when i click on my cam in the console, i see the picture. If i try a different scale, i get a new resized picture, and when i go back to a previous seen size, i get a broken gif.
I need to stop zm, close my browser and restart everything to be able to view a picture again... same with cambozola, does not work in a consistent manner.

I'm running Fedora core 1, client running mozilla / IE .

Any ideas ?

Hi,

This error is discussed in the FAQ.

Cheers,

I've not seen this message since I patched zm_local_camera.cpp to add one line after line 87:

Code: Select all

        vid_win.x = 0;
        vid_win.y = 0;
        vid_win.width = width;
        vid_win.height = height;
+       vid_win.flags = 0;

        if ( ioctl( m_videohandle, VIDIOCSWIN, &vid_win ) < 0 )

I suspect the critical bit might be that the VIDEO_WINDOW_INTERLACE flag bit is reset.

Great! No more errors.

No more log errors but my original problem still remains.

Yep, the "Failed to set window attributes" message is not related to the scale change problem.

There's definitely something going wrong when using the pop-up in the Watch window to change the scale of the viewed image with jpeg streaming. The first scale change works. After the second scale change I start getting a "cannot be displayed because it contains errors" message in the browser. It seems to need both a ZoneMinder restart and a browser re-start to cure the problem... ...I think...

Problem is with scale change in watch window...
