ios - rtsp

edit

Any pointers on how to capture an rtsp stream under iOS? The example tutorial works great capturing from the built-in cameras, but any pointers on where to look to capture other streams?

Thanks

EDIT:

both

CvCapture *camera = cvCaptureFromFile("rtsp://184.72.239.149/vod/mp4:BigBuckBunny_115k.mov");

and

_videoCapture = new cv::VideoCapture;
_videoCapture->open("rtsp://184.72.239.149/vod/mp4:BigBuckBunny_115k.mov");

fail.

I can show that stream using ffmpeg.

Thanks again.

EDIT 2:

I'm wondering now if I have a version of opencv without ffmpeg compiled in, which I'm reading is required for opencv on ios to read streams. Any pointers on how I can test that opencv has ffmpeg?

Thanks again.
