I have recently tested the following patches:

0001-Add-Vulkan-detection-to-buildsystem.patch
0004-External-libzimg-support-for-buildsystem.patch
0002-Add-libplacebo-Vulkan-filter-detection.patch
0019-Set-postprocessing-in-libtheora-decoder.patch
0002-Make-x265_hidepth-actually-work.patch
0023-Fixup-seg-name-to-segment-so-format-gui-button-work.patch
0003-Fix-libplacebo-enabling-was-typoed-wrong.patch

Other patches are already in git, I'm not sure which ones still need to be tested. I need number 0004 (libzimg), otherwise I can't compile. The others work fine. I don't quite understand what I should test with x265.

Another thing, I wanted to create encoding presets with AMD's AMF framework (the equivalent of Nvidia's NVENC), since it's open source and has been separated from amdgpu-pro, but I can't enable it in the ./configure phase. Any idea how to do this?

One last thing, not important, just something I'm curious about:
When I load an av1 media file, I get this warning:

"Decoder libdav1d does not support device type vulkan.
HW device init failed, using SW decode"

I wanted to try disabling dav1d and going back to the classic libaom_av1 to test whether hardware-accelerated Vulkan had reached or exceeded the performance of dav1d (which is very fast but software-based). I can't disable dav1d; I tried editing the “decode.opts” file by commenting out the line:

remap_video_decoder libaom-av1=libdav1d

Or by replacing libdav1d with av1_vulkan; but I always get the same warning indicating that dav1d is still running. I also tried disabling dav1d in the ./configure phase (--disable-libdav1d) but it is not taken into account and I continue to get the same warning. Do you know how I could do this? (I remind you that this is just my curiosity, it is not important).
