Video Acceleration support for H264?

[amininger]

I just installed a fresh copy of the minimal Manjaro distribution on a Thinkpad T14s with an AMD Ryzen 7 PRO with Radeon 680M integrated graphics.

I’m looking into video hardware acceleration, and it doesn’t seem like H264 decoding is supported. Is this normal for this kind of graphics? Or is there a way for me to install support for it?

Thank you kind stranger, that totally worked!

(I reinstalled both libva-mesa-driver and mesa-vdpau to apply the alternative drivers)

Be careful not to get in trouble. It looks like mesa-nonfree is no longer supported for stable branch .
for comparison:

• Files · 23.0.x · Packages / Extra / mesa · GitLab
• Packages mesa, branch compare

Sad to see this, but better compile it yourself. Your thinkpad is able to do this in less than 10 minutes. Sorry for those with weaker hardware.
