Title: 2.8.1 - frame stuck after resume from suspend (sleep)
Post by: rado84 on September 03, 2022, 06:31:29 PM
While extracting screenshots from a video, I accidentally pressed Pause (the key I've set linux to sleep) and when I realized my mistake, I pressed another key to wake the system back up and resumed what I was doing. When I entered a new time point and pressed "OK", the slider went there but the frame didn't change. The frame remained the last one I had extracted. I had to restart the program and reimport the file for the program to work normally.

VDPAU? It is known to not survive suspend. I don't think this is something we can catch. Else please specify which video display you use, thanks.

What do you mean by "video display"?

?? The picture you see when a video is loaded in Avidemux. This picture is painted on the screen using one of video display techniques you choose in Avidemux Preferences. These techniques include an unaccelerated path where the CPU does all the scaling work ("Qt") and a number of hardware accelerated paths like "OpenGL" if the version of the Qt framework used to build Avidemux is not too ancient, and also "VDPAU" and/or "LibVA".

The "VDPAU" video display works in general very well on NVIDIA hardware with the proprietary driver, but it is known to cease operating upon resume from suspend. Probably a graphics card driver issue.
