demux/remux pipeline hangs when audio is added

Wed Oct 2 12:37:42 PDT 2013

I do not have the plugin ffmpegcolorspace. I am assuming it is just not
installed because I am missing a library or something. Can you tell me
where it is located in the plugin structure? I am using gstreamer 1.0. I
didn't see it listed on the plugin overview page in the documentation.
