kandi X-RAY | agora Summary
Agora is a system that implements Markowitz Portfolio Optimization method (classical mean-variance technique). Harry Markowitz's 1952 paper is the undeniable classic, which turned portfolio optimization from an art into a science. The key insight is that by combining assets with different expected returns and volatilities, one can decide on a mathematically optimal allocation which minimises the risk for a target return – the set of all such optimal portfolios is referred to as the efficient frontier. It is extensible, and can be useful for a casual investor giving initial insights through as a serious Financial Instrument Analysis or Portfolio Management. The software relies on Yahoo Finance! to download the most recent trends in asset performance. Head over to the report to get an in-depth look at the project.

QUESTION
currently I am using Agora Web SDK NG for video call implementation on web. I have one theoretical question. I started work on screen share. I will use example. I have video call members A and B. User A starts a screen share. Sharing is working fine, but problem occurs when user A wants to stop the screen share. User A click on standard Agora Stop share button which is shown from the screen share beginning.
After click, sharing is stopped but this change is not reflected to user B. The current video stream from user A stucked, because the stream was not unpublished. And this is my main problem. On user A side, I am not able to detect the button click on Agora standard stop share button. This button is outside of browser context so I am not able to just make selector and create button click event. If I would be able to detect this button click, I am able manually unpublish the stream. Do you know how to do it? I would expect some event handler something like this client.on("user-stop-share", handlerFunction). I am using Google Chrome browser. Thanks.

Im using Agora SDK along with Flutter for a project, I have gone through the SDK Documentation but could not make out the requirement im currently having,
Lets say there is a channel with 100 Users and User modal is like
...ANSWER
Answered 2021-Jun-07 at 05:35The best way to do that would be to add uid in your user modal and then use the activeSpeaker callback provided in the SDK, activeSpeaker callback returns the uid of the user who is speaking currently and you can use that uid to display the user video or in your case the image of that user. Have a look at the documentation over here:activeSpeaker documentation

QUESTION
I am trying to import the Agora.IO modules from here to implement a screen sharing functionality. After cloning the repository at the provided link and adding it as a Module for my project, I am able to get all the imports correctly. The only imports that I needed were import io.agora.api.*, but the build fails with the following message.
ANSWER
Answered 2021-May-30 at 19:51The issue is exactly mentioned in the message. Gradle cannot resolve com.github.agorabuilder:native-full-sdk:3.4.2 dependency in any of the repositories that were added in the module.
Did you have jitpack repo defined there?
QUESTION
Assuming I integrate Agora in my website (PC + mobile hybrid app that wraps a mobile-web site). Will it be able to listen for users joining a channel while the client is not browsing the website? Meaning, can it work inside a service worker on both PC and mobile?
I need a reliable way to have voice calls between users on my web application even when they are not using the website.
...ANSWER
Answered 2021-May-25 at 10:04If you create a WebView or just open an iframe of the website then the user's video is turned off when the app is closed even if the microphone permissions are off.
The user is still on call and can track people joining but as soon as you close the browser, your video stream disappears for the other users.
To have background based workflow, I recommend you use the native SDKs for the app as well as desktop applications and implement them with the same App Id to maintain consistency.
An alternative solution is to use the RTM SDK as the RTM SDK allows you to send messages even in the background if the user is logged in and has joined the channel.

...ANSWER
Answered 2021-May-19 at 17:08The most common problem for this type of behavior is that you are using react-native on an android emulator. Android Emulator is using an IP-address different from localhost on windows machine Documentation
So you can forward your port on the same port used by the android emulator (10.0.2.2) or you can change the port to 80 so you won't have any problem You can go check this answer here
QUESTION
I am facing a strange problem with RN agora, When I start a video call on iOS everything works fine but when I pass my app to background and re-open it the audio doesn't work anymore in foreground mode. Even if I end the call and join again the channel only background audio worked fine. I cannot understand why.
If someone could help please ?
Thank you in advance.
...ANSWER
Answered 2021-May-18 at 09:43I finally found the problem:
I am using react-native-video for my welcomescreen background which is muted.
It is this prop : ignoreSilentSwitch='obey' which was causing the problem.
It can maybe help someone else.
