[h323plus] Call Rate Issue using H323plus

The codec definition (in the plugin) sets the upper BitRate limit for the
codec. if you set a targetbitrate higher that the maxbitRate from the plugin
codec then it is ignored.
For instance H.263 CIF will not exceed the 384k set in the codec definition.
To fix just change the maxbitrate value in the plugin codec.

Hi Simon and h323plus members,
I manage to get it work in the situation where SetInitialBandwidth is set to
video type and less than 384kbits.
The other terminal will be notified and sending video below the limit.
But it fail when I set more than 384kbits, for example 512kbits or 1Mbits.
Is there a default value that defines the limit?

There has been some improvement in bandwidth management in the current CVS.
There are 2 parts 1 what we limit what we send and what we request the
remote to limit to.
When setting the local bandwidth this can be set by your derived
H323Connection::OpenVideoChannel function ie codec->SetMaxBitRate() .
To set the remote there is an improved function
H323Connection::SetInitialBandwidth(H323Capability::MainTypes & captype, int
Which you can call when you instance the connection object which will limit
the bandwidth of all advertised capabilities in the TCS to the value you
specify and that should limit the bandwidth the remote requests in the OLC
and hence what it will send.

Does anyone know how to set the call rate for a conference?
In my H.323 application that use h323plus library, it use
384 kbits by default to create a conference.
I have try to use function SetInitialBandwidth(51200)for 512kbits call rate,
but it also fails.
