Subject: Create source caps information for MPEG-2 streams in TIVidenc1.

If you don't generate this caps information, you will also get errors while
encoding that look like this:

(gst-launch-0.10:1580): GStreamer-CRITICAL **: gst_caps_unref: assertion `caps != NULL' failed

The fact that source caps information was never generated for MPEG-2 looks like
an oversight -- the static caps for TIVidenc1 already allowed MPEG-2.
