Comment (by clam):
I just found a workaround completely by chance -_-
The chroma upscale works fine if I call libswscale to activate the
interlaced flag :
d:\ffmpeg\bin\ffmpeg -f mpeg -i bug.vob -vf scale=interl=1 -c:v prores
test.mov
Looks like the interlacing information is lost somewhere between
libavcodec and libswscale.
