Interesting! I also am seeing a segfault in y4mstabilizer. Had
a VHS tape that was a little unstable (shakey in the vertical
direction - tape jitter, etc) - no where near 200 pixels though.
After 41 frames of still (black screen leadin) y4mstabilizer segfaults
on the first non-black frame. Even more strangely this only seems
to happen on PPC based systems, on a AMD64 system no segfault. I've
saved a 500 frame sample which triggers the behaviour - maybe when I
get back from vacation I'll have time to poke around in the code (the
area of segfault is in the gmotion() routine it seems).
Cheers,
