Did you follow the build steps exactly as described on the DarkMark page? Or did you attempt to build OpenCV yourself?

If OpenCV was installed correctly, then my next guess is the video file you are attempting to open is corrupted. DarkMark doesn't process the video directly, it uses OpenCV to handle all video input/output.

I would try to use another tool (VLC, Handbrake, Youtube) to convert the video file to another format, and try again. If DarkMark does this with all videos, then the problem is your copy of OpenCV. If DarkMark can open other video files correctly, then the problem is with the video file.

I followed build steps exactly, i didnt build OpenCV This problem with all video What version of OpenCV is needed for DarkMark? My OpenCV is 4.5.1

stephanecharette commented 3 years ago

DarkMark requires OpenCV v2.x or newer.

stephanecharette commented 3 years ago

What operating system and version are you using? And can you share the video so I can try it out?

When I look at my various systems where I run DarkMark:

On my newer Ubuntu 21.04 which uses the same version of OpenCV as you, I just tested it now with some video files I have and it worked as expected:

I removed OpenCV 4.5.1 and install 4.2.0, then built darknet, Darkhelp, DarkMark and it's work! Thank you!
