ZMS terminates when attempting to change scale from "Ac

[krisp]

I'm having an issue while using the monitor stream and changing the scale of the jpeg stream on the fly. If I set the default scale to 2x it will load up fine at 2x, but can't be switched back to actual. Here is the debug log from zms:

It briefly shows the image as 2x in Firefox or IE and then the image disappears and I have to reopen the monitor window.

I get the same issues with a installation freshly upgrade to 1.24.1. It happens with two different IP-Cams and by scaling the resolution in either direction.

When I set the default scale of the camera to some none standard values, than this scale works without problems. But I try than to change the scale from default (1/2 as example) to original, zms crashes with the messages reported by krisp...

Any tips how to further trace this problem?

I have seen this as well, and know that it has been discussed, I'm thinking it's fixed in SVN but don't remember for sure. I'll take a look at it this weekend so long as I remember

I have always prefered to use the client side solution; by that i mean using the firefox zoom ("ctrl +", "ctrl zero" or "ctrl -") to zoom in/out; works perfectly with images and video live streams;

of course it is not a solution, and neither a part of it, but it´s a way to get the same results in terms of quality, and i think much more practical because it feels MORE "on-the-fly" that changing the scale on a drop-down with the mouse and waiting for the "server-side" effect; it would be exagerated to say that this "lowers" server load, but theoretically, i think it does;

And just before someone says that the quality is not the same, please make a test first and tell me sincerely you notice some quality loss, i really doubt it;

disconsider this suggestion if you´re more interested in caving and fixing the real problem, tough;

This is a new 'feature' of FireFox 3 at least. It objects to the image size in a stream changing on the fly. It used to work in FireFox 2 which didn't mind.

The released 1.24.x versions of ZM dynamically adjust the resolution for best results. Ie, if you are viewing at 50% resolution and then resize to 100% then the resolution you see on your screen would have changed to match. In order to get round this issue the SVN version of ZM is changed now to just adjust the client window and the stream continues at the initial resolution so in the example above if you go from 50% to 100% scaling then all you will get is a doubled up 50% size image with no improvement in resolution unfortunately.
