videomixer) fail to negotiate.

timeoverlay ! _mixer.

basetextoverlay: schedule reconfigure on source pad when negotiation fails
The source pad might be flushing while negotiating, resulting in
set_caps or the ALLOCATION query failing. In this case set the
reconfigure flag on the source pad so that negotiation is retried on the
next buffer.
