We have the crashes with our app which uses the agora video calls on the Android tables with Intel Atom processors (x86) (e.g. ALCO RCT6973W43 with Android 6.0.1).

Could you help us with this issue?

Can we please have the samples update with the latest sdk.

i have installed the video web call sample , to join call both parties should have to click on the join part and keep the channel value same . i wonder as it would be possible to generate direct video call link so that if user click on it the could start call with one another.

Platform : web platform ( php html js )

在我手机上可以安装成功，但发给其他人就显示无法安装（好像提示是系统不兼容）

在参考readme的设置后运行至iOS10.3.1系统的真机上，黑色窗口不出现画面，其他功能按钮是正常的，请问是什么原因呢

when build the sample code, it always report
Error 1 error C1083: Cannot open include file: 'IAgoraRtcEngine.h': No such file or directory c:\openvideocall-windows\openvideocall\stdafx.h

tried both VS 2019 & 2013.

I attempted to upgrade from 2.8.0 to 2.9.0 and without changing any of my underlying code I get the following error when Stream.init is called. Everything works fine when I use 2.8.0

I followed the Quickstart Guide but I'll include my sequence here.

client = createClient(this.config);

bindCallback(client.init)(appId)

bindCallback(client.join)(null, channelId, uid)

navigator.mediaDevices.getUserMedia({video: videoValue, audio: audioValue}))
    return from(navigator.mediaDevices.getUserMedia({video: videoValue, audio: audioValue})).pipe(
      flatMap(mediaStream => {
        that.videoSource = mediaStream.getVideoTracks()[0];
        that.audioSource = mediaStream.getAudioTracks()[0];
        specs.videoSource = that.videoSource;
        specs.audioSource = that.audioSource;
        const localStream = createStream(specs); 
        that.localStream = localStream;
        return bindCallback(localStream.init)();
      }),
 client.publish(this.localStream);

The error occurs when I go to initialize my localStream (localStream.init)

Other details that may be relavent.

• I'm wrapping all calls with RxJS bindCallback to return observables
• This code is part of a larger Angular 7 project.

Any thoughts?

Thanks!

Basic-Video-Broadcasting changed from WorkerThread into Application-inside codes.
That way is simple to understand and easy to implement it.
Could you please also update this sample such as new Basic-Video-Broadcasting sample?

Hi,

In https://github.com/AgoraIO/Basic-Video-Call/blob/master/Group-Video/OpenVideoCall-Android/app/src/main/java/io/agora/openvcall/ui/CallActivity.java
I understand that mGridVideoViewContainer contains the recyclerviews of surfaceview of new user's video on video call. I have read through the file and cannot find where mGridVideoViewContainer is being updated when new user joins the video call. I can clearly see that when mUidsList.put(uid, local) is called inside the function "onJoinChannelSuccess" but mGridVideoViewContainer is not updated.

Can you please tell me where mGridVideoViewContainer is updated when user joins group video chat?

Thank you.

Sincerely,
Victor

文档上有说是静态厂商使用了动态 Key，但是怎么生成静态Key?

Agora Web SDK 2.6.1

After calling stream.switchDevice() I can see the following error thrown in Chrome dev console:

Hi, Can you add Flutter Example for Basic-Video-Call and Basic-Audio-Call

Hi,

I went through the documentation but I couldn't find anything about switching the screens, what I need to do is load the first user that joins the call in the big canvas and move the current user in a small box.
Can you help me in what direction to take?

Thanks,
Bogi

Hi,
I read through the docs but I couldn't find any mentioning about how to turn off the camera after I end the call I all the following function but the camera is still left on.

 localStream.disableAudio();
    localStream.disableVideo();
    agoraClient.leave(
      function() {
        console.log("Leavel channel successfully");
        agoraClient.unpublish(localStream, function(err) {
          console.log("Unpublish local stream failed" + err);
        });
      },
      function(err) {
        console.log("Leave channel failed");
      }
    );

Thanks for any ideas.

How to replicate:

• Press the call end button and read the service leak message.

Devices tested on:
Pixel Android 9 API 28 - Can't reproduce.
Redmi 5A Android 7.1.2 API 25 - memory leak happens.

This is not necessary anymore since the tutorial has its own order in the readme.md.

Hi,

After updating the latest SDK 2.8.2 App get crashing.

cannot initialize Agora Rtc Engine, error=101

 Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'int io.agora.rtc.RtcEngine.setVideoEncoderConfiguration(io.agora.rtc.video.VideoEncoderConfiguration)' on a null object reference

If using 2.3.0 ist working fine.

please provide link for download only android code

In OpenVideoCall-Linux, it mentioned to download Linux SDK from Agora SDK website.
Unzip SDK and copy "libagora_rtc_sdk.so" to OpenVideoCall/libs folder.

But I can't find the Linux SDK zip from Agora SDK website.

https://docs.agora.io/en/Agora%20Platform/downloads

There are only Android/iOS/Mac/Windows/Web/Electron.
Does Agora voice/video call still support Linux?

See attached photos. When the video is initially displayed in the view, it covers only 1/4 of the view. When window is resized, the entire view is covered.

Hi,
I am using AgoraSdk for video call. We want to implement a feature to enable user switching between audio to video call and vice versa. But there is no documentation regarding that. Please help

Hi folks, currently I am looking for webhooks of the video call, I tried to do research but unfortunately can't find any info related to webhook.
How can I get a duration of video call after the end? for example, user can turn off PC and need a webhook to trigger me a duration of a call

I have created a channel using

`- (int)joinChannelByUserAccount:(NSString * _Nonnull)userAccount
                          token:(NSString * _Nullable)token
                      channelId:(NSString * _Nonnull)channelId
                    joinSuccess:(void(^ _Nullable)(NSString * _Nonnull channel, NSUInteger uid, NSInteger elapsed))joinSuccessBlock;` 

But when someone joined the same channel using account, then how can we find which user joined the channel by using account?

