BQL examples

Capturing frames from a video file

apturing
TE PAUSED SOURCE camera1_avi TYPE opencv_capture_from_uri WITH
uri="video/camera1.avi",
frame_skip=4, next_frame_error=false;

This source will start generating a stream from “video/camera1.avi” after executing RESUME query.

ME SOURCE camera1_avi;

Note that PAUSED should not be specified when capturing from a webcam, which keeps generating a video stream.
