Need to record video with a DSLR using an SDK

I want to be able t开发者_JAVA百科o control a DSLR camera to start/stop recording video.

Canon has a nice SDK, but it seems that Video capture is not supported.

Anyone know if Nikon SDK supports this ?

Maybe there is a workaround for shooting video using Canon's SDK ?

Thanks.

Another hack: you might be able to capture the liveview images and stitch them together into a movie file.

It seems this is impossible using Canon's SDK. I solved this with a hack - using a USB-IR transmitter that sends the signal used by a Canon Remote to start/stop video. Ugly but works.
