PlayerEndpoint to WebRtcEndpoint code

[Denis Syroezhkin]

Hello! I need help connect PlayerEndpoint to WebRtcEndpoint.

I try this code (java): 

private void start(WebSocketSession session, JsonObject jsonMessage) {

try {

// Media Logic (Media Pipeline and Elements)

MediaPipeline pipeline = kurento.createMediaPipeline();

pipelines.put(session.getId(), pipeline);

//initialization PlayerEndpoint

PlayerEndpoint playerEndpoint = new PlayerEndpoint.Builder(pipeline,

"rtsp://user:pass...@192.168.1.6:554").build();

                        //initialization WebRtcEndpoint

WebRtcEndpoint webRtcEndpoint = new WebRtcEndpoint.Builder(pipeline)

.build();

                        //Connect PlayerEndpoint and WebRtcEndpoint (PlayerEndpoint ---> WebRtcEndpoint)

                        playerEndpoint.connect(webRtcEndpoint);

webRtcEndpoint.connect(playerEndpoint);

                        //Start playback

player.play();

        String videoUrl = webRtcEndpoint.getUrl();

// SDP negotiation (offer and answer)

String sdpOffer = jsonMessage.get("sdpOffer").getAsString();

String sdpAnswer = playerEndpoint.processOffer(sdpOffer);

// Sending response back to client

JsonObject response = new JsonObject();

response.addProperty("id", "startResponse");

response.addProperty("sdpAnswer", sdpAnswer);

session.sendMessage(new TextMessage(response.toString()));

} catch (Throwable t) {

sendError(session, t.getMessage());

}

}

private void sendError(WebSocketSession session, String message) {

try {

JsonObject response = new JsonObject();

response.addProperty("id", "error");

response.addProperty("message", message);

session.sendMessage(new TextMessage(response.toString()));

} catch (IOException e) {

log.error("Exception sending message", e);

}

}

}

I use MagicMirror Tutorial, It is impossible to connect PlayerEndpoint, I've tried almost all of the examples, and look here http://www.kurento.org/docs/current/langdoc/javadoc/index.html and look here http://www.kurento.org/docs/current/mastering/kurento_architecture.html?highlight=sdp  I watched all the tutorials and documentation, but I can not connect PlayerEndpoint and WebRtcEndpoint. Please help me! Sorry for the stupid questions. But I really need your help!

P.S. Maybe you can give me a link where I should read the information or send immediately ready code (which I doubt) Thanks for the answer!

Remove webRtcEndpoint.connect(playerEndpoint); since you are creating a loopback

webRtcEndpoint.connect (playerEndpoint);

Of the log can be seen that the error in this line of code:

Maybe fix it?

String sdpAnswer = webRtcEndpoint.processOffer(sdpOffer);

Yes, you need to change that too. In any case, your IDE should have yelled at you, since the method processOffer is not available for playerEndpoint...

I suggest you take a couple of minutes studying the code, and really understanding what each component is for and how they are supposed to work together.

A couple of minutes? I did learn a month. I really need help, I have nowhere else to turn for help, did not see more forums devoted rival to

A better use RtpEndpoint?

What I want to do, perhaps?
