I have added a item to H323Capability in the CVS called SetMPIValue which should allow you to do what you want.
To work you need to find the capability in the capability list using FindCapability() then you can set the qcifMPI value.

Ok, but what if I want to set, for example, qcifMPI to another value?? Is it possible?
BTW, have you got any idea of what it is going wrong with the video bandwidth management? As I said before, I can send you Wireshark traces, if you need them.
Best regards,

To set the qcifMPI or cifMPI simply set the frame size to QCIF or CIF in the myphone2 settings.
The *-QCIF codec has the qcifMPI set to 1 and the *-CIF codec has the cifMPI set to 1.

Hi again,
After more testing, and a search through the source code, I've seen that the AdaptivePacketDelay code is supposed to be included in the new plugin, so forget my previous post. Just another question: How can I set the qcifMPI, or cifMPI parameters??
Thank you in advance,

If memory serves me right the openH323 version never handled I-Frames. I will relook at the plugin codec to see what we could of missed.

Simon,
Unfortunately, even when the plugin codec code is called, MyPhone2 stills sending more video bandwidth than established. If I don´t move the camera, it sends about 50 kbps (the configured video bandwidth), but if I move the camera, to force sending I-Frames, the bandwidth increases until reaches more than twice the configured bandwidth. The same test works fine with the previous version of openh323 and MyPhone. What's happening? If you need them, I can send you Ethereal traces.
Best regards,

Ya'oops when a decendent is not a descendent. :( I have checked in a fix to h323plus CVS so the correct H323PluginVideoCodec::SetMaxBitRate() is called.
Thanks again

Hi,
Simon, I've traced down using the VS 2003 debugger, and the function which is being called is H323VideoCodec::SetmaxBitRate(), because the function OpenVideoChannel() receives a reference to H323VideoCodec, not to H323PluginVideoCodec. You can see this easily setting a breakpoint in this line codec.SetMaxBitRate(videoBitRate * 1024);, stepping into it and seeing the call stack. Here it is:

H323PluginVideoCodec::SetMaxBitRate() sends a messages "Max Bit Rate" to the
plugin codec to set the maximum bitrate. This function also overrides
H323VideoCodec::SetMaxBitRate() since H323PluginVideoCodec is a descendent
of H323VideoCodec so the problem most likely is in the plugin codec not
setting the max bit rate. I suggest you look at the H.263 plugin codec
perhaps there is something missing.
