Recently on the mplayer lists the topic of chroma from bttv in 4:2:0 mode. At least in the past it has been true that since the Bt878 has no true downsampling 4:2:0 mode that the bttv driver only gives chroma from the top field. Is this still true? Since this is really a hardware limitation of the chip, we really think that bttv should stop supporting 4:2:0 formats completely, and instead only provide 4:2:2, since that's all it really supports [1]. It would make things a lot easier, clearer and more correct. Thoughts? -Billy [1] http://mplayerhq.hu/pipermail/mplayer-dev-eng/2003-December/022612.html
