Description
Hello there,
I'm trying to get the Vulkan H/W filters, specifically scale_vulkan working with NVIDIA GPUs, but to no avail.
With the hwupload filter, using the derive_device option as documented:
ffmpeg -threads 1 -loglevel info -nostdin -y \ -fflags +genpts-fastseek \ -init_hw_device cuda=cuda:0 -filter_hw_device cuda -hwaccel_device cuda -hwaccel nvdec \ -reinit_filter 1 -vsync 1 -async 1 -filter_threads 2 -filter_complex_threads 2 \ -i feeds.mp4 -filter_complex \ "[0:v]hwupload=derive_device=vulkan,split=2[s0][s1]; \ [s0]scale_vulkan=w=1920:h=1080:scaler=0[v0]; \ [s1]scale_vulkan=w=1280:h=720:scaler=0[v1]" \ -map "[v0]" -b:v:0 5800k -minrate:v:0 5800k -maxrate:v:0 5800k -bufsize:v:0 5800k -c:v:0 h264_nvenc -r:v:0 ntsc \ -profile:v:0 high -preset:v:0 llhp -rc:v:0 cbr_ld_hq -g:v:0 60 -gpu:v:0 0 -strict_gop:v:0 1 -bf:v:0 0 \ -map "[v1]" -b:v:1 4000k -minrate:v:1 4000k -maxrate:v:1 4000k -bufsize:v:1 4000k -c:v:1 h264_nvenc -r:v:1 ntsc \ -profile:v:1 high -preset:v:1 llhp -rc:v:1 cbr_ld_hq -g:v:1 60 -gpu:v:1 0 -strict_gop:v:1 1 -bf:v:1 0 \ -map 0:a -c:a libfdk_aac -ac 2 -ar 48000 -b:a 128k \ -flags +global_header+cgop \ -max_muxing_queue_size 9000000 -threads 2 -f tee \ "[select=\'v:0,a\'f=mp4]'hq.mp4'| \ [select=\'v:1,a\'f=mp4]'med.mp4'"

At this stage, it may have to do with the supported pixel format(s), as the scale_vulcan filter (at the present) does not support texture conversion, as noted in the commit https://git.ffmpeg.org/gitweb/ffmpeg.git/commit/d95c509cc64372f8b37d89310250785224751a90.
However, attempting to request for specific pixel formats from the decoder, such as nv12, paired with the hwmap filter results in failure too:

I'm assuming that the warnings on the two Vulkan extensions not being found, ie "VK_EXT_external_memory_dma_buf" and "VK_EXT_image_drm_format_modifier" may point to issues with the NVIDIA driver.

In conclusion:
- What pixel formats are supported by the scale_vulkan filter? So far, no such information is provided in the documentation. See the output of:
ffmpeg -h filter=scale_vulkan
Filter scale_vulkan
Scale Vulkan frames
Inputs:
#0: default (video)
Outputs:
#0: default (video)
scale_vulkan AVOptions:
w <string> ..FV...... Output video width (default "iw")
h <string> ..FV...... Output video height (default "ih")
scaler <int> ..FV...... Scaler function (from 0 to 2) (default bilinear)
bilinear 0 ..FV...... Bilinear interpolation (fastest)
nearest 1 ..FV...... Nearest (useful for pixel art)
- With the new code path for HW-HW transfers, as documented in this patch work: https://git.ffmpeg.org/gitweb/ffmpeg.git/commit/d7210ce7f5418508d6f8eec6e90d978e06a2d49e
What CLI options, apart from passing the hardware name to initialize via ffmpeg as shown above, are required to get the scale_vulkan filter working on NVIDIA hardware? As shown above, neither hwupload nor hwmap with device derivation for Vulkan yields usable results.

