I'm using OpenCV 2.4.8 on Ubuntu 14.04 to read in some MP4 videos. The program works on Macs and other Linux machines, but for some reason when I compile and run the program it gives me these errors before exiting:

The main parts of the code that are reading in the files look like this (they're split between some methods so I've included the lines that do all the work to do with opening and reading the frames:

cv::VideoCapture cap; cap.open (input_path); success = cap.read (data.frames[i]);

Does anyone know how I can get my program to correctly read in these videos? I tried to add "cap.set(CV_CAP_PROP_FOURCC, CV_FOURCC('H', '2', '6', '4'));" before "cap.open" but that didn't seem to work.
