Cannot view events that have only 1 alarmed frame

[vertigeaux]

If an event has 2 or more alarm frames, it plays back fine, but if there is only 1 alarm frame I get the "broken image" image. The images exist on the hard drive, and I can even click the "Frames" link and view each frame individually. The event just won't play back.

Possibly related, I cannot view the "Stills" for any event, regardless of the number of alarmed frames. In this case I don't get the "broken" image, I just get the controls with a blank space where the images should be.

When I click an event that has only 1 alarm frame, I get this in the log:

Executing the addr2line command returns an unhelpful series of ??:0.


Other information that is probably helpful is I am running on Ubuntu 12.04. I had to jump through some hoops to get apache, php, and zm updated, but all appears well except for this issue.

After some fiddling, I think I have discovered that the key is not 1 alarm frame, but a total frame count of 11. I had my pre- and post- frame counts set to 5, and every time there was 1 alarm frame (total 11 frames) I could not view the replay. However, setting the pre- and post- frames to 6 (total of 13 frames), or 4 (total 9 frames), or 5 and 4 (total 10 frames), I could view the events just fine with no errors in the log. When I set them to 6 and 4, again for a total of 11 frames, I cannot view the stream.

Does anyone else have trouble viewing events consisting of 11 frames? Or is it something weird with my setup and I should just set my pre/post frames higher and forget about it?
