Video
SignalWire Video is a powerful WebRTC video conferencing tool built on an MCU (Multipoint Control Unit) that handles all the muxing in the cloud. A single unified stream is sent to each participant, resulting in low latency, high quality, and the same video stream for all users.
Use classic HTTP calls to create and maintain tokens, rooms, sessions, and recordings.
Build a video solution using your own server with web socket technology.
Make audio/video calls to phone numbers, SIP endpoints, and other browsers.
Frequently asked questions
Can I programmatically create rooms and control attendee permissions?
Yes. Please check out our API reference to see how to create a room with a prebuilt UI (a Programmable Video Conference) with a room without a prebuilt UI.
How long can room names be?
Room names can be up to 100 characters, with a display name of up to 200 characters. Be sure to avoid using ”/” in room names.
How can I define user permissions?
You define a user’s permissions for a room when you generate their access token. See the room_tokens API endpoint. Access tokens for Programmable Video Conferences are generated when the conference is created. The response object includes tokens for moderators and guests. Guest tokens will only have permissions to modify their own settings while moderators can effect their own settings, room settings, and settings for other participants.
Do video tokens expire?
No, by default all tokens will last indefinitely. You can alter the lifetime of your tokens using a variety of parameters, more detail here.
Are the video tokens signed or encrypted?
The video tokens are signed and are secure. Encryption cannot be implemented on the user-end without causing problems as SignalWire would then need to decrypt them.
Can users be blocked by IP address?
Not at the SignalWire/Token level. You would have to block them from your website/application.
Is the Video API encrypted?
Yes, it is encrypted through HTTPS and SRTP. WebRTC products are required to be encrypted!
Is SignalWire video HIPAA compliant?
Yes! You control access to video conferences via JWT tokens, recording is disabled by default and must be enabled manually, and recordings can be deleted from SignalWire.
Can I incorporate chat?
Yes! When building your website you will have to generate a unique token for the video room and the chat room, but both can exist on the same page.
Can I use video filters?
There is no native support for this at the moment, but you can implement it yourself using video overlays.
Why do users' cameras briefly activate when joining while muted?
SignalWire enumerates over all devices and ‘checks’ the devices where permissions allow. No video/audio data is transmitted during this test.
Does SignalWire support RTMP?
The Video API supports inbound RTMP via the play method, and outbound RTMP via the startStream method.
Where are recordings stored?
Video Room recordings can be found in your SignalWire Dashboard. Click on Video in the left sidebar, then find a list of recordings under the Recordings tab.
How can recordings be downloaded/deleted?
Video room recordings can be deleted or downloaded via your SignalWire Dashboard in the video recordings section or via the API.
What is considered a participant?
Any new member in the room - this could be a person who joined or a screen being shared.
Are Programmable Video Conferences customizable?
Yes! With Programmable Video Conferences, you can now change the background color, foreground color, primary color, success color, negative color, and switch from light mode to dark mode.
Do Programmable Video Conferences have automatic recording?
Yes, you can choose to start recording as soon as the room starts in the settings for Programmable Video Conferences. Even if you do not select this, moderators will still have the ability to manually start and stop recording at their own discretion. Guests will not have this ability.
