flutterjanus / flutter_janus_client Goto Github PK

Hi @shivanshtalwar0 , So i took your advice on rtp forwarding the video room for live streaming. But I hit a snag. I am probably not using the flutter_janus_client properly. But here's what I am trying to do. Setting up the RTP forwarding needs room id and user id as seen here https://ans.disi.unitn.it/redmine/projects/peerstreamer-ng/wiki/Few_notes_on_Janus_and_its_streaming_plugin , Now the room id is already known, since i created the room with id 5555, but user id is proving problematic. I tried this piece of code

var users ={"request": "listparticipants", "room": 5555};
plugin.send(message: users, onSuccess: (){print("MILADMIN list participants");});

But I keep getting this error at backend saying Invalid request on unconfigured participant. After some searching I think i am placing the above code in the wrong place. I have tried placing it inside different 'onSuccess(){}' but keep getting same error.

So where should I place the above code, so that it runs after I have joined the room as publisher ? Also where should I place the code for streaming ? I am currently placing it inside the j.connect after the j.plugin(videoroom) ends. Do I need a new j.connect for j.plugin(streaming) ? Thanks in advance.

Hi!

I faced with some problem when I want to close the stream session.
After some interval I keep recive this messages:

I/flutter ( 7607): keep live ping from rest client
I/flutter ( 7607): keep live ping from rest client
I/flutter ( 7607): {"janus": "error", "transaction": "dd39899f-6321-4c19-b586-867912e139e1", "error": {"code": 457, "reason": "Unhandled request 'keepalive' at this path"}}
I/flutter ( 7607): {"janus": "error", "transaction": "8a6786a4-08da-4c42-8c15-051a78f620e1", "error": {"code": 457, "reason": "Unhandled request 'keepalive' at this path"}}

But the "destroy" or "hangup" event on JanusClient has already been called.
What can I be missing?

Thank you

Hi @shivanshtalwar0 , this isn't an issue with the repository itself. Need some help with setting up a live stream. I have tried using your video room example and modified it to create a live stream on one end and view it on another, so two files. Sadly on the viewing end, for some reason the stream isn't getting listed. So I tried using the pre existing Janus Id 1 stream. Still didn't work, no video received.
I think this might be due to my lack of understanding on streaming using webrtc and Janus. Can you please give me a rough idea on how to proceed. Any help would be much appreciated. Thank you.

Hello,

Thanks for this wonderful work. I've tried the example and got it working, but little confused about how to get specific width / height from the renderer inside RTCVideoView?

What I want to achieve is to make Local Renderer video box appear always on most bottom-right of the screen (the example will have some empty space on the right side because Container has fixed width and not respecting video aspect ratio.

I have a Janus Server only accessable with https

How can this be implemented?

I'm trying to create a sip client app and I cannot find an example on the latest version. Is there a particular reason that is missing?

1. One calls initializeMediaDevices with useDisplayMediaDevice set to true
2. This will trigger an adhoc permission request, which can be denied by the user.
3. If the user denies the permission request, getDisplayMedia will fail

This is not catched within the function, resulting in a crash.

I guess the same holds if permissions for getUserMedia are not granted, most apps check these at startup. With mediaprojection/screenshare this is not possible on newer android versions.

Two solutions:

1. Adjusting the function
2. Placing the initializeMediaDevices call in a try catch (Examples should use try catch as well).

The second solution could be the better one, as it enables the developer to catch the exception, but it needs to be documented.

I'm using Flutter on top of the native iOS application. According to this documentation, I'm inserting it like "Embed frameworks in Xcode".

Next error xCode throws: https://prnt.sc/zu7pbq
Only happens when AppDelegate.swift file has next code: GeneratedPluginRegistrant.register(with: self.flutterEngine);
https://prnt.sc/zu7vhh

Also I'm able to solve it with WebRTC from Cocoapods dependency, but this looks like not good way.

Android is fine.

Also iOS works fine until it's not integrated to native code (another app)

Hi all,

I tried to run video_room example for Android and Ios. In Android system, my sample build, however in Ios, but I get this error:

@shivanshtalwar0 I was trying out the videoroom v2 example, and kept facing the following problem:

1. when using 3 virtual phones on my pc, each device only shows 2 videos, one from localrenderer, and another from one of the two other devices. Sometimes one of the device is only showing the local video.
2. when using 2 virtual device, and 1 physical device, one of the virtual device shows all 3 streams, but the other virtual device and physical device only show localrenderer.

