Hai, I have a video which is having yuv color space and H264 codec. I am using Opencv videocapture function to read a frame. I just want to know whether the frame's mat object is in BGR or YUV color space pixels ?

Thanks in advance.....

VideoCapture will convert the image automatically to BGR colorspace.

you can disable this conversion (and receive YUV) by setting the CAP_PROP_CONVERT_RGB property to false.
