Video Lan Client (VLC) Use

HDR Too Dark

The default tone mapping for HDR “Hable” is too dark, tried “Reinhard”:

Preferences -> All -> Video -> Output modules -> OpenGL -> Tone mapping -> Tone-mapping algorithm = Reinhard (simple non-linear)

Did not really work for me.

Does not seem to be supported?

RTSP Support

vlc in some distros is packed without RTSP support due to a license issue.

Use snap instead:

sudo apt purge -y vlc
snap install vlc
