I'm not an user of the filter, so can't say even what is useful
for. Can someone comment on it?
Is it possible emulate it with the native filters?
When interlaced video is stored in YUV 4:2:0 formats, chroma
interlacing does not line up properly due to vertical downsampling
of the chroma channels. This filter packs the planar 4:2:0 data
into YUY2 (4:2:2) format with the chroma lines in their proper
locations, so that in any given scanline, the luma and chroma data
both come from the same field.
Select the sampling mode.
0: nearest-neighbor sampling, fast but incorrect
1: linear interpolation (default)
