Question / Help [Solved] [F24] NVENC not working (anymore?)

[sc0repi0]

Hi everyone,

I recently made a little pause recording and came back to a problem which seems to be new, since I never tried to use different capture options. If I now try to start recording, OBS will error out with the following.

(This is taken directly from cli, after looking at the log files, this should be the same output)

I tried to rebuild it from git, which also errored out with:

cmake -DUNIX_STRUCTURE=1 ..
-- OBS_VERSION: 0.15.4-50-g001f3c7

Any ideas? Thanks in advance!

I solved my issue, at least the first one. The problem was not with OBS, it was ffmpeg not able to find libnvidia-encode.so

sudo ln -s /usr/lib64/libnvidia-encode.so.370.28 /usr/lib64/libnvidia-encode.so

That does the trick. If you have a similar problem, just check your lib64 dir if libnvidia-encode.so has been renamed. Symlink it to libnvidia-encode.so and you'll be fine.
