Play one Video on Raspberry PI 4 DUAL HDMI

Tue Dec 24, 2019 9:20 am

I have been working with raspberry pi since the pi 2 , The dual Hdmi output on the pi 4 is an awsome feature, except that there is no lead to how to configure the 2 seperate desktops of the 2 Hdmi's into an extended one ,
I want to use OmXplayer to display one video with both HDMI 0 and 1.
Is there any solution for this?

OMXplayer can only display on one output at a time. VLC should be able to play over both displays I think... Set up the displays using the display configuration tool in the menus.

One DIY-ish way to do it is just to duplicate the HDMI output using one of these:

omxplayer can't do that, as this requires code to duplicate the decoded video frames into two and send each to one display. I don't think there's any software except my info-beamer pi tool that supports that at the moment.
