 Betreff: Re: Screen Sharing too slow

 screen video is encoded using screenv1 codec
 h264 is more CPU consuming, h263 is currently used by default for video

 medium quality do reduces video picture size, you can zoom it back
 while viewing

 Thanks FJ,
  That means that it is a bandwidth issue?. The problem with Medium
 quality is that the screen is smaller. Is it possible to reduce the screen
 quality without reduce the screen size?, like reducing the definition.

  Thanks.

 Hi Maxim/all,

 I have OM 3.0.4 (stable) installed in a VM with Debian 7 with 2.5 GB
 Ram, 2 CPUs. I have tested the Screen Share function with 2 users conected
 to OM, both are conected via Wi-Fi (band N). The problem is that with the
 configuration of High Resolution and 10 FPS the screen share is very slow,
 it has a lot of delay. Sometimes the screen freezes and then continue. The
 video (small size) of the person that is sharing the screen, gets very slow
 too. I did the same test with your Demo server and I had the same problem,
 less slow but slow too. What do you think the problem is?When I shared the
 screen using my VM as OM server, CPU was at 30% and Ram at 20 %.

  Thanks in advance.
