..Has anyone checked if it works on a direct connection? Through a vpn- account, for example?

I installed Realplayer to use rtsp on my laptop. I browsed through m.youtube.com and everything worked perfectly.

I can watch rtsp over my laptop but I can't with my P1i.

@OffLineR:
Right. ..Might actually be that the p1's media player (and/or connection handler) won't try to establish new connections out when it starts to lose them. Which probably will work well on a wap- gateway, since it will renew the connections for the phone, and probably not need to negotiate the connections to keep them open. Which an ordinary router will have to, or it will just discard them after a while.

Which (if the shamanic debugging skills didn't fail me) explains why I managed to get streaming to work pretty good now after 1. setting my speedtouch- router on low firewall- settings (to allow all traffic out, which might allow the phone to keep it's connections), and 2. increased the timeout for tcp- connections (probably will have to do this via the cli- interface on most routers). (Tested this on a clip on m.youtube that only ran to 2min, but ran to the end of 8min (or so) after the tweaks.)

I'd really like to know why they've chosen this setup for the phone, though.. I guess it could have something to do with the security model - that the phone shouldn't be able to connect out on it's own. Perhaps it's got something to do with the way it idles connections? Maybe it won't use status packages in the usual way..?

I suppose it does save a lot of traffic, and problems, on the occasions where you don't want connections to open until it fills the stack, though..

I think the tcp stack is optimised for direct gprs/3g connections. Much slower connections than wlan that aren't firewalled and are designed with completely different latencies etc etc etc

Also remember that installing realplayer on a desktop is not the same as running the media player on the p1. The media player on the p1 will be - at best - a distant relation of the modern realplayer, which will be much better at dealing with the ummmm nuances of wlan. The third issue is what ever the network providers actually do to the internet connection you are using, could this be a qos issue? missing packets, excessive retries, long gaps and not enough buffering on the p1? proxies? who knows

Mm. Sceptical. I think there's just no altitude for "error" on the abstract connection level at all..

(...allright, that's it. I'm going to flash the phone, wish me luck. )

Good luck you won't need it, i'm sure

There. And I still have nails left.

Apart from the new wlan- icon.. the phone opens more connections without slowing the phone down, now. So whatever they did, it's.. at least better than before. Seems to me it won't just time out the active connections, either, so this is.. probably very good news? (I seriously wish SE could come up with some official changelog, though..)

I'm not educated enough to get into technical stuff regarding WLAN, RTSP and RTP protocols, etc. I know enough to enable/disable the features on the router/modem, or forward required ports, etc. Sorry... didn't study networking.

The issue I'm facing with the media player is this: It accesses the content and starts buffering. After that (it says) it reaches a 100% and stops. Doesn't play the clip. What gives? That leads me to believe that its something inside my version of the media player software and not necessarily a WiFi/protocol issue. (Referring to what pnf1973 mentioned regarding firewalls, my friend's Palm Treo 700p played the same content over the same network and worked. What did it do differently? Has to be something within the device and not the network. That tells me that my network settings are configured correctly.) Maybe a missing codec? Cos I've observed this behaviour on computers as well, where it will begin to stream the clip into memory and then realize that you don't have the required codec installed. Maybe if there's some way to look at the codes in the media player software from someone who has it working and someone who doesn't, maybe a bug can be found.

I wish.. At least we can test it, and see if we get the same problem. ..What sort of file were you trying to stream?

..btw. I'm pretty sure the next to last firmware has some sort of serious problem with trying to renegotiate the open connections. So it's possible you'd run into problems like this on a network with.. er.. that you will have all these problems on any actual network (that isn't a virtual one, probably). But if you get this all the time, I think SE support would probably be happy to get an e-mail about it (with the links to the file and so on).

..Could you test the same file on a wap- connection?
