Can't Export Video

mikesjays · Post by **mikesjays** » Sun Aug 17, 2008 4:24 pm

I was wondering if someone can point me in the right direction on how to figure out why I can't export video.

I'm running FC8 and I have no problems watching video on the web interface.

When I try to export as a tar there is nothing to open. When I try as zip I just get export faild?

Sure. Something went wrong.

So want to give us the errors, or logs, and how you installed ZoneMinder?

This suggests that the named symlinks for the MonitorIDs are missing.
Recreate the symlinks so that the path exists and that should solve your problem.

Can you tell me how to do that or send me to the right place to get the info?

Thank you

Create symlinks in you events folder that are the name of your cam to the monitor id of the same cam.

ln -s [monitorID] [CamName]

ie.
So if I have a cam named "FrontDoor" and it has a monitor ID of "3"
cd /some/path/to/your/events/directory
ln -s 3 FrontDoor

Cool I did what you said:

Code: Select all

[root@vserver ~]# cd /var/www/html/zm/events/
[root@vserver events]# ln -s 1 108_5th_Ave

Now I get the pics but there is no video, is there something else I have to do to get the video?

Video is only available if you have ffmpeg or the other encoder installed and you have created videos for the event. The export feature does not create videos for you.

I do have ffmpg installed is there a way to go back and recreate video for an event that already happened?

View the event you want video of, click the "video" link above the event video window, the rest should be self explanatory.

If you have the images, you can use ffmpeg from the command line to generate a movie as well.
