I have a problem with VLC on three projectors. I want to play one video on two side projectors and second one on main projector. Here is my command (Windows 10):

Code: Select all

"c:\Program Files\VideoLAN\VLC\vlc.exe" -f side.mp4 --qt-fullscreen-screennumber=2 --no-one-instance && "c:\Program Files\VideoLAN\VLC\vlc.exe" -f side.mp4 --qt-fullscreen-screennumber=1 --no-one-instance && "c:\Program Files\VideoLAN\VLC\vlc.exe" -f main.mp4 --qt-fullscreen-screennumber=3 --no-one-instance

And generally, it's OK. VLC instances plays three separate videos on selected projectors, but the problem is in out of sync between side projectors. Main video may play with one or two seconds latency, but side projectors must be synchronized.

How to get one VLC instance on two side projectors, and the second on main projector?

You may try to use the netsync module https://wiki.videolan.org/Documentation ... s/netsync/

Maybe it worked with input-slave options in old VLC version, but this doesn't seems to be the case anymore, see: https://code.videolan.org/videolan/vlc/-/issues/20167
