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:

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:

And on OpenCL, I get:

'''In conclusion:'''
1. 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)
}}}
2. 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.
