Hi,

I searched the net and tried like 1000 things to get ffmpeg working to generate mpg from my img files and it isn't working.

When trying to generate a movei from an event it gives me:

" Video Generation Failed!"

In /tmp/zmvideo.log i see:

01/28/09 22:39:32.266184 zmvideo[7109].INF [Creating video file Event-16122-r1-s1.mpg for event 16122]
01/28/09 22:39:32.268280 zmvideo[7109].ERR [Unable to generate video, check /home/zm/public_html/events/1/16122/ffmpeg.log for details]

but when looking for ffmpeg.log it doesn't seem to be created anywhere

Any ideas?

I had ffmpeg working on older ubuntu version

without changing a thing

See my wiki entry Fixing Bug to Export Videos and see if it helps.

I would also like to get video generation to work, and did try what is mentioned in the wiki. While I do not want to hijack this post, I think that my questions are on the same topic as the original post so I am including it here.

I get a "sh: ffmpeg.log: Permission denied" in the error_log, and can find the ffmpeg.log file in the events directory but get a "no such file or directory" error when trying to "sudo more" the file even though the file shows up as a 54 byte file with "ls".

Actually changing that line I foud in the wiki solved my problem ... just need to find out how to set quality higher
