Description (last modified by )
Hello there,
I have had the chance to test the Vulkan video encoding stack on the current ffmpeg git tip, on both Intel and NVIDIA platforms, as shown below.
So far, basic pipelines work as expected. However, more common use cases that involve handling of Vulkan-based decoding, HDR signalling and filtering (with the likes of libplacebo, etc, (as advertised to be near-feature parity with VAAPI), often fail, as shown in the examples below.
Platform info:
(a). Intel:

I've tested this implementation on Intel's ANV driver.
This was built against the mesa main branch, which now has the enablement bits for KHR_video_maintenance1 on anv.
See the related MR https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/31436
Also, the environment variables:
ANV_VIDEO_ENCODE=1 ANV_VIDEO_DECODE=1
Are also set.

Attempting to strip out HDR and a53cc with -units:v -hdr-a53_cc also results in the same failure states above.
H.264 encoding pipelines from the media samples I've tested with also fail/die the same way, with the exception of lavfi sources like this:
(a). HEVC:
ffmpeg -v verbose -init_hw_device vulkan=vk:0 \ -filter_hw_device vk \ -f lavfi -i testsrc=duration=3600:size=1920x1080:rate=60,format=nv12 -vf "hwupload" \ -b:v 2250k -minrate:v 2250k -maxrate:v 2250k -bufsize:v 2250k -c:v hevc_vulkan \ -profile:v main -r:v 60 -g:v 120 -tune:v hq -usage:v transcode -content:v rendered \ -async_depth:v 4 -refs:v 8 -b_depth:v 1 -bf:v 0 -strict -1 \ -f null /dev/null -y
That passes with NVIDIA and FAILS on Intel, and;
(b). H.264/AVC:
ffmpeg -v verbose -init_hw_device vulkan=vk:0 \ -filter_hw_device vk \ -f lavfi -i testsrc=duration=3600:size=1920x1080:rate=60,format=nv12 -vf "hwupload" \ -b:v 2250k -minrate:v 2250k -maxrate:v 2250k -bufsize:v 2250k -c:v h264_vulkan \ -profile:v high -r:v 60 -g:v 120 -tune:v hq -usage:v transcode -content:v rendered \ -async_depth:v 4 -refs:v 8 -b_depth:v 1 -bf:v 0 -strict -1 \ -f null /dev/null -y
Which passes on BOTH NVIDIA and Intel.
The flag -strict 1 has no impact on the results *except* on extremely specific edge-cases where some derivations are done via hwmap, hwupload, etc. Reproducibiluty for these edge-cases is also next to impossible across multiple runs.
On Windows:
The proprietary NVIDIA Graphics driver from the Game Ready Branch R565.90 replicates the Linux experience. Both drivers are at feature parity as far as Vulkan video encoding is concerned.
