Hi Samuirai,

I'm looking to do something similar - power via a small daughterboard with a polyfuse to protect the pi.

Which polyfuse are you using? I was looking at 6V 2A fuses but all I can find are surface mount ones. Are you using something different?

The default permissions on /dev/vchiq only allow a process running as root, or running with group "video" to open it. Make sure whatever user is running omxplayer has permission to open /dev/vchiq.

I would like to make some local modifications to omxplayer (from the source at https://github.com/huceke/omxplayer) and I would like to do the build on my desktop box (Core i7), not on the raspberry pi. I have looked but I cannot find any guide to cross-compiling for the raspberry pi running Raspian...
