rtspsrc: reduce default latency from 2.0 secs to 0.5 secs

By default rtspsrc uses a fairly high default latency of 2 seconds.

I wonder if this really makes sense, and what this is based on.

If there's no Good Reason(tm) then perhaps we should reduce that drastically to something lower, maybe 500ms or even 250ms ?

People who are on very bad networks can still set this to something higher manually.
