Hi, i have built the sample app opencv_interactive-calibration.exe and it will run ok on a webcam (although every frame is rejected, I assume the webcam is too low res)

I have a higher resolution video that i am trying to run, but when i run:

opencv_interactive-calibration.exe -v bmCalib.mov

in a cmd prompt, I get:

Hot keys:
esc - exit application
s - save current data to .xml file
r - delete last frame
u - enable/disable applying undistortion
d - delete all frames
v - switch visualization
Unable to open video source

The mov is in the same folder as the exe. i have tried converting to an avi, and I get the same issue. Can anyone help me out here?

Thanks!

try: -v=bmCalib.mov (the = is important, similar for all other cmdline params)

Ah sorry, I mean that it just returns Unable to open video source.

Ah, I had openCv built without ffmpeg support. Never noticed before because I always used image sequences! rebuilding all libs with ffmpeg has solved this. Thank you for your time.
