Hacking acceptance of other formats into yuvscaler would be a
major undertaking and that's what I think it would take to avoid
treating all 3 variants of 4:2:0 as being the same thing (which is
100% wrong).
Allright, so you are basically saying that y4mscaler is a requirement for
using MJPEGTools with PAL DV. I tried contacting the author a while ago
and asked if he would like to consider including y4mscaler into MJPEG
Tools. Unfortunately I did not receive any response. Inclusion in MJPEG
Tools would make y4mscaler ( and working with PAL DV in general )
accessible to all Linux users out there. I'd love to see that happen.
Dealing with PALDV (PAL just _had_ to make life complicated by not
using 4:1:1 like NTSC) is a strange beast - not sure how to fix the
problem short of reinventing y4mscaler into yuvscaler.
Yes, that is messy. Just don't claim that NTSC is anything more clean than
PAL is. We PAL guys would NEVER mix progressive, interlaced and telecined
video into a single MPEG2 stream. NTSC just _had_ to make life complicated
by not using (near-)FILM frame rates... ;)
