The earlier version had three deficits: 1. It allowed to set the stream to RGB although this is not allowed when the profile is 0 or 2. 2. If it set the stream to RGB, then it did not automatically set the range to full range; the result was that one got a warning every time a frame with color_config element was processed if the frame originally had TV range and the user didn't explicitly choose PC range. Now one gets only one warning in such a situation. 3. Intra-only frames in profile 0 are automatically BT.601, but if the user wished another color space, he was not informed about his wishes being unfulfillable. The commit also improves the documentation about this. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
