P2P Audio / Video streaming
Hi Friends,
We are planning to build a P2P audio / video, client / server application.
The question is:
Here, since we are not sending data in blocks using session.write(), we need
to stream the audio / video data as they arrive from the microphones. Taking
the same chat example, would it be possible for us to build a P2P audio /
video streaming client / server? What do you advise?
Pat

Thanks Norman for your reply.
Interesting!!
Since we are trying to build both client and server which work on a P2P
model, I was wondering if anyone had tried building something similar in the
past.
We have to simulate streaming the same on both the P2P server and the client
as well using Mina. Server will have to reforward the incoming stream from
the client to other clients in the session.
Some sample code would help.

Hi,
maybe its a bit diffrent but I wrote a TCPSoundStreamer with MINA. I use
"BARIX" Hardware on the other side which handle raw TCP Streams and
stream the mp3 via MINA as client. I use the StreanerWriteFilter to
stream the mp3 ( which is stored in mysql).
If you have concrete questions just ask ;-)
bye

I think streaming the data over UDP is the solution. I am not too sure how to
do it with Mina though! Block wise of shooting data will probably
deteriorate the performance down and may not be the optimal way to do it.
I think Java provides a interesting way to do the audio / video streaming.
Since Mina offers a nice platform to program, we have considered it.

Don't you still need to write it in some form of blocks, though? What would
you do with raw UDP sockets that would be any different?

Hi,
If you write/read sound samples from a sound board, it will be in form
of a buffer of fixed length with "interlaced" channels
(mono,stereo,5.1,etc..) . So you can put those buffer in UDP packets,
it'll basically works if you are on a reliable (and fast) network. For
more advanced streaming you could take a look at protocols like RTP for
help you to deliver samples over UDP in orders.
Julien
P.S. : My main business is to write audio streaming devices/software, I
got a small device streaming voice over IP, with multicast capabilities
ready if you want :)
