SMPlayer Support Forum

What Linux distro are you using?

Arch.

Can you send the mplayer log (menu View) after playing a video? I just want to know which video output is mplayer using.

Logs: https://pastebin.com/raw/HW6Yu6eV

This is the default (I removed the config directory and run smplayer for the first time, so it's using mpv).

BTW, when starting from the console, it says: "Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway." If I do as the message says, it gives me this error: https://pastebin.com/raw/7bhbbRpk

(EDIT: previous edit removed, I was inadvertently testing with mplayer instead of mpv)

According to the log, mplayer is using xv. Isn't this video output available in mpv? Doesn't it work?

Yes, it's available. I've tried it and it works!
Thanks.
