Description

VLC has a built in --fullscreen argument for auto opening in fullscreen mode. But when using --player-args "--fullscreen", vlc will open, but it does not play the stream. Just goes to default playlist window.

Expected / Actual behavior

VLC should open streams in fullscreen mode when '--fullscreen' is set as an argument.

Setting '--fullscreen' as an argument causes the stream to not open at all. Just VLC to the default window.

Reproduction steps / Explicit stream URLs to test

1. run streamlink --player-args "--fullscreen" <streamurl> best

Log output

>streamlink --player-args "--fullscreen" <streamurl> best