All delegate methods in documentation for remote stream requires passing uid, but since I am using account instead of uid, I am not able to match which user joined / left channel. Is there a way in which I can find which user joined/left the channel using account instead of uid ?

我这边新作的功能是拖动窗口，动态改变播放段，接收端的视频窗口大小，里面的surfaceView已经改变了，但是数据确不能及时的改变，导致有黑框？

When I click the "JOIN" button, the following error will occur

On the IOS Groupcall App Version, it asks for an encryption key and I don't know what to submit.

我参照项目 Basic-Video-Call / Group-Video / OpenVideoCall-Web 做了修改，教师用firefox共享桌面和语音，学生用电脑可以看到画面和声音。
但是在IOS12 iPhone6s上使用safari观看存在以下两个问题:

1. 学生只能看到画面，听不到声音。
2. 学生在iPhone6s上使用 safari浏览器调用 SDK的方法 localStream.init 方法之后没有回调。

localStream = streamInit(uid, options, config);
    // enableDualStream();
    localStream.init(
      () => {
        addStream(localStream, true);
        client.publish(localStream, err => {
          alert('error!'+ err)
          localLog('Publish local stream error: ' + err);
        });
      },
      err => {
        localLog('getUserMedia failed', err);
      }
    );

请问是不是Agora web SDK本身不支持手机上使用safari进行互动直播？

Hi,

Basic-Video-Call > Group-Video > OpenVideoCall-Android

I play the upper program with two different smartphones.
I test it in good network connect of both wifi and LTE.

But I get always the following error.
AGEventHandler.EVENT_TYPE_ON_APP_ERROR (No network connection, please check the network settings)

After install the web screen chrome extension and config the extensionID, there's still an error: "No response from Chrome Plugin. Plugin not installed properly".

We have a requirement, where we would allow user to start video call directly from Front/Rear camera with feature to switch Camera. Currently, RTC switches the camera but we couldnt find a way to check which camera is currently active on RTC stream

Everything works correctly on Android < 9, but on the Pie we have a problem: volume doesn't change at all. Even in Do not disturb mode sounds still playing.

Agora version: 2.3.0, devices: all phones with Android Pie

i followed all steps when i click JOIN button i get error

Agora-SDK [ERROR]: [9BA0E] Get server node failed [INVALID_VENDOR_KEY] https://ap-web-3.agora.io/api/v1 INVALID_VENDOR_KEY

i copied and pasted correct app id from my dashboard project

thanks

Hey team,

In src/utils/BrowserCheck.js within the OpenVideoCall-Web sub-repository, window.chrome.webstore is undefined. According to this StackOverflow post , Chrome 71 released on December 4th made this undefined.

Best,
Vivek

Hi,

We are following the steps mentioned here, https://github.com/AgoraIO/Basic-Video-Call/blob/master/One-to-One-Video/Agora-Web-Tutorial-1to1/README.md . We are unable to find the section on agora io dashboard where we can generate an access token. Please guide us in the right direction. We appreciate your cooperation.

Group video call.
When running the sample, with npm run dev, the following errors are reported in the browser console:
14: 08: 10: 704 Now-SDK [ERROR]: [100CC] User join failed [ERR_DYNAMIC_USE_STATIC_KE]
4: 08: 10: 720 Now-SDK [ERROR]: [88812] User join failed [ERR_DYNAMIC_USE_STATIC_KE]
Uncaught (in promise) ERR_DYNAMIC_USE_STATIC_KE
My environment is:
Windows 7
Node 11.11.0
Npm: 6.9.0
The example does not trigger the camera or even the sound.
How should I correct the reported errors?

设置了 320x240

• (void)setupVideo {
  [self.agoraKit enableVideo];

  AgoraVideoEncoderConfiguration *configuration =
  [[AgoraVideoEncoderConfiguration alloc] initWithSize:AgoraVideoDimension320x240
  frameRate:AgoraVideoFrameRateFps15
  bitrate:AgoraVideoBitrateStandard
  orientationMode:AgoraVideoOutputOrientationModeAdaptative];

  [self.agoraKit setVideoEncoderConfiguration:configuration];
  }

但在 firstLocalVideoFrameWithSize 中的size一直是960*720

• (void)rtcEngine:(AgoraRtcEngineKit * _Nonnull)engine firstLocalVideoFrameWithSize:(CGSize)size elapsed:(NSInteger)elapsed {
  NSLog(@"size : %d, %d", (int)size.width, (int)size.height);
  }

With 3 total participants (self + 2 remote), the layout of the tiles is displayed correctly.

When adding a 4th participant (self + 3 remote), the newly joined participant does not get displayed.

When adding a 5th participant (self + 4 remote), a third row is displayed and now ALL participants are displayed correctly.

When removing the 5th participant, 4 total participants are displayed correctly.

So the bug occurs when going from 3 to 4 total participants.

We are using PushKit for sending notifcations on iOS. When we call a user :-

1. The sender immediately logs in Signalling kit and Joins channel on RTC.
2. The receiver gets a pushkit notification, it shows a CallKIT UI and also logs in to the Agora signalling.
3. The receiver on accepting joins channel and updates the UI.

But if the sender cancels the call before the receiver can accept, and then receiver picks the call, there is a black screen.

Is there is a way to identify if used has cancelled the call?

We tried the delegate callback for RTC : didOfflineOfUid, but there is no callback.

In IOS, after going through all of the steps, I get this error:
