+1, same issue using a usb video capture card.
videotest.py is properly reading the frames.

Hi, I am also getting the same error.
Most of the time it still works but when lights start flickering, I try a few more times.
I wonder if it is Video Capture Card related.

Related:

• Can't set Buffersize in opencv 3 opencv/opencv#10671
• Can't Set CV_CAP_PROP_BUFFERSIZE dactylroot/rtsp#13

This is a decent workaround for those interested. I had to change it a little bit to propagate the ret value from self.cap.read(), so that in case of an error the main thread doesn't wait forever.
