_Me_ a global understanding!? Well, I have already hacked a little the
sound support, I just took a deep look at the video support, but for
openh323... Let's say that I don't either understand, nor have a global
look at the thing. Damien will come back next week and enlighten us! ;-)

Hmmm... I grepped through openh323's sources, because I must admit the
thought of using a plugin system for device support crossed my mind (in
fact, the long mail you answer to, is basically what I thought would be
a first step towards this end: put complex things where they belong, and
not in the client program; the second step being the plugin system). It
seemed openh323 was indeed quite cleanly done: it doesn't play tricks
with driver support. But it still uses pwlib...

Ah, gstreamer... Ah, modular things...
