OS: Ubuntu 5.10 with ZM adapted from the Debian 'HowTo'

I'm getting an error in zmvideo.log

Creating video file Event-565.mpg for event 565
/usr/bin/ffmpeg -y -hq -intra -r 5.59 -s 320x240 -i %03d-capture.jpg Event-565.mpg > mpeg.log

It seems like the get_buffer() function has failed.

Any ideas as to why?

I think you need to set an output frame rate of say 25 fps for this codec.

The only way I could get this to work was by hard coding '-r 25' into /usr/bin/zmvideo.pl Nothing else seemed to work. I also removed the default setting in OPTIONS.

Anyway, sorted now, thanks for the pointer.

Depending on what version of ZM you have there should be an option, ZM_FFMPEG_OUTPUT_OPTIONS, where you can put this.
