Blank video on linux under wayland on h264 sources
On Arch Linux, with both the aegisub package from the official repositories and aegisub-ttools-meson-git from aur I get a blank box when opening a mkv file with h264 video if I run aegisub on wayland. I didn't have any other formats to check if ti was only a h264 issue.
With env GDK_BACKEND=x11 aegisub it works as intended.
The line D 01:21:40 91190273 <manager/video/provider> [../src/video_provider_manager.cpp:GetProvider:94] YUV4MPEG: video is not in a supported format. is what makes me think it could be limited to certain formats
I'm not sure if this was the right place to report this
This is a known issue that OpenGL/GLX does not work on Wayland. The original package in Aegisub already adds the GDK_BACKEND=x11 when launching.