Hello @richardpl ,
Your advice above works very well.
Here are two samples that work, one with NVDEC and the other without:
(a). With nvdec:
ffmpeg -threads 1 -loglevel info -nostdin -y \ -fflags +genpts-fastseek \ -init_hw_device vulkan=gpu:0.0 -filter_hw_device gpu \ -hwaccel nvdec -hwaccel_device 0 -extra_hw_frames 2 \ -reinit_filter 1 -vsync 1 -async 1 -filter_threads 2 -filter_complex_threads 2 \ -i feeds.mp4 -filter_complex \ "[0:v]format=nv12,hwupload,split=2[s0][s1]; \ [s0]scale_vulkan=w=1920:h=1080:scaler=0,hwdownload,format=nv12[v0]; \ [s1]scale_vulkan=w=1280:h=720:scaler=0,hwdownload,format=nv12[v1]" \ -map "[v0]" -b:v:0 5800k -minrate:v:0 5800k -maxrate:v:0 5800k -bufsize:v:0 5800k -c:v:0 h264_nvenc -r:v:0 ntsc \ -profile:v:0 high -preset:v:0 llhp -rc:v:0 cbr_ld_hq -g:v:0 60 -gpu:v:0 0 -strict_gop:v:0 1 -bf:v:0 0 \ -map "[v1]" -b:v:1 4000k -minrate:v:1 4000k -maxrate:v:1 4000k -bufsize:v:1 4000k -c:v:1 h264_nvenc -r:v:1 ntsc \ -profile:v:1 high -preset:v:1 llhp -rc:v:1 cbr_ld_hq -g:v:1 60 -gpu:v:1 0 -strict_gop:v:1 1 -bf:v:1 0 \ -map 0:a -c:a libfdk_aac -ac 2 -ar 48000 -b:a 128k \ -flags +global_header+cgop \ -max_muxing_queue_size 9000000 -threads 2 -f tee \ "[select=\'v:0,a\':f=mp4]'hq.mp4'| \ [select=\'v:1,a\':f=mp4]'med.mp4'"
(b). No hwaccel decode:
ffmpeg -threads 1 -loglevel info -nostdin -y \ -fflags +genpts-fastseek \ -init_hw_device vulkan=gpu:0.0 -filter_hw_device gpu \ -reinit_filter 1 -vsync 1 -async 1 -filter_threads 2 -filter_complex_threads 2 \ -i feeds.mp4 -filter_complex \ "[0:v]format=nv12,hwupload,split=2[s0][s1]; \ [s0]scale_vulkan=w=1920:h=1080:scaler=0,hwdownload,format=nv12[v0]; \ [s1]scale_vulkan=w=1280:h=720:scaler=0,hwdownload,format=nv12[v1]" \ -map "[v0]" -b:v:0 5800k -minrate:v:0 5800k -maxrate:v:0 5800k -bufsize:v:0 5800k -c:v:0 h264_nvenc -r:v:0 ntsc \ -profile:v:0 high -preset:v:0 llhp -rc:v:0 cbr_ld_hq -g:v:0 60 -gpu:v:0 0 -strict_gop:v:0 1 -bf:v:0 0 \ -map "[v1]" -b:v:1 4000k -minrate:v:1 4000k -maxrate:v:1 4000k -bufsize:v:1 4000k -c:v:1 h264_nvenc -r:v:1 ntsc \ -profile:v:1 high -preset:v:1 llhp -rc:v:1 cbr_ld_hq -g:v:1 60 -gpu:v:1 0 -strict_gop:v:1 1 -bf:v:1 0 \ -map 0:a -c:a libfdk_aac -ac 2 -ar 48000 -b:a 128k \ -flags +global_header+cgop \ -max_muxing_queue_size 9000000 -threads 2 -f tee \ "[select=\'v:0,a\':f=mp4]'hq.mp4'| \ [select=\'v:1,a\':f=mp4]'med.mp4'"
See the repeated use of the hwdownload filters trailing each scale_vulcan instance.
Where it all falls apart is if you attempt device derivation via hwupload.
The example above with NVDEC will fail if you attempt device derivation in hwupload so as to re-use the same context for hwaccel via nvdec:
ffmpeg -threads 1 -loglevel info -nostdin -y \ -fflags +genpts-fastseek \ -init_hw_device vulkan=gpu:0.0 -filter_hw_device gpu \ -hwaccel nvdec -hwaccel_device cuda -extra_hw_frames 2 \ -reinit_filter 1 -vsync 1 -async 1 -filter_threads 2 -filter_complex_threads 2 \ -i feeds.mp4 -filter_complex \ "[0:v]format=nv12,hwupload=derive_device=cuda,split=2[s0][s1]; \ [s0]scale_vulkan=w=1920:h=1080:scaler=0,hwdownload,format=nv12[v0]; \ [s1]scale_vulkan=w=1280:h=720:scaler=0,hwdownload,format=nv12[v1]" \ -map "[v0]" -b:v:0 5800k -minrate:v:0 5800k -maxrate:v:0 5800k -bufsize:v:0 5800k -c:v:0 h264_nvenc -r:v:0 ntsc \ -profile:v:0 high -preset:v:0 llhp -rc:v:0 cbr_ld_hq -g:v:0 60 -gpu:v:0 0 -strict_gop:v:0 1 -bf:v:0 0 \ -map "[v1]" -b:v:1 4000k -minrate:v:1 4000k -maxrate:v:1 4000k -bufsize:v:1 4000k -c:v:1 h264_nvenc -r:v:1 ntsc \ -profile:v:1 high -preset:v:1 llhp -rc:v:1 cbr_ld_hq -g:v:1 60 -gpu:v:1 0 -strict_gop:v:1 1 -bf:v:1 0 \ -map 0:a -c:a libfdk_aac -ac 2 -ar 48000 -b:a 128k \ -flags +global_header+cgop \ -max_muxing_queue_size 9000000 -threads 2 -f tee \ "[select=\'v:0,a\':f=mp4]'hq.mp4'| \ [select=\'v:1,a\':f=mp4]'med.mp4'"
Error message:

