Encountering a bug in OpenCV wrapper where special characters in filenames (like the 🔥 emoji) result in frame rate and frame count being returned as 0.
Environment
win11, last opencvsharp version
What did you do when you faced the problem?
Attempted to open and process a video file with a filename containing special characters (e.g., emojis).
Example code:
using (var videoCapture = new VideoCapture())
{
videoCapture.Open(mediaFile); // Replace with your file path
Mat mat = new Mat();
videoCapture.Read(mat);
double frameCount = videoCapture.Get(VideoCaptureProperties.FrameCount);
double frameRate = videoCapture.Get(VideoCaptureProperties.Fps);
double duration = frameCount / frameRate;
if (frameCount == 1)
{
duration = 10800; // For images
}
return duration;
}
Output:
Frame Rate: 0
Frame Count: 0
What did you intend to be?
Expected the correct frame rate and frame count, irrespective of special characters in the filename. Currently, it seems that special characters cause these values to be incorrectly returned as 0.
