    Problems with wireless network when play live streaming : RTSP

    Hi !
    Somebody can help me fix my problems. I building an app Java on Series S40 Touch & Type to play video live streaming RTSP.
    - I don't know why my app can play with some wireless network but it can't play with another wireless network which have the same quality. May I have to configure something for my network to play video live streaming RSTP ?
    - Besides, If I use 3G I can't play my app on Asha 303 ( S40 Touch & Type ) Error : not enough bandwidth. quality is less than normal, but I can't play it on Nokia E71(S60) and Nokia 500 (Symbian Anna). What's the different in supporting 3G between Asha 303 and Nokia E71,Nokia 500 ?
    Thanks for your help !

    Could it be network operator specific limitation?

    Do you mean that your application is not working (cannot stream video) on any of those devices when used on a 3G network?

    About streaming with Java ME on Nokia devices, have you checked these on Java Developer's Library?:

    Java Developer's Library 3.13 > Implementation notes > (JSR-135) Mobile Media API > Series 40 class and interface description > Streaming

    Java Developer's Library 3.13 > Implementation notes > (JSR-135) Mobile Media API > Symbian class and interface description > Player > Streaming

    Re: Problems with wireless network when play live streaming : RTSP

    Thanks r2j7 !
    - I have a big mistake. I can't play on Asha 303 but i can play on some other devices like E71 or Nokia 500...I want to ask about the different in supporting 3G with these devices...
    (In fact, the quality of 3G in my country is not really good)

    - when I test with some wireless network same quality, some I can play my app but another I can't play. So I wonder that whether I have to configure something with my network devices to play live streaming Rtsp ?

    Re: Problems with wireless network when play live streaming : RTSP

    Hi,

    I've faced the same problem with you, achilles205. I cannot play rtsp url in wi-fi connection. But when i choose 3.5G Network, it says "not enough bandwidth. quality is less than normal". Could you share how you solve this issue. Your last question was how to configure the network in devices to play rtsp?
    Anyway i'm using Asha 311 as testing device.

    You may need to enable RTSP protocol on your network/wifi router and allow the RTSP ports:
    TCP: Typically, RTSP uses TCP as its transport protocol. The well known TCP port for RTSP traffic is 554.
    UDP: RTSP can also use UDP as its transport protocol (is this ever done?). The well known UDP port for RTSP traffic is 554.

    Check with your Network engineers for allowing traffic on TCP/UDP port# 554.... then it should work.
    thanks,

    Re: Problems to play live streaming : RTSP

    Some operator configurations (pre-installed by Nokia at factory) do not include RTSP settings („account“). On WLAN enabled Series 40 phones, all configurations which include RTSP and I saw so far are wrong. Your user has to fix his manually: Menu » Settings » Configuration » Personal settings » New or Options » Add new » Streaming » do not edit anything and hit back » highlight that new setting by long tapping it » Activate. Now it works via Wi-Fi and GSM and UMTS. However, it won’t get better than that.

    You cannot do that from a Java MIDlet. You could send a configuration by SMS, however, you would have to send one configuration for each operator. Rather than that, try to educate your user(s).

    If your network operator has a specialised APN for streaming, you have a even bigger problem: Such a new setting conflicts with GSM/UMTS because you have to use the „preferred access point“ to get RTSP working with WLAN. If your network operator has a specialised APN for streaming, your user has to switch the preferred access point manually, when using GSM/UMTS again. However, very few mobile operators use such a specialised RTSP access point.

    Question Re: Problems to play live streaming : RTSP

    Hi,

    Currently I developed for Nokia Asha 311.
    If I just open the rtsp address via browser the native video player will
    pop up and streams the video with the audio, and with this code the
    Video streams smoothly but no sound at all.

    Can anyone pls help me in that?

    Thanks in advance.

    Re: Problems with wireless network when play live streaming : RTSP

    hi,

    We have got a problem with Nokia Asha , whenever we try to play the RTSP link with :554 the links wont play and if I delete the :554 the links starts streaming

    for example

    rtsp://<ip address>:554/2G/LIVE/videoF.sdp ( wont play )

    and

    rtsp://<ip address>/2G/LIVE/video.sdp ( plays )

    please suggest.

    (Remark: the :554 problem is discussed in an other thread, http://www.developer.nokia.com/Commu...links-with-554, but it is good to keep the description here)
