I tried to copy the steps of previous discussions that had an issue with video decoding but at this point I’m stuck. I was using yt-dlp + mpv to play a video, but it only plays the sound, no video in mpv.
This is the result of mpv -v '【N3】QUARTET Lesson 2 Part 2 ｜ Intermediate Japanese [I-FhbIViHX4].mkv'

The main issue that stood out was:

[vd] Could not open codec.
[vd] Decoder init failed for libopenh264
[vd] Failed to initialize a decoder for codec 'h264'.
It also lists [cplayer] Video: no video
So I tried to rpm-ostree install openh264, but I get this:

The video plays fine in Librewolf, which states that H264 is supported in about:support
I’m unsure of what to do next
