This is an issue a user has experienced with Arista Transcoder. Original issue
can be seen here:

    http://github.com/danielgtaylor/arista/issues#issue/12

The issue is with this file:

   
http://ia331209.us.archive.org/0/items/Patent_Absurdity/Patent_Absurdity_LQ_350kbit.ogv

When transcoded to H.264/AAC in MP4, the output container seems to contain
copied values from the input container and this makes other GStreamer-based
applications report the file's video stream as Theora when in reality it is
H.264. FFmpeg and such report the video stream properly as H.264.

The command being run internally is similar to:

    gst-launch-0.10 uridecodebin
