- Removes the DirectSound support from PortAudio in order to prevent issues with bad audio quality.
- Attempts to recognize USB PortAudio devices on Windows as such, ignores the virtual Microsoft Sound Mapper devices to avoid user confusion. Contributed by Vincent Lucas.

Adds an Opus configuration form and changes the default Opus settings. Updates the Opus JNI binaries. Notifies encoders that implement PacketLossAwareEncoder (Opus and SILK) of packet loss information received via RTCP.

- Prevents a NullPointerException in ice4j's Connector#stop() which appears quite often with unknown side effects.
- Prevents a NullPointerException in ToolsMenu related to the Jitsi VideoBridge menu item which causes of long chain of other exceptions and, eventually, prevents the application from completing its startup.
- Moves the C source code of JNI PortAudio library from Jitsi/net.java.sip.communicator to libjitsi/org.jitsi. Removes a couple of Java method and C function implementations each of which repeats three times. Fixes possible cases of leaving native callback threads which have been attached to the JVM in undetermined states.

Fixes a discrepancy/inaccuracy in the RTP buffer length and minimum threshold of FMJ which leaves it vularable to even the tinies hiccups of the network. Rebuilds FMJ and libjitsi with debug information such as line numbers.

Updates library jni portaudio for Linux-32. Includes stdin.h and corrects warning about intptr_t in net_java_sip_communicator_impl_neomedia_portaudio_PortAudio.c (as suggested by Lyubomir Marinov).

Updates FMJ to r5 from the sourceforge SVN repository. This version uses a java.util.logging.Logger to log, and logs detailed statistics from the RTPSourceStream class. Changes MediaServiceImpl to always enable FMJ logging.

Improves device selection via portaudio for MacOSX (hostapi coreaudio): adds the possibility to get the device transport type (USB, bluetooth, etc.) and an unique identifier. Corrects problems when: loading the same device twice (for the moment only for the same hostapi), a new plugged device is selected during a call or if the selected device is unchanged.

Replaces the Opus libraries with ones linked against a lower version of glibc (so that they run on debian, for example)

Adds support for the IETF Opus codec (patch by Boris Grozev). Fixes a problem that prevented Jitsi from using formats that are disabled by default (pach by Boris Grozev)

Fixes an issue which would leak at least one Thread per call which would endlessly send out RTCP packets.

Fixes a failure to keep the aspect ratio of the video when switching to full screen. Attempts to remedy a multi-video display when switching between camera and desktop streaming. Tries to fix a crash in the QTKit video capture on Mac OS X. Works on addressing a unnecessary remaining of the camera on Mac OS X open.

Re-applies the ideas of r9718 with a refined implementation on the PulseAudio Renderer in order to reflect changes to the user's choice with respect to the default playback device while in a call.

Fixes UnsatisfiedLinkErrors with detail message 'Invalid access to memory location' in jnawtrenderer.dll and jndirectshow.dll.

On behalf of Vincent Lucas, commits a fix to the calculation of the Last SR (LSR) timestamp for the Sender Report RTCP packet.

Commits an initial version of the libjitsi library which should be fully functional with respect to neomedia/MediaService and should be usable with and without OSGi.
