[FFmpeg-devel] [PATCH 0/3] avutil/dict2: Add AVDictionary2 with hash-based lookup

This is probably a PREMIERE. This whole patchset has been antirely authored by AI, wich means that I haven't written a single line of code. Still it had required a lot of strong guidance, so it wouldn't have been able to do it alone. Even though it was an experiment, it is still meant to be a seri

[FFmpeg-devel] [PATCH 17/18] vulkan: add support for expect/assume

This commit adds support for compiler hints. While on AMD these are not used/needed, Nvidia benefits from them, and gives a sizeable 10% speedup on 4k. --- libavcodec/vulkan/ffv1_dec.comp | 16 libavcodec/vulkan/rangecoder.comp | 12 ++-- libavutil/hwcontext_vulkan.c

[FFmpeg-devel] [PATCH 13/18] ffv1/vulkan: redo context count tracking and quant_table_idx management

This commit also makes it possible for the encoder to choose a different quantization table on a per-slice basis, as well as adding this capability to the decoder. Also, this commit fully fixes decoding of context=1 encoded files. --- libavcodec/ffv1_vulkan.h | 2 +- libavcodec/ffv1

[FFmpeg-devel] [PATCH 01/18] hwcontext_vulkan: disable descriptor buffer extension on Intel

Temporary workaround. Will be replaced with a version check once a fix is in the works and a known next version for Mesa with a fix is known. --- libavutil/hwcontext_vulkan.c | 5 + 1 file changed, 5 insertions(+) diff --git a/libavutil/hwcontext_vulkan.c b/libavutil/hwcontext_vulkan.c index

[FFmpeg-devel] [PATCH 18/18] vulkan_ffv1: add cached symbol reader for AMD

Speeds up everything on AMD by 3x. This uses 32 local invocations to load state into cache, as well as to do the RCT faster. --- libavcodec/vulkan/ffv1_dec.comp | 71 - libavcodec/vulkan_ffv1.c| 7 +++- 2 files changed, 50 insertions(+), 28 deletions(-) di

[FFmpeg-devel] [PATCH 15/18] vulkan_ffv1: remove need for scratch data during setup

[FFmpeg-devel] [PATCH 12/18] vulkan_ffv1: cache only 2 lines when decoding RGB

This reduces the intermediate VRAM used for RGB decoding by a factor of 100x for 6k video. This also speeds the decoder up by 16% for 4k RGB24 and 31% for 6k video. This is equivalent to what the software decoder does, but with less pointers. --- libavcodec/vulkan/Makefile | 3 +- liba
