Authentication & Registration
Step
The moment the user opens the app, they can make and receive calls. Twilio Video makes it easy to authenticate and register devices in a couple lines of code.
var videoClient = TVIVideoClient(token: accessToken)
let connectOptions = TVIConnectOptions.init(token: accessToken)

{ (builder) in
    builder.roomName = "my-room"
    builder.localMedia = self.localMedia
}

room = TVIVideoClient.connect(with: connectOptions, delegate: self)
func participant(_ participant: TVIParticipant, addedVideoTrack
    videoTrack: TVIVideoTrack) {
    NSLog("Participant \(participant.identity) added video track")
}

func participant(_ participant: TVIParticipant, removedVideoTrack
    videoTrack: TVIVideoTrack) {
    NSLog("Participant \(participant.identity) removed video track")
}
/* First, we set a Participant Delegate
   when a Participant first connects: */

func room(_ room: TVIRoom, participantDidConnect participant:
    TVIParticipant) {
    print("Participant connected: \(participant.identity!)")
    participant.delegate = self
}

/* In the Participant Delegate, we can respond when the
   Participant adds a Video Track by rendering it on screen: */

func participant(_ participant: TVIParticipant, addedVideoTrack
    videoTrack: TVIVideoTrack) {
    print("Participant \(participant.identity) added video track")
    videoTrack.attach(self.remoteMediaView)
    videoTrack.delegate = self
}

Capabilities

Real-time video infrastructure for web and mobile developers.

  • Cross-device support

    Twilio provides SDKs for iOS, Android, and JavaScript. Each to provide a great development experience on the target platform. These SDKs include everything you need to get started — no struggling to get WebRTC up and running on your target device.

  • Multi-party

    Session management for orchestrating n-way voice and video Rooms in a peer-to-peer mesh topology, across any combination of supported devices.

  • Open standards

    Built on WebRTC and updated frequently to keep in-step with the latest contributions from the WebRTC community, while ensuring reliable cross-platform support and interoperability.

  • Low-latency TURN

    When direct peer-to-peer connections are not possible, Twilio Video automatically provides low-cost TURN media relay. Deployed in 28 data centers across 7 regions, media is relayed in the nearest geography for the lowest possible latency.

  • Resilient

    Built on the same signaling infrastructure which handles billions of minutes of Twilio Voice traffic, the Video service is geographically distributed for redundancy and uptime guarantees.

  • Web-scale session management

    Scale elastically as load increases. Combined with pay-as-you-go pricing, Twilio Video scales gracefully from one endpoint to millions.

Optimized for iOS, Android, and the web

iOS and Android developers
Optimized media stack

Great quality media on mobile devices is hard. Wi-Fi has high levels of jitter and packet loss, and mobile networks have high latency. Twilio SDKs optimize the mobile media stack for both iOS and Android to handle these challenges.

Mobile screen share

Twilio's mobile SDKs make it easy to capture video from any source or view in your application — not just the camera — and share it in a video Room.

JavaScript developers
WebSocket

Twilio SDKs connect to Twilio over WebSocket for signaling. No intermediate server is needed, communications are handled directly from the cloud to the browser.

Event-driven

Twilio SDKs provide JavaScript Promises to allow for better chaining of functions with flatter code and cleaner error handling.

Twilio-powered WebRTC

Adding to the raw potential of WebRTC in a cross-platform environment.

  • Opus, VP8, and H.264

    The WebRTC media stack supports Opus and VP8 codecs by default. Twilio Video adds support for H.264 to take advantage of hardware acceleration on iOS.

  • Mobile media performance

    Compiling WebRTC for mobile platforms is just the start. Twilio constantly invests in improving the end user experience through a variety of optimizations over/above stock WebRTC.
