Linux does not play well with media - many say. And they are right, especially with Fedora and NVIDIA :blobcatfacepalm:

First, @fedora does not ship media codecs patented in US - you have to install them from RPM Fusion.

When that is done, another issue to tackle is proprietary :nvidia: drivers works only with X11 which you have to choose when starting desktop session.

Now you may enjoy VLC, which works surprisingly well even from :fedora: repository :blobcatcheer:

But if you want to play HDR10 videos, you may want to come back to mpv, which for whatever reason kept stuttering on my machine :blobCat_nom_wire:

By the way, mpv now encourages nvdec over vaapi for hardware decoding, since it seems NVIDIA somewhat abandoned VA API development (as mentioned in mpv's issue tracker). Still, switching to hwdec=nvdec did not seem to help with video stutter, even though such effect is usually indicating lack of hardware acceleration.

After some tinkering I figured it was this configuration item that caused it (not video, but audio!):

I used this parameter for years to pass-through raw audio via optical S/PDIF port to home audio system.

Surprisingly, removing ac3, fixed the problem - no more video stuttering, so I can either run mpv directly or use it from skin like SMPlayer :blobcataww:

I can only guess this may have to do with Fedora's move to Pipewire, which I have complaned about earlier :blobcatthinkowo:

Yes, it's always fun with Linux :linux: But eventually things work, leaving you learned a new thing or two about computers :blobcatthumbsup:
