cpu arch (intel or PPC) has, as it turns out, NOTHING to do with it.
Program would crash on an Intel based MacBookPro. I haven't tested
on other systems BUT I think there would be problems there also.

Not exactly. Or rather, "maybe" ;)
What it needed was a proper declaration of the 'psumsq' (pointer to
the sumsq function). That s

Thanks but as you might have guessed I needed more. Even then it
took a long time to figure out what the problem was.
There were, I think, 2 problems. One is that motionsearch.h is NOT
installed by the mjpegtools installation and this line is needed in
motionsearch_deint.c (where psumsq() is called):
extern int (*psumsq) (uint8_t *blk1, uint8_t *blk2, int rowstride, int hx, int
hy, int h);
But even after doing that there is the same type of error that
was found in yuvdeinterlace.
There is a HUGE difference between:
nframe[0] = buff_offset + (uint8_t *) bufalloc (buff_size);
and
inframe[0] = (uint8_t *) bufalloc (buff_offset + buff_size);
The FIRST one is what was being done. It allocates a buffer of
buff_size bytes and THEN modifies the pointer.
The SECOND line allocates a larger buffer to allow for overshoot
Also, I changed the 'malloc' to be bufalloc() which will allocate
properly aligned buffers (required by MMX and Altivec routines).
Try the attached source kit and see if it works (it should at least
NOT crash ;)).
If it doesn't work then well, try Compressor2 - I'm out of free time
for a few days ;)
