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.
