[h323plus] MyPhone 0.4 Released

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.
