• FFMPEG remote IP camera over RTSP h.264 format to HLS Localhost m3u8 format [closed]

  25 juillet, par macmeyers50

  I'm trying to convert the remote IP camera over RTSP to a localhost HLS format so that I can display it in a UI. I'm using a java library that only supports HLS over HTTP not remote IP camera.

  



  I'm under the impression FFMPEG can do this because I can write the HLS file just fine directly to my disc but when I change the target to something like http://localhost:8080/stream.m3u8 it cannot seem to connect to localhost.

  



  Below is my attempted FFMPEG command (IP/User/Pass left off) but I know that it can at least connect and read the RTSP camera fine.

  



  ffmpeg -i rtsp://[Username]:[Password]@[IP]/axis-media/media.amp?videocodec=h264 -rtsp_transport ffplay http://localhost:8080/media.m3u8


  



  The error I'm getting back is Connection to tcp ://localhost:8080 failed : Error number -138 occurred

  



  I thought that ffmpeg could handle hosting the file on localhost itself. FFServer is deprecated and removed but according to documentation it can still kick up a server just fine

• i am trying to make my ipcamera stream over webrtc usingnodejs and kurento media server

  5 mai 2023, par vishnu nair

  i am new at webrtc and rtsp, while trying to make a project on webrtc i came to a halt in my code and after weeks of online search adn usng chatgpt am still not able to resolve my problem. I want to stream my ipcamera to webrtc but the code is not working properly.am not above to start the stream.

  


  the code is given below

  


  const wrtc = require('wrtc');
const kurento = require('kurento-client');
const mqtt = require('mqtt');
const node_ffmpeg_stream = require('node-ffmpeg-stream');

const mqttonline_connection = require('../../mqttconnection/online_mqtt_connection');
const clientonline = mqttonline_connection.returnconnection();
const topiconline = mqttonline_connection.topic;

const RTSP_URL = 'rtsp://admin:password@192.168.0.100:554/Streaming/Channels/101?transportmode=unicast&profile=Profile_1';

async function startStreaming() {
  try {
    // Create Kurento client and pipeline
    const kurentoClient = await kurento('ws://localhost:8888/kurento');
    const pipeline = await kurentoClient.create('MediaPipeline');

    // Create WebRTC endpoint
    const webRtcEndpoint = await pipeline.create('WebRtcEndpoint');
    webRtcEndpoint.setMaxVideoRecvBandwidth(10000000); // Set max bandwidth to 10 Mbps

    // Create RTSP source and connect it to the WebRTC endpoint
    const rtspEndpoint = await pipeline.create('RtspEndpoint', {uri: RTSP_URL});
    rtspEndpoint.connect(webRtcEndpoint);

    // Start streaming
    webRtcEndpoint.gatherCandidates();

    // Subscribe to ICE candidate events and send them via MQTT
    webRtcEndpoint.on('OnIceCandidate', event => {
      const candidate = kurento.getComplexType('IceCandidate')(event.candidate);

      clientonline.publish('sdp', JSON.stringify(candidate));
    });

    // Subscribe to ICE connection state events and log them
    webRtcEndpoint.on('IceConnectionStateChanged', event => {
      console.log(`ICE connection state changed to ${event.state}`);
    });

    // Generate SDP offer and send it via MQTT
    const sdpOffer = await webRtcEndpoint.generateOffer();
    clientonline.publish('sdp', JSON.stringify(sdpOffer));

    // Start the RTSP source
    rtspEndpoint.play();

    // Listen for incoming SDP answers via MQTT and set them on the WebRTC endpoint
    clientonline.subscribe('answer');
    clientonline.on('message', (topic, message) => {
      if (topic === 'answer') {
        const sdpAnswer = JSON.parse(message);
        webRtcEndpoint.processAnswer(sdpAnswer);
      }
    });

    // Listen for incoming ICE candidates via MQTT and add them to the WebRTC endpoint
    clientonline.subscribe('candidate');
    clientonline.on('message', (topic, message) => {
      if (topic === 'candidate') {
        const candidate = JSON.parse(message);
        webRtcEndpoint.addIceCandidate(candidate);
      }
    });

    // Handle errors
    webRtcEndpoint.on('Error', error => {
      console.error('WebRTC endpoint error:', error);
    });
    rtspEndpoint.on('Error', error => {
      console.error('RTSP endpoint error:', error);
    });
    pipeline.on('Error', error => {
      console.error('Pipeline error:', error);
    });
  } catch (error) {
    console.error('Error starting streaming:', error);
  }
}

startStreaming();


  


  am getting the error as
