This is merely a historical archive of years 2008-2021, before the migration to mailman3.

Jacob Erlbeck jerlbeck at sysmocom.deCurrently micro-secs and RTP rate get mixed when the transit value is
computed in mgcp_patch_and_count().
This patch changes get_current_ts() to accept the desired rate as
argument and to use it for the time conversion instead of always
converting to microseconds. If microseconds are needed,
get_current_ts(1000) can be used.
The arrival_time is now measured in 1/rtp_end->rate seconds so that
it can be directly compared to RTP timestamps as required by RFC3550
(section 6.4.1, see definition of 'interarrival jitter').
