Guess the colorspace directly in mpcodecs_reconfig_vo(), instead of in set_video_colorspace(). The difference is that the latter function just makes the video filter chain (and VOs) force the detected colorspace, and then throws it away, while the former is a bit more general and central. Not really a big difference and it doesn't matter much in practice, but it guarantees that there is no internal disagreement about the colorspace.
