Subject Re: [PROPOSAL] Apache OpenMeetings incubator for Web Conferencing
Date Wed, 28 Oct 2009 14:19:38 GMT
Hello Ian,

Thanks for raising questions. As for OpenLaszlo, I cannot say much.
Some Apache projects use Microsoft compiler, that's legal. I believe
it is quite doable to build OpenLaszlo completely on Apache stack, but
that project has their own authors.

As for Red5, the situation is good and became better. Red5 is no more
than a proxy which re-sends packets from one Adobe player to another.
This is good because we do not dig into Adobe's rtmp packets, and
especially into h.264 codec frames. This saves us from patent
violations. This has some drawback: we cannot mix all video streams
into one - we can just forward them as is. When we get free and
patent-free open souce codecs, we can replace a traffic layer with a
FOSS one.

The better thing is that Adobe finally opened RTMP specification [1].
The specification license prohibits unintended use of rtmp for for
violating digital protection (this somehow relates to new GPL v.3
features) and intercepting video, othewise it is ok.

Disclaimer. IMHO. IANAL.