The only change to the example code I have made is the Janus url, which points to my gcp server, which hosts janus, and the username while registering so all three devices have different usernames.

My understanding of Janus and webrtc isn't really that deep, so do I need change or add something else in the example code ?

hello @shivanshtalwar0
I have implemented the Janus plugin for the audio and video call feature. All the feature is working fine but I want to add one more feature when the application is closed or the background incoming call is not working what I do. have you implemented anything else for this.

Hi, I've been trying to use this plugin on iOS and then I got error like shown below.
Even when I run example code, I got same error.

Are there any solutions for this??

How to reproduce

Run example code of the repo.

What I tried, but it didn't work

  • Delete .pub-cache/hosted folder

Can you provide a flutter V2 version of the demo with null-safe?
The demo of "flutter_janus_client/example/lib/VideoRoom_V2.dart" isn't null-safe, and it run errors

Great project!!

Are you planning to support unified plan?

Hi @shivanshtalwar0 , I had a doubt with regards to Janus gateway, while reading the whatsapp security whitepaper. Is the video room secure or does it need some kind of additional encryption ? I tried searching for srtp in the janus documentation but it is available only for rtp_forward, and not for creating video room.
I am not really well versed in either Janus webrtc or srtp, and am using your example code as the basis of my project. Does Janus use srtp internally or is secured in some other way ? I am trying to make it end-to-end encrypted.

Hi,
This is not an issue but info request.
I have an application that works with freepbx voice central. everything works fine while app is in foreground. now I want to add voip notifications so that app can receive even if app is totaly closed.
in janus gateway I dont kill session and its active. when I call reconnect function when new call from other extension and its in ringing state; this function claims session but reconnect function creates new handle id and new call cant be received by app.
I just wonder if any logic to receive current call when app starts. any idea will be appriciated.
thanks.

Although this construction is present in the Dart language, it is not recommended for linking/importing files within the same library.

Also, it does not allow intellisense to check properly, potentially resulting in poorer code.

part of is actually nothing more than a placeholder construction, equivalent to putting everything in one file.

https://dart.dev/guides/libraries/create-library-packages

I guess should restructure according to the guidline.

A big advantage is that a developer using the plugin will only have to include the code regaring the janus plugin it is using. Resulting in a smaller appsize. Currently all janus plugins are included.

This potential breaking for current implementations. So propably something for a next major version.

It seems that username is mandatory.

Hello,
First of all, @shivanshtalwar0, thank you for taking the initiative to bring the Janus to flutter!
A quick question: I'm trying to run some tests locally and at this moment I don't own a turn or a stun server. Once 'iceServers' are mandatory, is it possible to use JanusClient constructor like this:
JanusClient(iceServers: [], server: [
'https://my _local_ip/janus'
], withCredentials: false);
?
Another question: I'm using an Android phone to debug and I'm also experiencing what was mentioned here:
flutter-webrtc/flutter-webrtc#126
Can this being happening because the connection to the server is failing? If not, what other problems may cause this?

Thanks in advance!

Support is almost ready to be tested examples still need lot of polishing but library is working great so far
Potential issue is with flutter_webrtc we need to introduce RTCAudioRenderer for playing audio track independently

I am having some trouble with multistream. Are the steps the same as normal streaming ? I want to broadcast the streams from videoroom with 3-6 members . So I need to rtp_forward the the room to a multistream mountpoint ? How exactly should I go about it ? I have tried creating a multistream mountpoint with both audio and video in media, but it doesn't show up in the drop-down in the streaming example, only showing the default 3. Need some help with implementing.

Janus VideoRoom does not require that the roomId is of type int. It is allowed to use strings instead if the option: string_ids is set to true.

Holds also for all participants uuid.

Hey, so great work on getting this far. I'm having a bit of trouble getting the project going or importing it in to a new one. I am on flutter master channel.

What's curious, I can see you are running it on Android. So I install.the app. Give the permissions manually to the camera and mic from the app settings. And then hit the call button. Nothing happens.

When I run it from iOS. I get a websocket connection. Can see the session /.IDs all created. But the app crashes.

