Subject RE: GSoC project ideas wanted

Hi Sebastian,

 

My idea for GSOC-2013 is to add recurrence events support for OpenMeetings
calendar.

 

Best regards,

Irina.

Hi Ed,

thanks for your ideas.

About idea no 1:
That is an interesting idea, however it won't be possible that you provide 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:

 - "high" quality will never be better then 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 higher.

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

 - 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 hardly 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 difficult to find
somebody with the needed skills.

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 :

1. The image size of the videos transferred from the om server to the
clients 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  bandwidth 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
window, 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  happy if the subject of bandwidth consumption would plays a role
in the selected GSoC project .

Best regards

Ed
