The same question might have been asked but I didn’t find any solutions available for me.

I’m trying to play RTSP stream in android and the server is Darwin streaming server. For now I’ve tried VideoView and MediaPlayer, both of which always work fine when I use 3G but have problems when I use Wifi sometimes, specifically when I use Wifi at my workplace, and the error in LogCat:

PlayerDriver( 31): buffering (0)

I have googled around and guess the reason maybe the Wifi hotspot is behind the firewall and the UDP port is blocked, and the Opencore media framework only supports RTP over UDP. Correct me if I am wrong.

Then, here is my question, how can I solve it if i cannot change the firewall situation. If using the build-in VideoView/MediaPlayer is not possible, then how to write my own rtsp client.

Any suggestion will be appreciated:)

Thanks in advance!

    I don’t think that you can do much with this… Heres my idea:

    Make an app that will be started in the same LAN as Darvin, then it will get Darvin’s RTP stream which goes over UDP (in LAN) and then transmit that over TCP to WAN, so you can access it. You can easily write that app in C#… and it will work perfectly. Or if you have some Linux distro, you can write a complex Bash script that will use NC to do the same…

    So this is basically the idea:
