Fix bug in VPx codec configuration. 

Before, we converted the WebM configuration to MP4 in the video
client, however this lead to a bug when fields were missing.  So
now don't convert until the cluster parser so the extra info from
the stream can be added.

This also fixes a bug where the value was not printed in the warning
logs.
