Integrated Voice and Video Troubleshooting

Roll20 is interested in bringing people around tabletop games. To facilitate that purpose, we've integrated video and voice chat. The purpose of this document is to provide assistance with troubleshooting if issues arise.

Integrated Voice and Video Bandwidth Requirements

Roll20's Integrated Voice and Video utilizes WebRTC. WebRTC requires native support in web browsers. Roll20 officially supports Chrome and Firefox browsers.

Integrated Voice and Video runs on a peer-to-peer framework which means that every additional player in a call will add to the bandwidth requirements for that game for a stable experience. For reference, Integrated Voice and Video should be able to handle a 5 person call on most systems.

Check Your Device

Always check your devices first for audio/video issues.

  • Check in a different browser (i.e. Firefox instead of Chrome)
  • Check with a different software (i.e. Discord, Google Meets, Zoom, etc.)

Check devices for audio/video issues to diagnose problems and potentially find immediate browser workarounds before further troubleshooting.

Check Audio and Video Settings 

For issues while you are in a call, first check the Audio and Video section in My Settings tab of the Right-side Menu.

Chat Tech

The GM should have Chat Tech set to Integrated Voice and Video selected. If Chat Tech is set to None (no video/audio) a call will not initiate connections between players.

If you are still using the Legacy Roll20 WebRTC option and are still suffering audio and video problems, we recommend swapping over to the more modern Integrated Voice and Video option.

Broadcast and Receive Settings

Check settings for "Others can hear or see" and "I can hear or see" to ensure individuals are not accidentally disabled.

Output and Input Sources

Check that the correct devices are being used for Audio Input Source (your microphone) and Video Input Source (your webcam). Note that the Audio Output Source drop-down menu is not available unless you have joined a call.

Check Camera Pause and Microphone Mute

On your portrait within the game, you can hover to see options appear for muting your microphone and pausing your camera. Ensure that neither effect is active by toggling them.

Attempt to Reconnect

Integrated Voice and Video offers two different ways to reconnect to a call: a global reconnect reconnects with everyone else in the call simultaneously, while an individual reconnect restarts individual connections.

If you are requiring a reconnect it is typically indicative of a network level issue. It may take a few attempts to succeed in a reconnect. If you are still having trouble after a few tries proceed to the Network and Bandwidth Settings section.

Individual Reconnect

To reconnect with one person in a call, click the "reconnect" button in the top right of their portrait. This will cause the connection to refresh between both of you.

Global Reconnect

If you or a player are having issues seeing or hearing multiple people or everyone within a call you can use the Global Reconnect option to simultaneous refresh those connections. To do this navigate to the Settings tab of the Right-side menu and expand the Audio and Video section; once here, you can click the Reconnect button.

Refresh the page

Refreshing the page mimics reconnects and resolves potential transient issues. You can also attempt via "Shift+F5" which allows for a page reload while clearing the cache for the page.

Browser Settings

At present, we fully support the most recent versions of Firefox and Chrome web browsers for our VTT. Other browsers may be able to handle Integrated Voice and Video with little to no issues, but we can't guarantee you will not encounter any issues.

Check if the site/tab is muted

While on the VTT, right-click the tab to access the context menu. Ensure that the Mute Site/Tab option is not enabled. Mute Site/Tab it IS enabled, you will need to select the option Unmute Site/Tab.

Check your browser audio and video permissions

When the VTT loads for the first time, you will be asked to Allow or Block permissions. Selecting Allow should enable your devices to be used within a Roll20 game/call. The below outlines what to do if you previously blocked permission or it were not prompted.

Chrome Permissions
  1. Select the "Lock" icon on the left side of the URL/search bar.
  2. Ensure that Camera and Microphone are toggled to "on."
  3. Reload the page.

Unblock WebRTC (VPNs/Browser)

Roll20 utilizes a peer-to-peer WebRTC system to enable Integrated Voice & Video.  If you are having trouble connecting, it may be that you are hiding or preventing WebRTC from accessing your IP address. In order to properly connect to everyone within a call you must ensure that WebRTC is not blocked.

VPNs

If you are using a VPN, we recommend trying the following options:

  • Ensure that roll20.net and app.roll20.net are allowed within your VPN for WebRTC access.
  • Disable WebRTC blocks within your VPN.
  • Disable your VPN.

Browsers

If you are using Chrome and are blocking WebRTC, it is most likely through the use of an extension such as "WebRTC Leak Prevent". In these cases we recommend disabling this extension while attempting to use Roll20's Integrated Voice and Video.

If you are using Firefox, you can follow these steps:

  1. Navigate to "about:config" via your address bar.
  2. Click "Accept the risk and continue".
  3. Click "show all".
  4. In the search bar, enter "media.peerconnection.enabled".
  5. Ensure that the setting is set to "true" via the toggle on the right hand side.

Hardware Acceleration and Video Encoding

Enable Hardware Acceleration in your browser by following these steps.

Enable Hardware Acceleration within Chrome:

  1. Navigate to "chrome://settings/system" in your URL bar.
  2. Ensure the setting "Use hardware acceleration when available" is enabled.

Enable Hardware Acceleration within Firefox:

  1. Navigate to "about:preferences#general" in your URL bar.
  2. Scroll to the "Performance" section.
  3. Ensure the setting "Use hardware acceleration when available" is enabled.
  4. To check this, you may need to check/uncheck the "Use recommended performance settings" option.

If you are still having issues, you may need to check and toggle your browsers Video encoding settings.

To check Chrome:

  1. Navigate to "chrome://gpu/" in your URL bar.
  2. Under "Graphics Feature Status" at the top, check the "Video Decode" and "Video Encode" settings -- they should both say "Hardware accelerated".
  3. IF "Video Decode" says "Disabled" go to chrome://flags/#disable-accelerated-video-encode  and toggle the setting.

To check Firefox:

  1. Navigate to "about:support" in your URL bar
  2. Search for "HARDWARE_VIDEO_DECODING", "VP8_HW_DECODE" and/or "VP9_HW_DECODE"
  3. Ensure they are set to "Default" and/or "Available"
  4. IF they are not available, Navigate to "about:config" via your address bar
  5. Click "Accept the risk and continue"
  6. Click "show all"
  7. In the search bar, enter "media.hardware-video-decoding.enabled"
  8. Ensure that the setting is set to "true" via the toggle on the right hand side

Network and Bandwidth Settings

Perform a Bandwidth Test

Bandwidth usage for Integrated Voice and Video can vary based on a variety of factors such as Browser, hardware, connection, etc.. Roll20 recommends that you use high-speed internet (Cable or better) while utilizing Integrated Voice and Video.

You can take a bandwidth speed test from OOKLA’s Browser-based Speedtest. You will want to run this test in the usual environment you normally play your games on Roll20 and have a Roll20 game currently open.

  1. Once Speednet's home page loads, click the central "GO" button.
  2. Run the test. This process can take a couple minutes to complete.
  3. Once the test is finished, Speedtest will give you your download and upload rate in megabits per second (Mbps).

If you are noticing that your bandwidth is low or you are still seeing some general slowdowns you may need to try the following:

Change your settings

In cases where performance or bandwidth are a problem, a quick solution is to disable the video portion of the call. You can do this by navigating to the Audio and Video section under the My Settings tab of the Right-side Menu; From here select Voice for both Others can hear or see and I can hear or see. This will limit the amount of bandwidth that Roll20 will attempt to use at one time.

Attempt via a different connection

Sometimes using a different device or connecting via ethernet as opposed to wireless can make a large difference.

Check security or VPN settings

Some VPN services can have an impact on internet speeds which may impact your experience while in a Roll20 call. We recommend experimenting with these settings to find what works best for your game.

Contact your ISP

If your internet speeds are insufficient for Integrated Voice and Video or lower than advertised, consider contacting your ISP directly for a solution.

WebRTC Compatibility Test

Alternatively is to run a test of your webcam and mic through whereby.com. This website is also a Peer-to-Peer WebRTC service that can have up to four users in a conference call.

Filing a Bug Report

If none of the above helped to resolve your issues, please contact our customer support here.

Be sure to include information on the steps you have taken so we can continue from there. Further, please provide the following information:

  • Operating System
  • Browser and Version
  • Any VPNs Currently Enabled
  • Description of the Issue
  • WebRTC Debug Log (Click the "Download WebRTC Debug Log" button under the Audio and Video section of the My Settings tab)
