avireadframe - Grabs and returns a frame from a opened video file or camera (experimental)

Calling Sequence

im = avireadframe(n)

Parameters

• n: The opened video file/camera index.
• im: The returned frame/image. If no frame, return 0.

Description

avireadframe grabs and returns a frame from an opened video file or camera. It can only get the current frame and move to the pointer to the next frame.

Video support for SIVP is only available when SIVP is compiled with OpenCV which support video I/O.

Examples

	
    n = aviopen(SCI+'/contrib/sivp/images/video.avi');
    im = avireadframe(n); //get a frame
    imshow(im);

    avilistopened()
    aviclose(n);

Bugs and Shortcomings

avireadframe can only get the current frame now.
