[Linphone-developers] Question about speex

[Sven Westergren]

Hi,

Can someone explain to me the reasoning behind this recalculation of bitrate in 
the speex plugin (msspeex.c)?

  /* convert from network bitrate to codec bitrate:*/
  /* ((nbr/(50*8)) -20-12-8)*50*8*/
  int cbr=(int)( ((((float)s->maxbitrate)/(50.0*8))-20-12-8)*50*8);

I have searched the speex manual but I can't grasp what is going on here.

Best regards
Sven Westergren
