How to record gameplay while on device?

[GMac]

I need to record the output of gameplay while playing on the device and not on the simulator. Does anyone have a recommendation on how to record it?

Thanks!

You cant capture the screen play directly from the phone.
You have two choices; One is screen capture the simulator. Option two is use a video camera to record the device.

Thanks for the note.

Sorry to hijack your thread, but I have a similar problem and didn't see the need to start another thread. I too need to record gameplay.

The problem I have is that my game uses the accelerometer to control the character and so capturing the simulator screen is not really suitable as there is no way to simulate tilting, and using a video camera gives rather poor results.

I did try Acc-Sim (details here : Brian Pratt's Homepage - AccSim iPhone App) , which is an opensource project that allows you to control the accelerometer values in real time on your device while the game plays out on the simulator but unfortunately, while this worked, the movement of the character was far too jerky and so this method was unusable too

If anyone has any other ideas on how to capture gameplay on an iPhone with a game that requires an accelerometer, I would really appreciate your input. Perhaps video camera is the only way.

Many thanks,

Dave.

Actually, Acc-Sim seems to be working ok now, must have been a network glitch!

If you're using OpenGL, you could render everything to a full screen texture and then save it to a file and then render that texture to the screen before deallocating it and rendering the next frame to a texture. This will be really slow though.

EDIT:
To save it as a video you'll have to look up how to encode the data. Either that or you could write a header to the beginning of the file with stuff like dimensions, bytes per pixel, and frame count. Then write all the image data. And on your computer you could write a player that will read these files and play them back.
