[Resolved] After updating through both APT and the Software Store, I can't play mp4 videos with VLC anymore. The screen goes blank for a second or two then the audio starts playing without the video..

I'm using Debian 12, Ryzen 7 5700X processor, and Radeon HD 5450 graphics card. I have tried uninstalling and reinstalling VLC but it didn't resolve the issue. Here's an excerpt from the VLC's log file:

glconv_vaapi_x11 error: vaDeriveImage: operation failed

main error: video output creation failed

main error: failed to create video output

avcodec info: Using G3DVL VDPAU Driver Shared Library version 1.0 for hardware decoding

How do I resolve this issue?

Can you turn off hardware decoding and see if it works then?

I disabled hardware acceleration and VLC is able to play mp4 files again; however, is there a way to turn on hardware acceleration without getting these errors?

Update:

Changing “Hardware-accelerated decoding” to “VA-API video decoder” fixed the issue. Now VLC is able to play mp4 files with hardware acceleration without any issues.

I'm not sure off-hand since I'm not too familiar with VLC.

I would imagine it could be an issue in a graphics driver at the kernel (amdgpu?) or user level (mesa?). It could also be a problem in something higher up.

I would recommend posting an issue in the VLC repo and see if you can get better support that way.
