[Asterisk-Dev] video in iax2 spec

Hi,

> it's almost impossibly difficult to actually use in an application
Wow.
   That means that all the applications I have written (which use 
   openh323) are examples of  near impossible feats accomplished. 

you are right - openh323 is hard to use, if you do not understand 
threading, or C++.

> The fact that Gnomemeeting works with OpenH323 proves nothing
Rubbish.
  GnomeMeeting, for it to run on any box requires the presence of 
  the libraries pwlib, openh323, and the openh323 executable.
  GnomeMeeting does not require the source of the libraries to run.

 Did you hear that Gnomemeeting has been considered for placing on the 
default desktop? Does that suggest Gnomemeeting is highly stable?
  yes - gnomemeeting is stable. If only all apps were as stable

Or, does that mean the chan 323 developers did not understand threading
etc, or did not understand the programming model of openh323? My inbox has
had multiple emails from Michael (developer of chan_oh323) and I have
explained to him where he has altered openh323 variables in a non thread
safe fashion. If you do adjust openh323 variables in a non thread safe
fashion, you are going to get random failures that are hard to debug.
For the record, chan_oh323 is (in my view) the best opensource h323 
channel for *

I don't understand your gripe - the chan_h323 etc require the source cause
they require a particular library version/api. 
chan_h323 requires you to have built the required library versions (to 
get the right library), which means that you do need the library source.
Is that openh323 fault, or the chan_h323 developer? If you could use the 
latest library, the openh323 include files + and .so files is all that is 
required.

Derek.
