Hi Ed,

thanks for your ideas.

About idea no 1:
That is an interesting idea, however it won't be possible that you prov= ide a "free to choose" bandwidth for each user.
The background is: Every stream that any client consumes has to be created somewhere.
So what could be realized is that every stream that is broadcasted from one user via webcam to Red5/OpenMeetings will be re-transcoded into multiple streams (high, middle, low) bandwidth.

So there might be some limitations to that:

=A0- "high" quality will never be better t= hen the original material. We can't make a picture better then the original= . So all re-transcoding will only make the original to lower quality, never to highe= r.

=A0- Re-transcoding has to happen on the server side= (and number of streams are limited, we can't provide a stream on the require= d bandwidth "on-demand" for each user, or only with very big effort= )

=A0- it will require real-time transcoding on server= side which is possible with FFMPEG and some integration into Red5. But we would = need a very specialized student that is keen and very motiviated as there is har= dly any documentation on that available in the internet.

What a project makes a success is if all participant= know the potential outcome and the tools and methods that are needed to realize that. I would be happy to put this project on our list but it will be diffi= cult to find somebody with the needed skills.

Sebastian

Hi all,

I think, one of the gratest liminations for satisfactory video conferencing with om is the limited bandwidth of internet connections of the clients . Therefore I would like to suggest the following ideas for a GSoC project :<= br>
1. The image size of the videos transferred from the om server to the clien= ts should be adapted to the video window size set in the recipient client.
Thus the recipient client itself could influence the transferred amount of = data to it.
Then all the participants achieve the best possible result for them.

2. A second proposal concerns that the screensharing =A0bandwidth requirements has an great impact on the overall quality of the video conference.
Here, in a project the existing function of sreen sharing could be expanded= and enhanced.
For example, the possibility for the transfer on only one application windo= w, regardless of its size.
Or the possibility of shared browsing with a locally installed browser.
Moreover, certainly an improvement of the used compression method would be = a very good project topic.

I would be =A0happy if the subject of bandwidth consumption would plays a role in the selected GSoC project .

Best regards

Ed
