Hi Simon,

No, the Codian is not able to decode the video (though all other clients we 
have tried can do it).
Linphone is running on Windows 7 (our project uses mediastreamer2 and oRTP only 
but we tested this with Linphone to remove unnecessary error sources)

Best regards
Sven Westergren

Is the codian VCS is able to decode the video or not ?
Using linux or windows ?
