281-3/+5
| | | | | | | | | | | | | | | | | | | | | | Use the intensity-compensated reference frame for subsequent fields/B-frames. Since we currently don't change the reference frame we have to maintain lookup tables for intensity compensation in the following dependent frames. Signed-off-by: Martin Storsjö <martin@martin.st>
| * vc1dec: Shuffle field MVs after decoding, not beforeMichael Niedermayer2013-05-281-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | This simplifies the code since copying MVs to the reference is not needed anymore (and maybe something about fixing artifacts). Also remove the unused mv_f_last. Fixes a small number of artifacts in black_screen_VC-1.mkv and several more artifacts in other videos. Signed-off-by: Martin Storsjö <martin@martin.st>

| | | | | | | | | | | | | | | | The existing implementation had little to do with VC1. This could be implemented by adjusting the reference frames ithemselfs but that would make frame multi-threading difficult. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

| | | | | | | | | | | | The init functions marked as av_cold have to be executed in any case, so there is no gain from trying to mark paths leading to such functions as unlikely.
