Running Zoneminder v1.22.3 on Gentoo 2007.0 (current).

When viewing a (any of 3) monitor with Firefox and changing the Scale (menu) setting from Actual to anything above x1.5 causes segfault for ZMS.

ZM_STREAM_METHOD = jpeg

Code: Select all

Couldn't find anything describing this in forums/faqs/etc.
Nor other errors in logs.

Changing the view scale back below x1.5 works normally after segfault, probably because the page/process gets reloaded.

Actually the Monitor has one zone, and the zone is working.

I'm having the same problem and haven't found a cure. Did you resolve the problem? If so, how? Thanks
