I assume you mean you wish to change the caps from within your src
element. If you're using 0.10 I believe you can just change the caps
you set on the GstBuffer, which will start renegotiation. In 1.0 I
just send a STREAM_START, CAPS, then NEW_SEGMENT event before sending
the next buffer, but you might be able to get away with just sending
the CAPS event.
