I am trying to do a video call between SIP Communicator (Windows) and
Empathy (Linux). Is there a limited set of codecs that SIP
Communicator supports for XMPP? Does it rely on codecs that are
bundled with itself or can it use any codec installed in the OS? I'm
curious about support for Theora and/or VP8. I noticed the codec list
in the video tab of the settings window but I didn't see any other
related information on the wiki about video codec support for XMPP.
Thanks in advance.
