BTW. If xawtv expects 4:2:2 (packed) and the > driver is only producing 4:2:2 interleaved this is probably why? The formats for YUV data are usually called packed and planar. You could also call the packed format interleaved. If you tried to treat planar data as packed or vice versa it would just not work, your image would be more or less totally screwed up. The blue tone you see might be the result of a different YUV color spaces. Unfortunately, people use YUV to refer to more than one different color space. For instance the YUV data from the bt848 isn't exactly the same as the YUV colorspace used in JPEG files. If you make a JPEG file using the YUV data from a bt848, or probably any other TV based capture card, the image looks wrong. I don't remember exactly, but I think it comes out too green.
