instant playback video

I wanted to know if it's possible to create a video for instant playback and then save that as a video file , either on disk or to upload/email somewhere.

I can get screenshots of an opengl view and was thinking I could turn those screenshots into an animated movie and add an audio track. If someone can point me in the right direction, or shoot me down if it's impossible unless you have a phd, I'd appreciate it.

Yes its possible but its going to be extremely slow... you can use Theora to compress the movie (the api are embedded in SIO2)... save all the frame use readpixel and number them like 001, 002 etc... and save them on disk as JPEG or PNG (once again the API are embedded in SIO2) then compress your movie from the frame sequence.

Performance will suck and you would hardly get 15fps but it will work

Good luck!

Hello Mr SIO2,

I'm finally back to looking at this project. The theora library looks like it only supports the theora codec which does not play on the iphone as far as I can tell. I must be missing something - please let me know what your thoughts are.

My thoughts are that you should check tutorial07 and the source of iZenGarden...
