Long time listener, first time post-er. :) You could just try to cat the framebuffer to a raw file and run that thru imagemagick (or photoshop) to see what's going on.
cat /dev/fb0 > output.raw Of course, if you're doing things thru omxplayer or something else like that, perhaps the framebuffer will not have anything interesting in it. (just tried that here and got a black image). ...hope that's a little helpful to you! Here's a reference that may be helpful (see the last post): http://www.cnx-software.com/2010/07/18/how-to-do-a-framebuffer-screenshot/ --dan On Thursday, October 23, 2014 7:41:39 AM UTC-5, farnsaw wrote: > > Oooh, just found a different article on VNC for the Pi that looks > helpful.
