avcodec/vvc/refs: remove early return - Marvin Scholz git.videolan.org Git - ffmpeg.git/rss log

avformat/tee: fix multiple bsfs in tee Since 155508c6e925f4f2f5e77087a7e1925b3de735ff specifying multiple bsfs for different streams was broken: "[bsfs/a=h264_metadata:bsfs/v=h264_metadata]out.mp4|..."

avutil/hwcontext_vulkan: disable host transfers if ReBAR is disabled - Niklas Haas git.videolan.org Git - ffmpeg.git/rss log

avutil/hwcontext_vulkan: disable host transfers if ReBAR is disabled This feature fundamentally relies on host-visible VRAM, which restricts the set of available memory types to (typically) host-visible device-local ones. When resizable BAR is disabled, this memory type is usually limited to e.g. 256 MiB in size, which is just plain insufficient for allocation of general purpose GPU images, causing OOM errors on even the simplest of commands. The easiest solution is to disable host transfers entirely on machines without host-addressable VRAM. In theory, we could try and recover the use of (...)

avfilter/vf_libplacebo: correctly update SAR to reflect scaled result This aligns the behavior of vf_libplacebo with other filters in the vf_scale family, that forward any change in the SAR as a result of changing the output resolution to the output frame / link, and updates the ff_scale_adjust_dimensions() call to continue working as intended. The new behavior reflects the documentation of vf_libplacebo, which described this behavior despite that not being the way the filter worked up to this point.

However, when a filter supports both (such as vf_libplacebo itself, and possibly vf_scale in the future), linking together two such filter instances without an explicit format will default matching the input format, resulting in a redundant round trip through host RAM.

avutil: Fix linking x86 asm constants with Clang in MSVC mode - Martin Storsjö git.videolan.org Git - ffmpeg.git/rss log

avutil: Fix linking x86 asm constants with Clang in MSVC mode This fixes building with Clang in MSVC mode, for x86, which was broken in 6e49b8699657b808b7dc80033f2c3f2d0e029fa3 (in Nov 2024); previously it failed with undefined symbols for the constants defined with DECLARE_ASM_CONST, accessed via inline assembly. Before 57861911a34e1c33796be97f2b2f44e05fffd647, there was an #elif defined(__GNUC__) || defined(__clang__) case before the #elif defined(_MSC_VER) case for defining DECLARE_ASM_CONST, which included av_used.

Revert "avcodec/decode: Fix avcodec parameters when bsfs are enable by decoder" This reverts commit 1c170613975d3cbcbb5aaa469b4a3cf0df5d4c2b. The commit intended to provide certain codecs using *_mp4toannexb bitstream filters with updated (annex B) extradata (even when the user-supplied one was ISOBMFF), yet BSFs are allowed to change way more.

avcodec/pixblockdsp: Improve 8 vs 16 bit check Before this commit, the input in get_pixels and get_pixels_unaligned has been treated inconsistenly: - The generic code treated 9, 10, 12 and 14 bits as 16bit input (these bits correspond to what FFmpeg's dsputils supported), everything with <= 8 bits as 8 bit and everything else as 8 bit when used via AVDCT (which exposes these functions and purports to support up to 14 bits). - AARCH64, ARM, PPC and RISC-V, x86 ignore this AVDCT special case. - RISC-V also ignored the restriction to 9, 10, 12 and 14 for its 16bit check and treated (...)

The earlier code would nevertheless try them all for every LUT entry and use the best one; the new code meanwhile only uses one method (the fallback one (i.e. the worst)) for them all and only processes the 102 valid entries afterwards.

When there are multiple candidates for macroblock types, multiple states (namely the state before encoding the current MB, the best state among the ones already tried and the current one) need to be kept; duplicates of the PutBitContexts are among this state. The temporary buffers for them are kept on the stack in encode_thread() and their size is quite generous (MAX_MB_SIZE - 3000 bytes).

Unfortunately since that patch, fuzzing has indicated there are some structures involving pps_subpic_one_or_more_tiles_slice where tile-level checking is not sufficient. Performing the check at the CTU level should (touch wood) be the be-all and and-all of this, as CTUs are the lowest common denominator of the picture partitioning. Signed-off-by: Frank Plowman (...)

avcodec/mpeg12enc: Fix writing closed captions Broken in 6e225123d8583fdce55037b85eaef5453f201959, because ff_copy_bits() expects the amount of bits, not bytes to write.

lavf: vvc_probe: lower probe score for invalid SPS/PPS/IRAP order to avoid misdetection of mp3 as VVC The current vvc_probe function checks for SPS, PPS, and IRAP NAL units but does not enforce their detection order. This can lead to false positives when PPS or IRAP appear before SPS, causing malformed or non-compliant bitstreams to be incorrectly identified as valid VVC streams. This commit modifies the logic to use boolean flags and enforces the correct detection sequence: SPS must be detected before PPS, and PPS before IRAP. This ensures more accurate probing and prevents invalid (...)

ffv1enc_vulkan: use ff_get_encode_buffer We used to create our own buffer, but still used the DR1 flag, which is not how it's supposed to work. Instead, use ff_get_encode_buffer, and either host-map the buffer before copying each slice via GPU transfers, or just copy each slice manually if that fails or is unavailable.

cbs_apv: Check tile component sizes - Mark Thompson git.videolan.org Git - ffmpeg.git/rss log

cbs_apv: Check tile component sizes It was possible for the buffer pointers for the last tile to go over the end of the unit buffer leading to a read overflow during decode of the macroblock layer. Check all tile component sizes to prevent this case and also catch related tile size mismatch errors earlier. [DH] libavcodec/cbs_apv_syntax_template.c

avcodec/sanm: support "StarWars - Making Magic" video Videos of "StarWars - Making Magic" consist of 640x480 codec3 frames which establish a background, and a 320x240 codec48 video put on top at random left/top offsets. To support this, a new default buffer "fbuf", which holds the final image to be presented, is added, since codec37/47/48 need their 2/3 buffers to be private to themselves. The decoded result is then copied to the fbuf, honoring the left/top offsets if required. Signed-off-by: Manuel Lauss <manuel.laussⓐgmail.com> [DH] (...)

avcodec/mpeg12dec: Don't reinit upon aspect ratio change - Andreas Rheinhardt git.videolan.org Git - ffmpeg.git/rss log

avcodec/mpeg12dec: Don't reinit upon aspect ratio change The spec indeed does not allow the aspect ratio to change within a video sequence, but this does not imply that we must reinitialize the decoder if only the aspect ratio changes, as this value does not affect the decoding process at all. Moreover, our reinitialization is a bit buggy: If there is frame reordering, then the not yet output next P-frame is simply discarded upon reinit. With this patch this no longer happens when only the aspect ratio changes. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardtⓐoutlook.com> (...)
