* Add code to pace sending a stream when it is being sent from a file.
We limit the datarate to twice the average datarate (however the first
few seconds are sent flat out to help with prebuffering).
* Add the initialization of the rc_eq fields and the like for VIDEO codecs.
* Add the missing get_arg calls for VideoQxxxx
