Hello, all! This is my first post. Thank you for offering this community as a resource.
I'm developing some interactive communications that involve a Blackberry-formatted intranet website.
To this website, I'd like to add some audio and video.
My first attempt was to post an mp3 file to the server and access it via HTTP. I recieved the "413 Request entity too large" message.
So I then looked to how YouTube works - RTSP!
I installed the open source (and VERY easy to install!) Apple Darwin Streaming Server on my intranet server to test and verified that it works by streaming a QuickTime file to my PC.
From my Blackberry, I can use the Browser to successfully access web content from the server. However, if I link from that web cotnent to RTSP streaming content on the same server, I see the error message "Contnet not available. Server is blocked or unresponsive."
Of course, I know that the server is both available (because I can reach it via the Browser) and responsive (because I can stream to my PC).
My theory is that while the Browser looks at my intranet in addition to the Internet, the media player application is only looking at the Internet for some reason.
What are your experiences with streaming to Blackberry from within the firewall? How have you overcome this and/or other issues?

It sounds like you're on the right train of thought.
As it stands currently, RTSP streaming on the BlackBerry can only be done using WAP or Wi-Fi. Since the web server is internal, you can browse to it without issue using the MDS-CS, however, when you go to actually stream content, the browser switches over to WAP which doesn't have access to your internal web server, hence the error.
You MIGHT be able to stream over Wi-Fi. For the moment, I think that's going to be your only way around it.

RTSP works through WAP, which means it's not going to pass through the BlackBerry network. Since it doesn't pass through the BlackBerry network, there's no way for it to get to the BES.
Also, don't forget that everything between the device and the BES is compressed and encrypted, decompressing and decrypting streaming video data on the device side would be an impressive feat. Maybe we'll get there someday.
Right now, I'm not aware of any way to get it through the BES.

So if the initial communication starts over MDS, but flips to WAP to tranfers the RTSP data, then it will always fail. (If the server you are communicating is behind the firewall.)
is there a way to forward the communication through your firewall to support packet trasfer of the RTSP Data, but the initial connection starts through MDS?

I have a similar issue related to RTSP streaming. I am having problem in streaming over RTSP if the Server is behind a firewall. Otherwise, it works just fine.
Ca anyone please explain to me what exactly is happening and whal should/can be done in this case ?
