Hi, I tried kurento-rtsp2webrtc in LAN and then found that the video has very low resolution.
By the way, CPU consumes very low.

When I try running from docker I get this error and the stream does not load ?

WebSocket connection to 'ws://localhost:8888/kurento' failed: Connection closed before receiving a handshake response

Hello,
Just downloaded this demo to try out. I get an infinite loading bar on the web player. I have tried both firefox and chrome. I get some output errors from my http-server such as....

"GET /bower_components/adapter.js/adapter.js" Error (404): "Not found"
"GET /bower_components/kurento-client/js/kurento-client.js" Error (404): "Not found"
"GET /bower_components/kurento-utils/js/kurento-utils.js" Error (404): "Not found"

What am i missing? Thanks!

I dont understand this line of the readme document:

"Then, in each demo folder execute this command:"

Can anyone help me?

I think the kurento-media-server must be transcoding because the CPU load is 50% - is there any way to show the original H.264 video from the rtsp camera over webRTC without transcoding?

EDIT: Adding pipeline.create("PlayerEndpoint", {uri: address.value, useEncodedMedia: false} seems to have no effect :(

I need to show a loader while stream form ip cam is buffering as video quality degrades too much and video starts to stutter.
I have googled a lot but found nothing. Please suggest any method to show loader before video stutter.

Поток есть, но он не корректно отображается, с другими камерами все прекрасно работает, скажите куда мне надо смотреть что бы решить мою проблему?

Browser not receiving the video stream and player remains stuck in loading gif state.

Tried to setup TURN server (Node-turn & coturn) and ice server as follows -

ws_uri: 'ws://' + '107.108.207.92' + ':8888/kurento',
ice_servers: '[{"urls": "turn:107.122.13.15:3478", "username": "optional-username", "credential": "auth-token"}]'

Master branch throws below exception with ice_server.
urentoUtils.WebRtcPeer.prototype.server.iceServers = JSON.parse(args.ice_servers);

"cannot find server of undefined"

Release 5.1 accepts TURN config but RTCPeerConnection doesn't return any object

this.pc = new RTCPeerConnection(server, options);

Console shows below message -

Created SDP offer
Local description set
ICE negotiation completed
SDP answer received, setting remote description
PlayerEndpoint-->WebRtcEndpoint connection established
Player playing ..

Kurento media server examples based on MAVEN and spring boot are working on my system but rtsp2webrtc fails.

Queries -

1. Is TURN server needed ? Is TURN server supposed to be installed on the same system as KMS. (MY KMS is installed on remote)
2. What will be ws-uri. Is it supposed to be same as KMS ? (ws://' + '107.108.207.92' + ':8888/kurento',)
3. What all configuration needed for TURN (config coturn/node-turn, ICE server on client, KMS config file)

Please help to resolve the issue. Thanks

Hi, I am new in this world and I need help to start this demo.

Running in Ubuntu 16.04 I has KMS running (checked with ps and netstat, it is ok) and I has the http-server running from the kurento-rtsp2webrtc folder.
The web app is running fine, using this url

http://localhost:8080/index.html?ws_uri=ws://192.168.19.173:8888/kurento

But when I click START I get the follow console result

Hi,

The video linked in the example (quoted below) does not exist anymore

it doesn't work when rtsp like 'rtsp://ip:554/pag://ip:cameraid:0:MAIN:TCP'.
test in hiKvison iVMS-8600.
who can help me?

What to input on set source URL?
example i put: rtsp://admin:[email protected]/37777
On console it keeps showing "reconnect server"

Thank before hand

It work in chrome74 version , but not work in chrome75 or heigher version, is it a bug?

can support http h264/AAC stream?

I have a problem with websocket connection

I don't understand why .

I have clone the project in visual sudio

install all the dependecy

the local server work well I load the HTML page on local server 192.168.1.4:8086

when when i put a stream url in the imput

I want to display a few IP cameras in my web project. I understand that I need PlayerEndpoint for each one of them, buy am I need to create a new WebRtcEndpoint to each one? or can I use only one WebRtcEndpoint for all the PlayerEndpoints? (just to clarify, I want to display video per camera)

Hi,

This looks very promising and I wanted to look into it more.
I got about 1-2 seconds delay compared to the original rtsp stream(when viewed by VLC).
Is it possible to improve this? Maybe reduce the buffer somehow?
I want to get to latency that is below 1 second.

I looked at the kurento-media-server logs and I got this exception:
** (kurento-media-server:835): CRITICAL **: gst_video_encoder_set_latency: assertion 'GST_CLOCK_TIME_IS_VALID (min_latency)' failed

Maybe it has something to do with the latency issue that I have?

Thanks!

How to open the page and play it automatically?

everything prepared, and no error. but no remote picture. the console log:

we have to access out side of local network but not working.

in local network working fine and for outside network we have to used turn server

how can i install ice server on windows.
reconnect to server
how can i fix it

Readme.md currently mentions parameter ws_url, while the code actually requires ws_uri.

Please, fix this. This might cause some trouble to unaware users.

Dear all,
I have an IP camera connected to my eth0 and I can see the UDP packets streaming by using Wireshark. Is there any way to know the source URL by means of Wireshark information?
I have tried rtsp://dest_IP (with dest_IP being the destination address of UDP packets that camera sends), but it does not work... I also tried rtsp://dest_IP/dest_port.

Any idea?

I have everything running and working but when I enter my rtsp url (which works in VLC) it says reconnect to server on a loop in the console. Can anyone help me fix this issue?

I have setup this project and the Kurento Media Server on a linux machine on my network (10.0.11.72)
When I try to connect this project with another camera, I'm actually getting the stream on the browser.

However, when I have tried to access the webpage of this project from my windows machine running on 10.0.10.230, I can connect to the webpage of this project when I access it using 10.0.11.72:8080.

However when I try to connect to the same camera, the camera stream doesn't appear on the browser. Are there any other config that was require for this implementation to work?

I have also tried

1. Disabling the Firewall of the Linux machine
2. Enabling the Firewall of the Linux machine and allow ports 8080, 8888, 9090, 9091
3. Added a proper set of TURN and STUN servers
4. Changed the config file of the Kurento Media Server with the following settings.

  "HttpEndpoint" : {
     "serverAddress" : "10.0.11.76",
    "port" : 9091
  },

Are there any other steps that I need to follow?

Hi, I got stuck in "Player playing" this is RTSP URl => rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov it works well in VLC, but when I try to use the URL, I got stuck in "player playing".

WebSocket connection to 'ws://localhost:8888/kurento' failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED

Tried both default URL and URL from my own IP-camera that works fine in VLC.

Fyi, getting this javascript error when running in Edge.

How to support H.265(HEVC) rtsp stream?

My question is: if I try to access this camera outside, how to do it? currently KMS server is inside.
