Work is pending on video codec plugins. Hopefully we will be able to
make an announcment soon.

As for using gstreamer, there are two problems:

  - Gstreamer is LGPL. This would have to be resolved with the MPL used
by the OpenH323 and PWLIB libraries that will implement the plugins

  - Implementing the codecs is only half the problem. Implementing the
RTP transport and capability definitions for each codec is non trivial.
