Answer 1

You can try a different FOURCC code. Some of them are not correctly supported by OpenCV, some by the multimedia apps. Having one that works with both OpenCV and your favourite video player is a matter of trial and error.

What you can try: Use VLC (in case you don't alreay use it). It is one of the most robust players out there.

If all you want to do is to display/process a sequence of images in OpenCV as video, you can use an undocumented feature of the VideoCapture: Load a sequence of images.

The example is in C++, but you can easily convert it to C.

// pics are a sequence of Pictures001.jpg, PicturesS002.jpg, etc
cv::VideoCapture cap("path/to/my/Pictures%03d.jpg");

cv::Mat frame;

for(;;)
{
    cap >> frame;
    if(frame.empty())
       break;

    // do some processing
}
