No pictures with zmu loading libavcodec.so

[blacksmith]

Hi, all,
After long traceing, I found my problem with the following message from /var/log/httpd/error_log. So, I don't have any pictures. What should I do?

Looks like you may have a permision problem, but I don't think this would stop you from getting video.
What type of system did you set up?
What versions/distro?
What kind of camera and does it use a capture board?
Did you see any errors or warnings while building ZM?

Hi, cordel,

I googled for this and get some messages. It looks like caused by SELinux. Also, I found one suggest to use 'execstack -c' on the shared object. Then the problem was gone. I don't know the ture reason, but now I could get a still image after click the zone. I'll try to test this part later, maybe after couple days.

Another problem, about the ZM_MPEG_LIVE_FORMAT value under options>Tools is comming. The asf looks not work under Linux mozilla. The help said: "The default of 'asf' works well under Windows with Windows Media Player but I'm currently not sure what, if anything, works on a Linux platform. If you find out please let me know!" Do you have any idea?

SELinux errors usualy show up in the /var/log/messages and look something like :
date, time AVC <error generated>

And SELinux will break so to speak ZM.
SELinux is one of those things that keep getting pushed to the back burner.
Hopefully I'll get around to creating something for ZM soon.
