I did a compilation with ffmpeg 6.1 and everything went well. Thanks Phyllis.

(Note x Phyllis: the new "zoneplate" filter gives no error but if you
try to use it the error comes up:
err: Function not implemented)

I tried making a new build by enabling vulkan as described in the
following links:

https://trac.ffmpeg.org/wiki/HWAccelIntro#Vulkan
https://ffmpeg.org/ffmpeg-filters.html#Vulkan-Video-Filters

It compiles without errors using "--enable-vulkan" and
"--enable-libglslang" while crashing using "--enable-libshaderc". For
the latter crash see cin5_shader.tar.gz

In the case of "--enable-libglslang" I have no build errors, however,
in the end, the ".../bin/cin" program is not created and therefore
CinGG does not start. See the log cin5_glslang.tar.gz

I don't see any errors in the log; there are many lines like:

"/home/paz/cinelerra5/cinelerra-5.1/thirdparty/ffmpeg-6.1/libavfilter/vulkan_glslang.c:182:(.text+0xcf):
undefined reference to `glslang_shader_create'"

undefined reference is usually fatal link error, no wonder you have no binary ..

probably you need to add some additional libs to ldflags as well ....

But they are not error lines or warning lines. I think it's looking
for vulkan device initialization but can't find it and leave it
alone....
