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.
