Re: [Yade-users] [Question #294631]: The tutorial Script 2.6.5 3d postprocessing is giving error
Question #294631 on Yade changed: https://answers.launchpad.net/yade/+question/294631 Marcus Moravia posted a new comment: Hi Jan, You hit the bullseye! The mencoder program was not installed on my system. This solved my problem. I will just open a new topic about how to put together on a 'mpeg' file resulting pictures of 3D view and plot.plots as that performed by Václav Šmilauer in 'Periodic Triaxial Test With Clumps', it would be great if you could help again. Thanks a lot!

Jan Stránský proposed the following answer:
Hi Marcus,
as the error says, there is a problem with mencoder, an external linux
program. What happens if you type 'mencoder' into your terminal?
A workaround is to use snapshot engine and then create movie from resulting
pictures (so exactly what makeVideo does internally). I am sure you can
find some easy-to-use GUI picture2movie maker..
cheers

Hello, I was learning how to record a ' mpeg' file trying the tutorial's

It seems that makeVideo is not working. Can someone please help? I'm using Yade
