Ask the omxplayer folks (popcornmix in particular).

What means 'synced'? Frame synced i.e. or ???
write a script which starts two omxplayers, each of them writing to another HDMI (HDMI0=2, HDMI1=7)

Code: Select all

omxplayer --display=4 --win "0 0 800 480" /home/pi/Videos/trailer_1080p.mov
omxplayer --display=7 --win "0 0 1280 1024" /home/pi/Videos/trailer_1080p.mov
This also uses window mode to play video in a paricular area of the screens.Then see if this is 'synced' enough.
