• Use BlockingQueue and add methods to stop send thread. Use a standard Java BlockingQueue (from concurrent package) to maintain a maximum number of outstanding packets for send. Introduce and call methods to gracefully stop send thread.
• Implement finer synchronization granularity for portaudio streams Use dedicated syncronization object in InputStream and MasterStream to implement a synchronization policy with finer granularity. This speeds up processing if SC uses several InputStream, for example several calls that are not on hold.
• Tries to bring back the initial sizing of the CallDialog so that the remote video is displayed 1:1. Attempts to provide smoother resizing of the CallDialog when remote video is displayed inside it.
