[libavg-users] Video Performance

[Ulrich von Zadow]

Hi,

I did some video tests/profiling/optimization together with Thomas  
Schott last week. At last count, I hat 300 videos running here (Core  
i7) at once. Frame size 100x100, each video with an alpha channel. The  
videos were running at 30 Hz and looping, the display updates were  
happening at 60 Hz. Consistently, with just a few frame drops.

If I stop and restart the videos once a second, I can still run a  
hundred of them at once without stuttering. That's two hundred threads  
restarting each second and two hundred frame queues being refilled.

(Thomas is in the process of doing an interactive game that takes  
place in a bloodstream. Each blood cell in the stream is a video and  
everything ties together using box2d, a physics engine. The effects  
are pretty amazing - I'll post a video when it's done.)

Cheers,

   Uli
