about upload iPhone video to Youtube

how to set the video format of the iPhone camera captured? I think that can be mov,mp4, h.2x , because iPhone can play it, but can not find API to set the vid开发者_开发百科eo format to recording .....

also want upload the video to youtube, anyone know where can find a good open source code for this purpose, I think that this feature will be commonly and it must be done by other coder....just want save time for this purpose ..

thanks for your help

use gdata is enough

Using gdata is the way to go as Robin mentioned above. Here is a great article that outlines what you need to do and provides a great set of source code to get you started.

Hope this helps!!
