[Galene] ANNOUNCE: Galene 0.4

[Juliusz Chroboczek <jch@irif.fr>]

Dear all,

Version 0.4 of the Galène videoconferencing server is now available:

    git clone -b galene-0.4 https://github.com/jech/galene

For more information about Galène, please see

    https://galene.org


Version 0.4 has seen some major server-side changes.  The main new features
are simulcast and scalable video coding (SVC), which allow different
clients to receive flows with different resolutions and different image
qualities; we currently reduce framerate when a client is congested, and
reduce quality when a client has reduced their window size.  Resolution
can be controlled manually at the receiver through the side menu,
framerate is decided by the server.

The server should now be more robust, the issues with streams being
silently lost when under load should be gone now.

The code that records videos to disk has been mostly rewritten (we now use
our own depacketiser rather than relying on the one in Pion), and has
learned to deal gracefully with packet loss; you should no longer see
corruption in saved videos.  There is now support for saving H.264.

The signalling protocol has seen some improvements, notably the ability to
signal user states ("hands up", mood, etc.).  This is not currently used
by the user interface.
