ffmpeg won't build using the --ffmpeg-git-checkout-version flag

[echoxxzz]

If I try and build ffmpeg using the --ffmpeg-git-checkout-version flag the ffmpeg build fails with the following error:

ERROR: nvenc requested but not found.

eek. what does the configure log say about it ?

[echoxxzz]

Here are my logs. I included the logs using both ffmpeg n6.1-dev and n6.0.

config.logs.zip

Unfortunately the log does not seem very helpful. Is there another more detailed log, say in the ffbuild folder or something ?

Full command line please?

The full command I was using was:

cross_compile_ffmpeg.sh --disable-nonfree=n --compiler-flavors=win64 --prefer-stable=y --ffmpeg-git-checkout-version=n6.0

After a bit of trial and error I was able to narrow it down to commit: 03823ac0c6a38bd6ba972539e3203a592579792f.

If I use that commit or after it works fine but if I use any commit before it the build script fails with the nvenc requested but not found error.

This kind of makes sense since this was a change to the configure script related to nvenc.

it's working now?

No it still only works using any ffmpeg commit after 03823ac0c6a38bd6ba972539e3203a592579792f. I think it has something to do with the new nvenc headers SDK 12.1 and it probably can't be fixed since the versions of the nvenc headers seem to have to match the ffmpeg configure script.

gotcha, yeah you'd probably want to just disable nvenc for older builds then (manually), sorry for the confusion
