LibVLCShrap can't not use opengl win32 video output in Avalonia application

ASS subtitles are all black (unreadable) with VLC 3.0.8 and newer

This problems is also occur in LibVLCSharp. So I want to solve this problem by switching the video output to OpenGL(win32) by using advance command-line --vout=glwin32 when new a LibVlC instance in code, such as var _libVlc = new LibVLC("--vout=glwin32");.

But I found that it can't switch successfully when the media player binding to a Videoview control in axmal. With Binding

When the media player playing video with no binding, it will create a new window automatically, in this case it work. Without Binding

Is there any workrounds to fix this? Thank for any help.

Unfortunately, you can't do that. The Avalonia control is implemented by using the set_hwnd function, that internally forces the use of d3d11.

If you wanted to use opengl instead, you would need libvlc4 hw-accelerated callbacks, and a lot of manual work...

I'd prefer to submit a bug on VLC if it does not already exist and wait for it to be fixed.
