I am trying to read a video with OpenCV after I downloaded with youtube-dl, all this on conda enviroment. But always it shows me " Error opening video stream or file". After of looking for a solution, I found many, i.e. ffmpeg support is not available then I tried but it does not work. Maybe there is other solution to read video from OpenCV, I am working with conda enviroment.
