Motion - Support Question 2006x 09x 01x 154503

* buffer overflow detected *: motion terminated when using %f macro

Question

if you use the %f macro (which expands to the filename of the image / video) then as soon as that event occurs motion exits with the attached error. This is on Fedora Core 5 using an based build of today (01/09/2006) snapshot of the code. I think that this could be related to some of the fixes from for the ffmpeg saving files to .avi and .mpg. Also I think it might well be relivent that this is running on an opteron in x86_64 mode.

Answer

It is difficult to verify this because I do not have a 64 bit OS, I do not have an opteron either.

This has been open since Sep 2006 so I have to close it unanswered.

Reopen if anyone has something new to add.
