I think the problem is that VIDEO_PALETTE_YUV420 doesn't correspond to a 
depth of 24. The depth should be set to 12.

Incidentally, does anybody know why the "depth" field exists? Is it for 
unusual formats, e.g. YUV 4:2:0 with 4 bits of Y and 2 bits of UV per 
pixel? It just seems like needless complication of the API to me.
