Ok, so I just discovered that yuvmedianfilter has a -I switch for
interlaced inputs (it switches to separate field filtering). This
should probably be in the man page and the -h output, since the effect
of not using it (with interlaced input, of course) is to perform a
(bad) partial deinterlace. The output looks jerky and it doesn't save
any bits either.
Once I used -I I found a bug - -T 0 loses chroma info for the bottom
half (turns it green), while -t 0 loses luma info for the bottom half
(turns it black). This is clearly related to the field-level
processing in the filter. It should be a simple fix, if nobody else
does it I'll send a patch once I get around to it.
