High Network Trafic from client to Red5 when streaming screen

Good day to All,

I am testing screen streaming and recording using a customized code based
on OpenMeetings.

I have noticed high Network traffic going to Red5 server when the screen is
viewing a movie and have the following questions:

Is it possible to replace ScreenV1 codec for screen streaming and recording?

How can it be replaced? With what codec? Please let me know if there are
any open source examples.


If the codec cannot be replaced, what could be the appropriate way for the
program to detect heavy data being transmitted and reject it.


 Thanks,

Sonia

Hello Sonia,

this email is more about OM development :)))
let it be in this list

According codec replacement: there is JIRA
https://issues.apache.org/jira/browse/OPENMEETINGS-112
It was created back in 2012 ....
I have performed search for codec (Apache License compatible) but with
no luck :(

I see several possible way of improving screen capturing:
1) detect if ffmpeg is installed on client machine and use it for
screen capturing
2) use WebRTC screen sharing (5.0.0)

Hopefully I have answered your questions
