Help me get nvdec working

Okay, so it happened that I was reinstalling Garuda. Nvdec worked before in mpv, but now it doesn't, and I can't for the life of me remember, what I did before to make it work.
vo=gpu and hwdec=nvdec is added to mpv.conf, but not working.

I have found gstreamer-nvidia in the aur, providing nvdec/nvenc, but that fails to build. I think I need help. :frowning:

gstreamer-nvidia failed to build, but still it's suddenly working? I really don't know what's going on here..
Which logs are you talking about? I didn't have this gstreamer-nvidia package installed before but still it was working.

What @edu4rdshl was referring to was that if you claim a package will not build, then you should include the output so that we can see what errors occurred.

Please post all logs/outputs as text, (not pictures) on the forum. Obviously there is no need to post this now if your issue is resolved.

Thank you for your replies. The issue might be resolved, in that nvdec is now working, the point is that I don't know why. Or if this gstreamer plugin is even the correct way to get nvdec working. I want to make sense of this.

Here's the build log

I am unsure what may have caused those errors, but it might be worth testing an alternate AUR helper. Yay, Trizen, Paru, Pacaur, are all good AUR helpers.

Thank you, I will try and report back.

Edit:
Okay this is a mess. I edited out the offending options, only to have it fail to build later at a dependency for cuda10.1, which I can't build because this depends on gcc8, which also fails in turn.

Does anyone have an idea how to get nvdec working in a dependable manner, repeatedly?

Please report that to the AUR maintainer, the package hasn't been updated since 2020-04-15, there are already comments on why the package is broken but the dev seems to be away or simply ignoring them.

Play a video using verbose option in mpv and paste the log.
For example,

mpv -v video.mp4
