  lavc/vvc: Validate temporal MVP references - Frank Plowman git.videolan.org Git - ffmpeg.git/rss log
  lavc/vvc: Validate temporal MVP references Per VVCv3 p. 157, the collocated reference picture used in temporal motion vector prediction must have RprConstraintsActiveFlag equal to zero and the same CTU size as the current picture. Add these checks, fixing crashes decoding some fuzzed bitstreams. Additionally, only set up the collocated reference picture if it is actually going to be used (i.e. if ph_temporal_mvp_enabled_flag is 1), else legal RPR bitstreams will fail the new checks.

  lavc/sbrdsp: fix potential overflow in noise table - Rémi Denis-Courmont git.videolan.org Git - ffmpeg.git/rss log
  lavc/sbrdsp: fix potential overflow in noise table Since the SBR noise application optimisations are currently restricted to hardware with 128-bit vectors, and use a quadruple multipler, they can load up to 16 32-bit elements. But the "loads" are of 2 segments, or 16 pairs of single precision float. Thus we need to expand the dupiclated section of the noise table from 2x8 to 2x16 to avoid overflows.

  lavc/flacdsp: do not assume maximum R-V VL - Rémi Denis-Courmont git.videolan.org Git - ffmpeg.git/rss log
  lavc/flacdsp: do not assume maximum R-V VL This loop correctly assumes that VLMAX=16 (4x128-bit vectors with 32-bit elements) and 32 >= pred_order > 16. We need to alternate between VL=16 and VL=t2=pred_order-16 elements to add up to pred_order. The current code requests AVL=a2=pred_order elements. In QEMU and on thte K230 hardware, this sets VL=16 as we need. But the specification merely guarantees that we get: ceil(AVL / 2) <= VL <= VLMAX. For instance, if pred_order equals 27, we could end up with VL=14 or VL=15 instead of VL=16. So instead, request literally VLMAX=16. [DH] (...)

  lavc/vp9: reset segmentation fields when segmentation isn't enabled Fields under the segmentation switch are never reset on a new frame, and retain the value from the previous frame. This bugs out a bunch of hwaccel drivers when segmentation is disabled but update_map isn't reset because they don't ignore values behind switches. This commit also resets the temporal field, though it may not be required. We also do this for vp8 [1] so this commit is just mirroring the vp8 logic.

  libavcodec/x86/vvc: Add AVX2 DMVR SAD functions for VVC Implements AVX2 DMVR (decoder-side motion vector refinement) SAD functions. DMVR SAD is only calculated if w >= 8, h >= 8, and w * h > 128. To reduce complexity, SAD is only calculated on even rows. This is calculated for all video bitdepths, but the values passed to the function are always 16bit (even if the original video bitdepth is 8). The AVX2 implementation uses min/max/sub. Additionally this changes parameters dx and dy from int to intptr_t. This allows dx & dy to be used as pointer offsets without needing to use (...)

This meant that files that were previously seekable, albeit with some skipped frames, were not seekable at all now. Relax this heuristic a bit by giving up on seeking to a valid point (...)
