[Live-devel] Multiple unicasts clients for one Framed Source

[Rawling, Stuart]

Thanks Ross,

After following your advice, I went back to basics, and have discovered that
if I did not set the (mpeg4) config attribute in the sdp, the effect was
that my on demand server went a little funky if more than 1 client
connected.  The setting of the config flag was next on my to do list.  But
because of this find has jumped to the forefront.

I am limiting the amount of code I am writing to extend the library to my
needs, and only doing so through subclassing.  I just missed the need for
the SDP to be generated from my mpeg4 source, luckily there is the
getAuxSDPLine function I can overload to accommodate this.
