PyQt5 Media Player Won't Render On Ubuntu 22.04

[mike375]

Recently installed Ubuntu 22.04 on a new laptop. I've got a simple Python video app that uses QMediaPlayer. I'm getting the following error in the console: Error: "Internal error: could not render surface" when I open a mp4 file.

Believe I'm running X11; In /etc/gdm3/custom.conf has a line "WaylandEnabled=false".
The Python application runs fine on my old laptop running Ubuntu 20.04.


There are no changes to the program between Ubuntu 20.04 and 22.04.

Googled all around and can't find anything.

I'm not sure if I can help with this, but is this installed?

Description: GStreamer helper programs from the "base" set
 GStreamer is a streaming media framework, based on graphs of filters
 which operate on media data.  Applications using this library can do
 anything from real-time sound processing to playing videos, and just
 about anything else media-related.  Its plugin-based architecture means
 that new data types or processing capabilities can be added simply by
 installing new plug-ins.
 .
 This package contains helper programs from the "base" set, an essential
 exemplary set of elements.

I find mutter a challenge this go round.

Believe I'm running X11;

To be sure, what session type is selected at login?

Error: "Internal error: could not render surface"

I would wonder if running your program with LIBGL_ALWAYS_SOFTWARE=1 environment variable set might make any difference?

Thanks. I'm seeing gstreamer1.0-plugins-base-apps is installed. Might need to go back to 20.04. V
