I was using openshot and blender to create some animated titles and it was working fine until openshot just started to cry out for blender for no apparent reason. The previews work fine, and some appear to be working. It seems like simple ones involving just text work but any that require 3D modelling do not work. Here's the error I get:
Blender, the free open source 3D content creation suite is required for this action (http://www.blender.org).
Please check the preferences in OpenShot and be sure the Blender executable is correct. This setting should be the path of the 'blender' executable on your computer. Also, please be sure that it is pointing to Blender version 2.62 or greater.
Blender Path: blender
Error Output: No frame was found in the output from Blender
But it was working fine from the same directory before. And it should be a compatible version, as I've got 2.66a installed.
The only thing I can think is that this started happening after Ubuntu (13.04 Raring Ringtail) updated some python files. I'm not sure what they were exactly, but I know there was an update involving Python which I know blender needs to function, so it could be a bug in the latest Python or blender being incompatible with it.
I can also open blender and use it just fine, but I haven't tried rendering anything in it yet because I don't know how to use it, so I'd have nothing to render!
Thanks in advance, let me know if you need any more information and/or logs (but I'm a complete Ubuntu noob, so I'll need some help if you do want any logs :P).
EDIT: Just read Openshot's blog and saw that 1.4.4 was released and available through their PPA. I tried installing that, but the problem hasn't gone away. Here's the PPA if you're interested:
sudo add-apt-repository ppa:openshot.developers/ppa
sudo apt-get update
sudo apt-get install openshot openshot-doc
Another edit: Figuring it was a problem with blender I downloaded the latest version (2.68a) which comes in a .tar.bz2 file which is supposed to be run like a portable application. After redirecting openshot's blender directory to the extracted files the problem still remains. Got it from this site:
