WebRTC Related FAQ

Can I check the existing chat history when joining into the meeting?

The existing chat history is only visible if the user rejoins the same meeting via the same browser using the same name and Email address.

How can I become the meeting host when using WebRTC?

To become the meeting host when using WebRTC:
Step 1: Please obtain the host code from the scheduled meeting. Log in to the IPVideoTalk Portal->Meetings. The host code can also be found in the notification email that states “You have a meeting to host”. 
Step 2: While the meeting is in session, from the meeting information page, click on “Host meeting”, and enter the 4-digit host code to become the meeting host. 

How can I use an external audio speaker or microphone instead of my computer’s built in options when joining the meeting via web browser?

When using Google Chrome: Google Chrome supports hot swapping. This means that users can simply plug in the external audio device, and it will be automatically used for the meeting.

When using Firefox: Before the meeting begins, plug in the audio device that you want to use. Once the device is plugged in, open the Firefox browser and press F5 to refresh your web browser to use the external audio speaker or microphone.

How come I cannot see the list of participants during the meeting?

This means the meeting host disabled the public listing of attendees. The “Display Attendees List/Status” option is automatically disabled, and it cannot be enabled during the meeting.

I can see duplicate attendees on the “Participant List”, why?

This is the effect of a connection protection measure by IPVideoTalk server. When WebRTC client loses connection and exits the meeting abnormally (usually caused by unstable network), IPVT server will keep the current connection for about 1 minute until it receives reply from the WebRTC client. Otherwise, it will terminate the connection and kick the client out. During this period, there will be duplicate attendees on the participant list while the WebRTC client re-joins the meeting on a new tab.

I cannot find the option to share system audio when sharing desktop or application. What could be the problem?

The feature "share system audio" works differently on different computer platforms. When used on Windows PC, the entire system audio can be shared. However, when used on Linux and macOS, only the audio from the browser tab can be shared. Please note currently "share system audio" feature is supported on Chrome and Edge browsers only.

 

I cannot see video during the meeting on my web browser, why?

If the network condition is not stable, the video might take longer than expected to load. Please check the following:
Confirm that the network status is stable. Use speed test tool such as https://www.speedtest.net/ to confirm that your upload and download speeds are as expected. Check for packet loss by clicking on the “Settings” button on the bottom left of the web page. After confirming the above, refresh the web page and rejoin the meeting. 

I do not see the meeting host, but the meeting is still going on?

If the meeting host leaves the meeting, but does not end the meeting, the meeting will continue like this.

I have installed the IPVideoTalk plugin on Safari, but the plugin requirement page still shows up after restarting the browser, what should I do?

Please make sure you have enabled IPVideoTalk plug-in when the permission request window pops up. If no window pops up (known issue when using IPVideoTalk on Safari v10.0+), please follow below steps to resolve the issue:

1. Choose "Safari"->"Preferences".

2. Click on "Security", make sure "Allow Plug-ins" is enabled.

3. Click on "Plug-in Settings" and select "IPVideoTalk" plug-in from the list on the left side.

4. For "meetings.ipvideotalk.com" plug-in, change the option from "Ask" to "On".

5. Restart the browser to join the meeting.

The plugin “sharing screen/application plugin” cannot be installed on my web browser, why?

1. Your web browser might not allow you to access the plugin. Please set “Allow” by going to your web browser settings to enable the components.
2. Your web browser may be outdated, please upgrade to the latest version.
3. Ensure that you are not using “Privacy” or “Incognito” browsing mode when trying to install the plugin.

What is the recommended version of WebRTC browsers that clients can use, 32-bits or 64-bits?

Please refer to below chart for the required minimum bandwidth to ensure proper function of audio, video and screen sharing during an IPVideoTalk Web Meeting.

When I join the meeting from WebRTC using Safari as the browser, the web page always asks me to install plug-in. This happens even after I downloaded and installed the plugin. How can I join the meeting using Safari successfully?

When using Safari on MAC OS as WebRTC client, after installing the plug-in, please make sure to restart the browser manually by clicking on Safari icon on “Dashboard” and selecting “Quit” in the pop-up menu. Then you can open Safari again and use the meeting link to join the meeting.

When I use "Split Screen" option on my browser during IPVideoTalk meeting and other participant is sharing screen, I cannot see the content being shared and the sharing screen is black. How can I fix this?

This is caused by hardware decoding issue with H.264 on Chrome and Edge browsers. To resolve the issue, the user can open Chrome/Edge browser and enter "chrome://flags/#disable-accelerated-video-decode" or "edge://flags/#disable-accelerated-video-decode", and set "Hardware-accelerated video decode" as "Disable".

When the presenter is sharing the screen, I cannot see presenter’s PowerPoint pages being updated from my web browser. Why?

The presenter needs to make the PowerPoint full screen on the local PC before sharing the screen. Once the PowerPoint is in full screen then start sharing the screen, the participant should see the PPT page updating.

When trying to share presentation using WebRTC, after installing the add-ons and clicking on "Share", content sharing will not start, and the browser shows the prompt asking me to install add-ons again. What should I do?

Please make sure you are not using "Privacy" or "Incognito" browsing mode when installing the add-ons on your browser. 

When using Windows 7 and Firefox, I get about 1% video packets loss, how is this resolved?

This is a compatibility issue with Firefox. You may click on icon "EnhanceWindowBuffer.reg" to download and run the registry file on your PC. After downloading it, restart your PC.