You need to tell the decoder to actually output to GPU memory - by default hwaccel always copies back to system memory.
So here's an example that decodes with nvdec, scales with vulkan and encodes with nvenc, all in GPU memory with no copy back to system memory. If you want to encode with a software encoder, then you need the hwdownload,format=nv12 at the end instead of the second hwupload.
ffmpeg -hwaccel nvdec -hwaccel_output_format cuda -i in.mp4 -init_hw_device cuda=cuda:0 -filter_hw_device cuda -vf hwupload=derive_device=vulkan,scale_vulkan=w=1920:h=1440,hwupload=derive_device=cuda -c:v hevc_nvenc out.mp4

ffmpeg -threads 1 -loglevel info -nostdin -y \ -fflags +genpts-fastseek \ -init_hw_device cuda=cuda:0 -filter_hw_device cuda \ -hwaccel nvdec -hwaccel_output_format cuda -extra_hw_frames 2 \ -reinit_filter 1 -vsync 1 -async 1 -filter_threads 2 -filter_complex_threads 2 \ -i feeds.mp4 -filter_complex \ "[0:v]hwupload=derive_device=vulkan,split=2[s0][s1]; \ [s0]scale_vulkan=w=1920:h=1080:scaler=0,hwupload=derive_device=cuda[v0]; \ [s1]scale_vulkan=w=1280:h=720:scaler=0,hwupload=derive_device=cuda[v1]" \ -map "[v0]" -b:v:0 5800k -minrate:v:0 5800k -maxrate:v:0 5800k -bufsize:v:0 5800k -c:v:0 h264_nvenc -r:v:0 ntsc \ -profile:v:0 high -preset:v:0 llhp -rc:v:0 cbr_ld_hq -g:v:0 60 -gpu:v:0 0 -strict_gop:v:0 1 -bf:v:0 0 \ -map "[v1]" -b:v:1 4000k -minrate:v:1 4000k -maxrate:v:1 4000k -bufsize:v:1 4000k -c:v:1 h264_nvenc -r:v:1 ntsc \ -profile:v:1 high -preset:v:1 llhp -rc:v:1 cbr_ld_hq -g:v:1 60 -gpu:v:1 0 -strict_gop:v:1 1 -bf:v:1 0 \ -map 0:a -c:a libfdk_aac -ac 2 -ar 48000 -b:a 128k \ -flags +global_header+cgop \ -max_muxing_queue_size 9000000 -threads 2 -f tee \ "[select=\'v:0,a\':f=mp4]'hq.mp4'| \ [select=\'v:1,a\':f=mp4]'med.mp4'"
That command works and its' exceptionally *faster* than the prior variant above.
The encoder in this case runs at about ~10x on an RTX 2080.
The previous command (with the repeated hwdownload instances) run at a paltry ~1.5x.
That's a ~7x speed up!
Thank you so much :-)
I can now (safely) close this ticket.

Great. Mind you, I would assume scale_cuda would be a better choice in your scenario, if that's the only filter you're actually using, and would probably be even faster.
