Simon, 

Maybe the problem is that the funtionality that was implemented in the old H323_H263Codec::Read() method has gone away, isn't it? It seems that in that code was implemented the adaptivepacketdelay feature. Is right?

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

  Simon

    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.

Simon
