Theora 1.0 ?
Hi,
Thanks for your outstanding work.
I'm currently looking for a workaround to the "fullscreen only" ability of the iphone media player. I definitely need to play a smooth video in a view.
When I discovered that Theora was included in your SDK, I was in heaven... until I tried to play some of my videos : it is much much too slow : 256 * 128 at 10 fps is the best I can get.
I tried to encode at different qualities, bitrates, keyframe intervals.
I don't know whether there is a room for optimization in Theora for iPhone. Ideally, I'd like to play fullscreen at 25fps, but 256*128 at 25fps would look acceptable with some upscaling.
Anyway, Theora 1.0 was just released and claims to be CPU friendly. It looks like you use a much older version.
Do you think it would be worth using the latest ?
Cheers,
Dominique.

Re: Theora 1.0 ?
I integrate the new theora lib this morning, I do see some performance gain, however I didn't have time to extend the tests to far. But I can send you the current source code if you want to do further test and maybe include some optimization tweak or something lemme know...
Cheers,

gimme gimme gimme !
Not sure about my ability to optimize anything, though. I know objective-c / cocoa quite well, but I'm new to opengl and low level libraries !
