  lavc/vvc: Skip enhancement layer NAL units - Frank Plowman git.videolan.org Git - ffmpeg.git/rss log
  lavc/vvc: Skip enhancement layer NAL units The native VVC decoder does not yet support quality/spatial/multiview scalability. Bitstreams requiring this feature could cause crashes. Patch fixes this by skipping NAL units which are not in the base layer, warning the user while doing so.

  avcodec/ac3: Remove unused fixed-point ARMv7 DSP - Geoff Hill git.videolan.org Git - ffmpeg.git/rss log
  avcodec/ac3: Remove unused fixed-point ARMv7 DSP This diff removes 4 unused ARMv7 NEON fixed-point DSP functions. The function were originally moved here by 4958f35a2 (Dec 2013). After 9e05421db (Jan 2021), as part of the refactor of the AC3 DSP to consistently use 32-bit sample format in the encoder, these functions were removed from the DSP function table, but the ARMv7 implementations were kept.

  avcodec/ac3enc: Avoid copying samples - Andreas Rheinhardt git.videolan.org Git - ffmpeg.git/rss log
  avcodec/ac3enc: Avoid copying samples Only the last 256 samples of each frame are used; the encoder currently uses a buffer for 1536 + 256 samples whose first 256 samples contain are the last 256 samples from the last frame and the next 1536 are the samples of the current frame. Yet since 238b2d4155d9779d770fccb3594076bb32742c82 all the DSP functions only need 256 contiguous samples and this can be achieved by only retaining the last 256 samples of each frame. Doing so saves 6KiB per channel. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardtⓐoutlook.com> [DH] libavcodec/ac3enc.c (...)

  vulkan_av1: add workaround for NVIDIA drivers tested on broken CTS - Lynne git.videolan.org Git - ffmpeg.git/rss log
  vulkan_av1: add workaround for NVIDIA drivers tested on broken CTS The first release of the CTS for AV1 decoding had incorrect offsets for the OrderHints values. The CTS will be fixed, and eventually, the drivers will be updated to the proper spec-conforming behaviour, but we still need to add a workaround as this will take months. Only NVIDIA use these values at all, so limit the workaround to only NVIDIA. Also, other vendors don't tend to provide accurate CTS information.

  lavc/vvc: Increase size of ctb_size_y - Frank Plowman git.videolan.org Git - ffmpeg.git/rss log
  lavc/vvc: Increase size of ctb_size_y sps_log2_ctu_size_minus5 is between 0 and 2, with 3 reserved for future use. The VVC decoder allows sps_log2_ctu_size_minus5 to be 3, and so ctb_size_y should be at least 16 bits to prevent overflows. An alternative patch would leave sps_log2_ctu_size_minus5 as 8 bits and disallow sps_log2_ctu_size_minus5 = 3. Signed-off-by: Frank Plowman <postⓐfrankplowman.com> [DH] libavcodec/vvc/ps.h
