Hi,
I don't know about the state of pd/gem on raspi these days, but some years back I had to synch and control multiple video projections using raspi3's for a performance (with some diy servo shutter for the video projectors), and finally used omxplayer (on the framebuffer directly) and python with OSC control, as it was precise to the frame - the whole was controlled by a puredata timeline sending command by OSC to make loops, pause, jumps in the videos ... it worked nicely for days ;)
you can find the messy code here : https://framagit.org/Olm-e/osc-omxplayer (probably to revise with current python/omxplayer)
In this it does not support 2 screens directly (raspi3 has only 1), but omxplayer seems to support it so it's probably a matter of passing the good arguments to it (--display=2 and --display=7 )
hope it helps ;)

Hi list,
Has somebody used the two HDMI outs from PD to play two videos on two different screens?
I am finding infos from people doing it with omxplayer, but I need it synced and looped. Or are there any other Linux video players that can sync two streams on two different monitors?
