Hello < Olenyov Kirill> it appears to be UDP RTP

Souhail Marghabi · Answer

There is so little Docu about Gstreamer amd what i mostly find on the internet is devs publishing stream from android camera to service My purpose here is the opposite Server sends h246 stream and the app should display it live in a Surfaceview like container

Olenyov Kirill · Answer

What is 192 168 1 103 Is it android device or video streamer How the streamer is configured Where does it stream

Olenyov Kirill · Answer

SocketTimeoutException means the you can t connect read from source

Souhail Marghabi · Answer

That s the ip adtesse of the sender video streamer it is supposed to broadcast an UDP h264 video stream that the app then reads and displays

Olenyov Kirill · Answer

If your streamer is configured for broadcasting it means that it broadcast to the special addresses in IPv4 network 255 255 255 255 or 0 0 0 0 So in this case you should connect your player to one of this addresses

Souhail Marghabi · Answer

I think I phrased incorrectly the videostream comes from a Remote Camera equipped Device that that provides the server IP and a port number This info is retrieved on runtime through a rest call the results is always 192 168 1 103 NEW PORT

Olenyov Kirill · Answer

Are your all devices on the one local network Can you play this stream locally from computer using e g VLC player it can play network streams
