Hello list members
Any ideas and suggestions to how to get ffmpeg vulkan video transcoding
to work?
All my attempts so far are unsuccessful and finish with Conversion
failed!
Below is one code line with verbose output.

--------
My system and hardware
Kernel: 6.12.59-1-longterm arch: x86_64 bits: 64
Desktop: GNOME v: 49.1 Distro: openSUSE Tumbleweed-Slowroll 20251106
Graphics: Device-1: Intel DG2 [Arc A750] driver: i915 v: kernel
with
Vulkan v. 25.2.6, Mesa v. 25.2.6 and system ffmpeg-8 v. 8.0 (from
Packman)
I can verify the following ffmpeg Vulkan video support:
ffmpeg -hide_banner -encoders | grep vulkan
V....D av1_vulkan AV1 (Vulkan) (codec av1)
V....D ffv1_vulkan FFmpeg video codec #1 (Vulkan) (codec
ffv1)
V....D h264_vulkan H.264/AVC (Vulkan) (codec h264)
V....D hevc_vulkan H.265/HEVC (Vulkan) (codec hevc)
And by enabling both Vulkan video decode and encode support in the ANV
driver via the following environment variable
export ANV_DEBUG="video-decode,video-encode"
I can verify the following Vulkan Video Encode support:
vulkaninfo | grep -i encode
VK_KHR_video_encode_h264 : extension

VK_KHR_video_encode_h265 : extension
revision 14

I *suspect* mpeg2 decoding is not supported by Vulkan video ? Unless
someone reesurrect Mesa shaders that used to work at some point as
vulkan compute shaders ?
Try different (h264, h265, vp9, av1) input file ?
What I can tell is that ffmpeg vulkan decoding benchmarks
using mpeg2 seemingly has worked better for a long time
according to

Strange, may be some software decoding fallback patch now gets
broken in ffmpeg? URL dies not list MPEG2 as Vulkan decodeable ...
Do you have older ffmpeg (7.0, 7.1) around?
I reinstalled ffmpeg-7 v. 7.1 (Packman version) and retested the
same mpeg2video (hdv1080i50.m2t) video file using the Vulkan
decoding benchmark.
First, the normal output seemingly looks better than the previous
ffmpeg-8 test:
ffmpeg -hide_banner -init_hw_device "vulkan=vk:0" -hwaccel vulkan
-hwaccel_output_format vulkan -i hdv09_04.m2t -f null - -benchmark

Looking at speed I think ffmpeg 7.1 just demuxes, without even trying
to decode? Can you test with some light -c:v like again mpeg2 or mpeg4 ?
This is using ffmpeg-7. Please correct my code lines. I can try again
using ffmpeg-8
ffmpeg -hide_banner -init_hw_device "vulkan=vk:0" -hwaccel vulkan

I think it might fail without hwdownload,format=yuv420p filters in

May be ffmpeg 8.0 (at least as build for SuSE ) just complain at
decoding moment, instead of just silently demuxing without decoding
anything?
What happen if you set hwaccel to none or vaapi ? I guess ot should
decode in sw or via vaapi in such cases, so there will be more
realistic decoding benchmark.
ffmpeg -hide_banner -init_hw_device "vulkan=vk:0" -hwaccel -i
hdv09_04.m2t -vf "hwdownload,format=yuv420p" -c:v h264_vulkan
hdv09_04_h264_vulkan.mp4
Option hwaccel (use HW accelerated decoding) cannot be applied to output
url hdv09_04.m2t -- you are trying to apply an input option to an output
file or vice versa. Move this option before the file it belongs to.
Error parsing options for output file hdv09_04.m2t.

My previous VAAPI example (25/5-2025)

It sort of sad even h264 does not transcode via Vulkan only. You can
try to isolate was it (vulkan) decoder or vulkan encoder problem by
forcing hwaccel to none while keeping -c:v at Vulkan encoder. Look out
for hwdownload/hwupload and format filters, they still not inserted
automatically, as far as I can see.
Sorry if it sounds like too much work, as you noted this is a bit of
bleeding edge so surprises happen.

wow, never saw this one! I am afraid something in kernel driver
or ANV driver was upset ... With less Intel developers around I
am not sure if such error will be diagnosed quickly ....
You probably can try mesa3d issue tracker, may be it will get
some developer attention this way ...
I did the same transcode test using ffmpeg-7, even I'm not sure
7.1 ever supported Vulkan video encoding.
Similar errors and Conversion Failed for both the mpeg2 and mp4
video files as with ffmpeg-8.
