Can't make VLC run on my eGPU
Using the proper configuration, and the proper Arch packages, mpv runs just fine on my Arc B580 eGPU. Not VLC though, and I tried both the flatpak, and the pacman versions. Very frustrating. I've looked into using SMPlayer, hence dispense with VLC altogether, but that doesn't seem to be able to use mpv.conf properly. Until SMPlayer fixes that, it looks like I will have to rely on VLC.
So here is what happens: The way that I am trying to force VLC to use my eGPU is by means of switcheroo-control. Used without switcheroo-control, VLC performs without a hitch. When forced to use the eGPU, VLC doesn't show video: screen is solid black (pacman) or green (flatpak). Not sure what I may be doing wrong. I think I got all the required VLC-auxiliary packages installed. Not sure about the settings--most setting are the default ones.
Any opinions?

There's other gui to mpv out there, eg. xt7-player-mpv-git in aur supports most mpv options and you can pass others too.
Help me to improve ssh-rdp !

What do you configure as VLC output?
VAAPI? Automatic? VDPAU??

What GUI anyway? mpv has some decent enough OSD? You just need to keep the manpage open when configuring it

Automatic. Should I use something else? Interestingly, I don't see Vulkan among those options.

Looking for options, among others, to select playback drive (for BD and DVD disks), as well as Chromecasting.

Re: Can't make VLC run on my eGPU
https://man.archlinux.org/man/mpv.1#Disc_Devices
https://github.com/mpv-player/mpv/issues/177 - that's probably not a GUI restriction (assuming your intention isn't to just *play* a cast from somewhere else)
What you're seeing (black/green) is likely the color key for the ouput (VAAP/GL/XV) - see whether any specific output mode (there's probably a software one) does NOT cause this.
Is this on wayland (which compositor) or X11?
For the latter please post the X11 log.
Did you attempt DRI_PRIME and possibly along explicitly setting LIBVA_DRIVER_NAME, https://wiki.archlinux.org/title/Hardwa … ing_VA-API ?
The VLC log might also hold hints as to where the problem is located.
