RE: [Linphone-developers] Error in msx264 plugin?

[Sven Westergren]

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
