[GMG-Devel] Python exception uploading video on CentOS 7

[Ian Cross]

Hi,

I have a python exception when uploading video, the stack trace is below. I 
installed the latest stable version (git clone 
git://git.savannah.gnu.org/mediagoblin.git -b stable) on the latest CentOS 7 
today. Images and other functionality seem to work fine. I tried to upload test 
WebM videos but neither of my samples worked:  
http://permadi.com/thirdParty/videos/redcliff450.webm and 
http://video.webmfiles.org/big-buck-bunny_trailer.webm.

The exception occurs on line 96 of media_types/video/processing.py - foreach() 
takes exactly 3 arguments (2 given).

I am wondering if I have not installed gstreamer and python bindings correctly 
or at expected versions? I installed packages gstreamer gstreamer-python 
gstreamer-plugins-good. Any help much appreciated, thanks!

Ian
