Fix for montage view camera freezes
Posted: Wed Sep 09, 2009 11:39 am
by yanychar
When a stream socket is closed on the server, the picture freezes. The patch installs an onLoad listener for each camera in montage view and launches a checker. The latter examines the latest load time for each picture and re-queries the stream, if necessary.

I did get it fast enough. The patch was not complete. Corrected version follows.

hey yanychar,
I know this is a path for zoneminder in the montage view. And I think its php.
so my question is ... how do I apply it

I think... you need to save the code to "patch-file-name" in ZoneMinder-1.24.2/web/skins/classic/views/js folder then run this command
patch -p0 < patch-file-name
or maybe just save the file in ZoneMinder-1.24.2 source and apply it... and recompile and reinstall, if you didn't compile the source yourself it is useless...

I modified the path in the patch to be correct on my install but I get
root@zoneminder1:/usr/share/zoneminder/skins/inferno/views/js# patch -p0 < patch.txt
patching file b/montage.js
