osmo_ortp.c: Duration of a RTP frame affects timestamp of the next one

Duration of an RTP frames dictates the timestamp used for the next
frame, not for the one being sent now. It was done like this before to
account for possible losses.
Implementation wise, the duration was understood as "duration
between last frame was sent and now when current one is sent". It makes
more sense to use it as the duration in number of sampling ticks
as described on the function documentation, specially now that we can
account for extra time by means of osmo_rtp_skipped_frame.

libosmo-abis - Osmocom Abis interface library

This repository contains a set of C-language libraries that form the A-bis interface library of Osmocom Open Source Mobile Communications projects such as OpenBSC / OsmoBSC.

Historically, a lot of this code was developed as part of the OpenBSC project, but which are of a more generic nature and thus useful to (at least) other programs that we develop in the sphere of Free Software / Open Source mobile communications.

The libosmo-abis.git repository build multiple libraries:

  • libosmoabis contains some abstraction layer over E1/T1 and IP based ETSI/3GPP A-bis interface. It can use mISDN and DAHDI as underlying driver/hardware.
  • libosmotrau contains routines related to A-bis TRAU frame handling

Homepage

The official homepage of the project is https://osmocom.org/projects/libosmo-abis

GIT Repository

You can clone from the official libosmo-abis.git repository using

git clone git://git.osmocom.org/libosmo-abis.git

There is a cgit interface at http://git.osmocom.org/libosmo-abis/

Documentation

There is no Doxygen-generated API documentation yet for this library. It would be great to some day have it, comparable to libosmocore.
