VideoStreamPlayer is extremely laggy on 3.5(stable)

[hoary mural]

I have a video that runs on 512kbps bitrate, and when running it in godot, I just get extreme lag (this affects audio and video simultaneously).
It's an OGV because I haven't even managed to get a WEBM file to begin playing, just to stay as a black screen.

I think I saw somewhere that godot uses CPU instead of GPU to play videos, but even if this is true, is there anything I can do to solve the issue? (e.g. some setting I have conveniently forgotten to enable or disable?)

Thanks in advance

Ok, I think I've found a workaround. this doesn't solve the issue for OGV, it seems that Godot can't handle OGV, and neither can FFMPEG, but VLC creates 20hr long files when converting to WEBM.

The solution is to use FFMPEG for WEBM and godot runs just fine.
