ZoneMinder Forums

It could be just me but I'm finding the current SVN version of Zoneminder and Ffmpeg unable to generate videos. I just get the failed to generate video display. I log is created for the event but I'm not sure what to make of it.

Nevermind, looks like it's just something with 9.04. I went back and upgrade 8.04 with the same ffmpeg and today's SVN Zoneminder. Works perfect, even in IE7 when clicking generate video.

Well I'm running ZM on ubuntu 9.04 with the same issue, I'm wondering to know if anybody has the same problem and has it already resolved, or any idea about that. Anyways I wasn't looking has far has I can, so I'll keep it update if I found the solution.

I'm still having that problem on Ubuntu 9.04. Every so often I pull a new ffmpeg from SVN and it still fails to build videos.

I'm thinking of upgrading to Ubuntu 9.10 to see if that fixes it.

I have upgrade to 9.10 and I can not get anything to work now. Did you upgrade and have you got it up and running alright?

I have same problem on Ubuntu server 9.04 and 9.10. It realy works on 8.04?

I'm having the same issue, and it appears the problem in my case is that there were multiple versions of libavcodec on the machine. I've yet to resolve it, due to running out of time, but that seems to be the core of the problem. Do a locate or find for libavcodec If you find it in a variety of locations (/usr/lib, /usr/local/lib, various others) it may well be your problem.

Eliminating the extras seems to be the solution, though depending on which packages installed the libraries in the first place, this is apparently a bit of a pain.

Been battling the "avcodec_decode_video2" error for a little while and the above seems to have addressed my problems.

apt-get remove libavcodec-dev - had a redundant install of the dev libraries
