Determines maximum possible encoding time for frame that will
allow it to encode and arrive in time (as determined by QoS events).
In particular, a negative result means encoding in time is no longer possible
and should therefore occur as soon/skippy as possible.
If no QoS events have been received from downstream, or if
#GstVideoEncoder:qos is disabled this function returns #G_MAXINT64.
