Updates FMJ to r13 (fixes jitter buffer delay computations for some codecs). Fixes an exception in MediaStreamStatsImpl (introduced in r10183).

Updates FMJ to r11. This revision uses an adaptive jitter buffer (for audio streams), which changes size according to the number of packets arriving too late. Passes the net.java.sip.communicator.impl.neomedia.adaptive_jitter_buffer.* properties to the FMJ Registry. Changes the mechanism through which the number of discarded packets is obtained in MediaStreamStatsImpl, now using a FMJ controls. Shows more information about discarded packets and the adaptive jitter buffer in the "call info" window.

Allows the telephony conferences utilizing the Jitsi VideoBridge server-side technology to associate an RTP stream with the participant who is contributing it. Fixes multiple NullPointerExceptions in MediaStreamStatsImpl and OneToOneCallPeerPanel. Fixes an ArrayIndexOutOfBoundsException in AccountID.

Refactors the way specific Codec instances are accessed in MediaStreamImpl. Passes "format parameters" received via SDP/Jingle to codecs, which can handle them (Opus).

Corrects media stream stats documentation and a null pointer exception which occurs when the media stream is closed.

Adds the number of packets discarded by the FMJ packet queue to the "call info" window and to the logs at the end of a call.

Implements a mechanism that allows JMF Controls registered in the  codec implementations to be accessed in MediaStream. Adds a FECDecoderControl interface and uses it to collect FEC statistics in MediaStreamStatsImpl. Adds a "Packets decoded with FEC" line in the call info window.

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.
