BUG: Segmentation Fault on Size Changes, when Mask Image doesn't fit

Having a mask file of i.e. 640*480 and changing the catpture size to any different size causes the according thread to segv when trying to load the image.

Test case

config:

width 512

height 384

mask file "Image file of a pgm mask of 640*480"

Environment

Motion version:	3.2.3
ffmpeg version:	0.4.9pre1
Shared libraries:	ffmpeg
Server OS:	linux

Follow up

Naturally mask file must be same size as the image size. That is how Motion is designed.

Maybe Motion should report it more elegantly but it should not work with it.

Hmm. Forgot to add a nicer error message to 3.2.4. Will keep this open for 3.2.5.

Not a very important bug I think. There is no plan to make Motion scale mask files.

Fix record

It turned out to be a small syntax error (one % too many) in get_pgm - in a line that prints the error message that caused the seg fault.

The code was all there to report the mask size failure and to continue without the mask.

Fixed SVN 46 / motion-daily 20060223
