Hello

openSUSE Tumbleweed
VLC installed from Packman repo.

When playing a video I get an error message and the displayed image is a weird one.

main error: buffer deadlock prevented
gl info: Initialized libplacebo v5.264.1 (API v264)
avcodec info: Using Intel iHD driver for Intel(R) Gen Graphics - 24.4.4 () for hardware decoding

How to send a capture ?

Hi,

have the same problem when try to play videos with VLC. I have no video image, video stream is decoded but 0 video frames is rendered.

MX-23.4_x64 Libretto
VLC 3.0.21 Vetinari (3.0.21-0-gdd8bfdbabe8)

VLC log:

gl info: Initialized libplacebo v4.208.0 (API v208)
avcodec info: Using OpenGL/VAAPI backend for VDPAU for hardware decoding
main error: buffer deadlock prevented

I cleared VLC cache, cfg and reinstal it but it not helped. Any ideas how to fix it?

Uninstall the OpenGL/VAAPI backend for VDPAU.

If it affects mpv too, then it's most likely an issue with your distro or package repo, and not VLC so probably nobody here can help

Hello

I get same message error with video that I can view with mpv.

With VLC, I get only the audio, no picture.

The video is a YouTube video. I downloaded it with "Video download helper". The format is mp4.

No problem with other mp4 videos.
