Research direction
No source files or tests are named. Start by reproducing the failure with Wayland enabled, a Raspberry Pi 4, an H.265 MP4, and cvlc after granting video-group access; compare it with Wayland disabled and collect the missing crash logs. Done means the reported segfault is isolated and fixed or narrowed to a specific component.

Description
Describe the bug
Hello all. I have some h265 HVEC encoded mp4 files. VLC attempted software decoding and that didn't go well. I discovered via cvlc that newly created users are not part of the video group. This means I can't write to the dev nodes video or media. Once I added my user, I tried cvlc and it produced a segfault. I turned off wayland and it worked beautifully.
Steps to reproduce the behaviour
Enable wayland, add user to video group, play an h265 file via cvlc. This will segfault.
Device (s)
Raspberry Pi 4 Mod. B
System
Bullseye
