we did a Videowall with 6 Beagleboards some time ago.

the hardware is here: http://www.flickr.com/photos/av500/sets/72157622794548090/

and the software running was omapfbplay: http://git.mansr.com/?p=omapfbplay;a=summary

omapfbplay has a netsync option to synchronize the master and the slaves

we used libav for decoding, but omapfbplay also has a libdce backend for OMAP4.
The libdce stuff would need to be adapted to the current libdce though and to
a different displaysink than v4l2...

Regards,

Vladimir
