This does the trick. Would you happen to know why the resultant yuv mat looks like the Y' and maybe the U components are missing?

cv::Mat input_image = cv::imread("CustomInput.jpg"); cv::Mat output_image; cv::cvtColor(input_image, output_image, CV_BGR2YUV); cv::imwrite("/home/nmenne/hri/trunk/dsat/dsat_lsa/CustomOutput.jpg", output_image);

YUV420 would be the desired constant, i think.

Do you know where this is documented? The cvtColor documentation doesn't have any of the YUV options listed.

Thanks to berak's answer I've been able to get something going with OpenCV that uses much less code than the FFmpeg equivalent.

My new problem is that the resultant YUV image doesn't look correct. Following tutorials for saving/showing the image, it looks like the Y and/or U component are missing.

Both images: Original first, YUV second
