The problem is that the device only seems to support raw udp and rtp. So
I don't seem to have the choice here :-(
Can you elloborate how the ordering scheme be implementated ? Whould it
be a IoFilter ?
Thx for your time.

I expect the sound is out of order because you are using UDP which
does not enforce packet ordering like TCP. The fix is to either use
TCP or create your own ordering scheme. If you do that, you will also
need to handle dropped packets as UDP doesn't guarantee delivery
either. If you add too much overhead to UDP, you can easily make it
perform worse then TCP, so that's something you need to test. Good luck!

Subject: Writing a Server to stream mp3 via UDP
Hi all,
we bought some device which recieve mp3 streams via udp (raw) as a
prototype. Now we want to build an app which streams some raw udp
data to this device.
I wrote some quick code with mina. The good news is that it play some
sound, the bad is that the sound seems to stuck and is not in the
right order.
I tried to use StreamWriteFilter to write directly the given
InputStream. I think I need to suspend the write when the buffer of
the device is full. But how can i detect this ?
Any idea ?
The second problem which is that I have no idea howto calculate the
paket sizes which i need to use for the various mp3 bitrates.
Any help is welcome :-)
bye
Norman
