Stuck with --from_video option

[elvis-kture]

I am trying to use this script with --from_video option and my video, but script stucks after "Video [MY_VIDEO_URL] closed."

Does anyone have the same? Where a problem could be? Thanks!

Hi!

I was having the same issue and for me it solved as follows.

I had a video 200x200 (widthxheight) at 1 fps and the program always stopped at "video closed" . Then I changed the video to 720x480 at 20 fps and now the elg_demo.py --from_video argument works. I hope it helps you. This is the VideoWriter object with the codec:

out = cv2.VideoWriter('webcam_video.avi', cv2.VideoWriter_fourcc(*'DIVX'), 20.0, (720, 480))

I think there migth be a problem with the video you are using, maybe the resolution or the fps.

@MellyGray Great thanks! yes, it helps. But would be great to understand the root cause of that problem to have the ability to recognize any video with any fps and resolution.
