On 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 revision 14
VK_KHR_video_encode_h265 : extension revision 14
VK_KHR_video_encode_queue : extension revision 12
queueFlags = QUEUE_VIDEO_DECODE_BIT_KHR | QUEUE_VIDEO_ENCODE_BIT_KHR
VIDEO_CODEC_OPERATION_ENCODE_H264_BIT_KHR
VIDEO_CODEC_OPERATION_ENCODE_H265_BIT_KHR
while AV1 seemingly has only Video Decode support so far:
vulkaninfo | grep -i av1
VK_KHR_video_decode_av1 : extension revision 1
VIDEO_CODEC_OPERATION_DECODE_AV1_BIT_KHR
placeholder = AV1 Decode (4:2:0 8-bit) Main with film grain support
placeholder = AV1 Decode (4:2:0 8-bit) Main without film grain support
placeholder = AV1 Decode (4:2:0 10-bit) Main with film grain support
placeholder = AV1 Decode (4:2:0 10-bit) Main without film grain support
But does it actually work? ;)
I think prores (not prores RAW) work exist in ffmpeg.git for now ....
