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?
Glad you got it resolved. FWIW This problem should have affected practically all video playback and not just mp4, so adding that part in and then trying to find reasons why ONLY mp4 wouldn’t work… doesn’t get someone very far in helping you :)
