creating/setting zone with Foscam FI9828PW 1280x720 Ip cam results in duplicate side by side image.



Can't attach a picture here "Sorry, the board attachment quota has been reached" so hopefully you can see this from facebook link...


In my alert emails it happens as well. See above.

Any advice?

Thank you
Ben

this is also preventing any alerts from being generated. anyone?

Looks like your screenshots did attach.
Haven't seen this one before.

What does your event log say for this camera?
Does the resolution in zoneminder for this monitor match exactly the resolution in the camera?
What are (all of) your camera settings? Can you post screenshots?

Oh, and please verify whether or not you are using a release of zoneminder or a development snapshot.

Looks like some weird MPEG error? or possibly a misconfigured decoder? I have seen something like this with bad JPEGs (bad header?) and/or machine with a bad memory module(?).

Might consider running Memtest on the machine for a few hours if you can't trace down the error

Are you using Ffmpeg as the source type? If so, could you try Libvlc. From my experience it works better and its more stable.

Hope it helps,

these are the directions I followed to build it
http://www.zoneminder.com/wiki/index.ph ... e_easy_way
event log lists no errors for this camera
res matches. FPS does not. camera is at 15, zm is at 30. otherwise I get that smudging/ artifacting.
and of course can't upload attachment. hopefully linking from FB works.

Does the live view appear normal or does it look like the screenshots as well?

I have a Foscam 9821 programmed identically to that, which is working great.

Since you are using Ubuntu, that means your system uses libav, rather than ffmpeg, which occasionally causes issues, but if that were the case I'd expect your live view to be corrupted the same as the zone edit screen.

live view is not duplicated.

I tried libvlc but couldn't get it to work.

but I did have to install ffmpeg manually http://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu
so maybe, libvlc is missing?

here's an example of the smudging

Wait, what? So you deviated from the Ubuntu instructions you posted earlier.
What prompted you to do this?

The trouble with doing that is you have a packaged version of ZoneMinder installed on your system. That packaged version of ZoneMinder was built against the specific version of libav, which ships with your version of Ubuntu. The code path for libav & ffmpeg are different in zoneminder. If you install a version of zoneminder built against libav, but then replace libav with ffmpeg, zoneminder is making the wrong function calls. This is not guaranteed to work.

Best case, zoneminder will still work but won't be running as efficient as it could be. Worst case, anything can happen from general weirdness to a complete crash.

yes. ffmpeg was not installed with those instructions. I rebuilt twice, from scratch. All I could find to make this camera work was to install ffmpeg manually. I tried libvlc first and it didn't work.

For the smudging, I had to leave Maximum FPS and AlarmMaximum FPS blank. Set the maximum FPS and the bitrate on the camera side, smudging will improve a lot.