So just wondering if I'm doing something specifically wrong. My server is already setup and running electron / browser peers via Websockets / HTTPS API

I'd like to help or fork from this project. So any insight would be awesome.

Thanks
Jay

The createOffer method within the publishMedia gets audioRecv: false, audioSend: true, videoRecv: false, videoSend: true as input.

This should not be fixed value, but dynamic, based on the provided media. It is common to send only a videotrack during a screen share.

Tested on Example app and implement in my App too.

When trying Android to Any Platform -> Audio input and output both are working fine.

When trying iPhone to Any Platform -> Audio input is not working but output is working fine.

Non-nullable instance field 'publishVideo' must be initialized.
Try adding an initializer expression, or a generative constructor that initializes it

The library 'package:janus_client/Plugin.dart' is legacy, and should not be imported into a null safe library.

Can you please help me to mute audio in remote feed. When I use getAudioTracks()[0] and I set enabled = false, I get error:
"You're trying to mute a remote track, this is not supported"
Any idea how to do it?

Firstly. Thank you for this huge work which you did!

I use this library for stream and when I want close my session I call janusClient.destroy() method, but still get a messages:

I/flutter (13515): polling active
I/flutter (13515): _eventHandler
I/flutter (13515): [{janus: keepalive}]

I/flutter (13515): Got a keepalive on session 6432391342667273
I/flutter (13515): Long poll...

Am I missed something?

Could not build the application for the simulator.
Error launching application on iPhone 12 Pro Max.`

When we start a stream, the sound goes to the "in-call" volume control.
Is it possible to route audio to the "media" volume control? Interested in such an opportunity on Android devices.

Thank you

You don’t hear the other person speaking at all in a video call. I tested video calls from iOS phone to Android phone and vice versa but don’t hear the other person on the call. On the other hand, the test was successful on one Android to an Android phone, though on some other android phones the sound was not working also.

I have this weird problem....when I use HTTP everything goes well the keep alive is pinging and fine But when I use websocket....i connect and everything goes well but after 60 seconds (Defualt janus timeout) the session get terminated..(session timeout)...

if i switch to HTTP everything is fine so i think and i can HTTP sending those keepalive packets....is anything wrong

I am trying to build an example for iPhone the Pod Install fails. The output of flutter run is enclosed:

How to implement mute unmute feature in audio room there is no method implemented for mute unmute and indicate other users who is muted.

Directories en filenames should be having the following format: lowercase_with_underscores

https://dart.dev/guides/language/effective-dart/style

I Have to use Janus client for audio and video calls when I disconnect the call I have cleared all the objects and disposed of video rendering but logs are always shown in consol how to fix that

EglRenderer: Duration: 4003 ms. Frames received: 0. Dropped: 0. Rendered: 0. Render fps: .0. Average render time: NA. Average swapBuffer time: NA.

when i toggle video off from one of the publishers the RTCVideoView() freezes his video , how can i track when some1 turns off his video so i can update the ui accordingly ?

A field called pin is missing as optional field in joinPublisher. Is required if a room has been created with a pin.

[ERR] [plugins/janus_videoroom.c:janus_videoroom_access_room:3955] Missing mandatory element (pin)

I will try to provide a PR later this week.

Hi @shivanshtalwar0 , I am getting the following error when running the videocall and videoRoom example on android device. However on making the call, the call doesn't reach the other device. This is the error I am getting :

I think it might be related to the fact that jsep is null as seen from here:
print('publisheronmsg : $msg, jsep : $jsep');

publisheronmsg : {videoroom: joined, room: 1234, description: Demo Room, id: 5268502155221207, private_id: 2581568118, publishers: []}, jsep : null

Can you please help out with this ?

Unified stream works fine
https://flutterjanus.github.io/flutter_janus_client/example/build/web/#/streaming_v2_unified

Chome info:
Version 96.0.4664.110 (Official Build) (x86_64)

So, should we all now switch Janus settings to Unified plan? According to this link Plan-B wouldn't be supported by Chrome.

2. On Firefox both kinds of streams work fine.

3. On Safari Streams doesn't work at all.

There is a small question.

What version of Janus JS was this module ported from?

I use v0.4 with success.
I try to implement v2.2.0 in new app but i successfully send my video/sound but i never received the video/sound from it.
