Maximum quality of video with Flex AIR

I want to use a camera which is installed in my computer in a Flex AIR application i'm writing, and I have few questions regarding the quality options :

1. Do I have any limitation on the video image quality? If my camera supports HD recording, will I be able to record in HD format via the AIR application?

2. How can I export the recorded 开发者_如何学运维video in any format I want?

3. If I want to use the same camera for shooting stills, how can I ensure (within the code) the best quality for the result pictures ?

Thanks for your answers.

1) Air can play 1080p no prob, however it cannot 'record' it from the application. There are some workarounds but you won't have sound. This is something that the OS should handle.

2) You can't, see above.

3) Shooting stills with a camera for picture quality is done on the hardware side, not software. In the software, it would essentially be equal to just taking one frame out of the video.
