[android-developers] Re: Multicast Receive
Thnx for the reply. But , I dont think that it is a problem of the device as I am able to play the same RTSP stream using VLC player and Media player on the same device. This is my effort to play the RTSP stream manually by handshaking first , then receiving the video UDP packets. I am really directionless on how should I go about getting the multicast data. - Jasleen On Sep 24, 2:41 am, rp.circ rpress...@circadence.com wrote: It seems that receiving multi-cast may be a problem forsome devices: http://stackoverflow.com/questions/3623143/multicast-on-android-2-2 And being that you have it working on other platforms...It would be great if you could get shark for root on your phone to actually see if the packets are making it to you.

[android-developers] Re: Multicast receive broken in Android 1.5?
Same issue here too. When I retrieve my kernel config file from my Cupcake-upgraded G1 device (by using adb pull /proc/config.gz .) and when I look for CONFIG_IP_MULTICAST, then I find the following line: # CONFIG_IP_MULTICAST is not set Therefore I guess that multicast is disabled in the kernel. It would be interresting to check with a G1 which has not been upgraded to Cupcake. If CONFIG_IP_MULTICAST=yes is found, it would confirm that the kernel has lost IP Multicast during the Cupcake upgrade.

[android-developers] Re: Multicast receive broken in Android 1.5?
I have the same problem after upgrading to 1.5, and it seems it's because the IP Multicast join packet is never sent out. I reported the bug here: http://code.google.com/p/android/issues/detail?id=2917 On May 31, 11:38 am, Dave d...@devbury.com wrote: I have an application that sends and receives DatagramPackets on a MulticastSocket. This application works fine on Android 1.1. I just loaded the application onto Android 1.5 and it can no longer receive packets from other hosts. It can receive the packets that it sends out though. Packets sent from android 1.5 do make it to other hosts. Did something change in 1.5 or is something broken? I'm using the dev phone 1 and not the emulator.
