I read the source code of smartyuv. It seems that there is no operation on
U and V. I think, only for this filter if I input YV12 instead of I420,
the output will be not influenced, it will be still YV12, won't it? And if
I get a player after the filter and it can accept YV12, it will show the
right effect, won't it?

YV12 is I420 with U and V plane swapped.
The following are synonims: YV12 and YVU420P; I420 and YUV420P.
Both of them are YUV planar colorspaces with chroma 4:2:0 subsampling.
(see http://www.fourcc.org/yuv.php for further reference).
In other words: if you intermix YV12 and I420 you I'll end up with blue
faces. In transcode 1.0.x, default is YV12 and there is a fair amount of
mess into core/modules; in 1.1.x and HEAD, default is I420 and the mess
is almost enterely solved.
