FOSDEM 2010 is over, and I’d like to call it a success for FFmpeg. The 11-man strong delegation showed the stunned audience a smashing demo featuring a Beagle-powered video wall. It looked like this:
The people who pulled this off look like this:

I recognize you and Attila in that picture and that’s about it. Have we seen that much turnover in regular FFmpeg contributors?
The one with the silly cap and the bag is me ;)
To the right/behind there’s Luca (Barbato) and to the right Reinhard (siretart), and further right the
OtherFirst Diego.I didn’t realise the guy from Clerks was an ffmpeg committer!
This looks interesting… Are there some details around about it? I have a beagle, I hacked gentoo on it, and ffmpeg too (with my stupid questions on BB mailing list), and it’s nowhere near 1080p… 480p maybe (no DSP). :) So how does it work?
There are six beagles driving those displays.
any more information on howto setup a similar presentation? were you using the DMX protocol of X11?
Split the video in six parts, play each part on the corresponding Beagle using something with sync capability. I used omapfbplay.

Hey Mike,
there must also be other reasons for you not recognizing people, like fading memory. I know that there are three more people that you have met on Linuxtag 2007 in that picture, so you have some chance of recognizing (I won’t tell names). Apart from that, it depends on your definition of regular contributors :)
But hey, we managed to get a GIRL in the picture :)

What’s the maximum resolution you can achieve per board? Is there a limit regarding the duration of the video?
Will you post your code?
Regards
We’ve run it at resolutions up to 900×720 per board, which worked well. The video length is only limited by the space on the SD card. The playback is done with omapfbplay.
Thanks for your fast answer…Great work! how do you sync the videos? Could you explain me a little bit?
Regards
