Hello,

 

We have a problem with webcam resolution in MCU 4210 conference with RPD 3.8 endpoint. It is very low:

 

Output: SIF, H.263+, 1.86M, G.711U
Input: 320 x 180, H.264, 1.86M, G.711U

 

Integrated camera in Asus ET2701 A-i-O with Windows 7 installed is certainly able to handle HD.

Here is diagnostic info for test MCU conference with one participant :

Rx and Tx bandwidth on MCU is configured as 2 mbps.

 

Is it possible to raise quality on the end points. I\m pretty sure that MCU is able to handle resolutions up to 704x576.

 

Regards, Andrey.

One more question, why local self-view image is mirrored? But everything is ok in conference view.
