Wanted to build the newest ffmpeg from git today (sept 4 2023), but to
my surprise configuring failed with the error message
ERROR: vulkan requested but not found
However vulkan is installed and active on my system, searching in the
config.log revealed that indeed vulkan was found, but the version was
to old. The expected version was 1.3.255 but the installed version is:
1.3.239 (from latest stable MESA 23.1.6)
This is however a problem, as this version has indeed been released
(jun 2023) by the Khronos group, but is not yet implemented anywhere
except in the most bleeding edge vulkan sources. Even the oibaf ppa
does not have it yet (it is on 1.3.250)
My last build from git (Aug 25 2023) went flawless so somewhere in
between the needed vulkan version was updated. As there is no
(relatively easy way) to get the needed vulkan drivers for my system,
are there really changes made in ffmpeg to make this new (as yet
unobtainable) vulkan version necessary? Or will building with the
older version break things?
Just tested building with older vulkan version (bypassing version
check). This does indeed break the build, so had to resort to disabling
vulkan in the build to get a new working version of ffmpeg. Do not use
vulkan often in ffmpeg so I can cope with it for now.
