Re: [GnomeMeeting-list] Gnomemeeting to netmeeting choppy audio/video.

[jo de baer <jdebaer novell com>]

Bonjour,

in the available codecs section, are checked :
iLBC-13k3, MS-GSM, SpeexNarrow-15k, iLBC-15k2, GSM-06.10, SpeexNarrow-8k, 
G.726-32k, G.711-uLaw-64k and G.711-ALaw-64k.

All the other are not checked. But how do you know which one is used? "-d 4" ? 
The jitter buffer is between 20 and 500ms (default setting).

For video codecs the settings are 8kB/s, and 42 bg transmits. But playing with 
those didn't change it :-).

Indeed ... will check dmeg. Gqcam doesn't have the choppyness, only GM. Can 
you adise other ways of checking what is going on? 

Are the video and audio "related" ? I mean : could the choppyness of the video 
explain the choppyness of the audio I send out?

Thanks so far !!

Jo
