If I capture a frame and then write it to JPG, like this:
VideoCapture capture = VideoCapture(0); capture.read(frame); imwrite("frame.jpg", frame);
ImageMagick identify says frame.jpg is Colorspace: sRGB.
I made this experiment because I read that OpenCV's default is BGR, not RGB.
Can I use CV_RGB2GRAY in cvtColor? Is RGB OpenCV's default?

ImageMagick ImageMagick's identify says frame.jpg is Colorspace: sRGB.
I made this experiment because I read that OpenCV's default is BGR, not RGB.RGB. But it seems to produce RGB JPG files.
Can I use CV_RGB2GRAY in cvtColor? cvtColor always and be safe? Is RGB OpenCV's default?
