Crocodile's SDK Adds WebRTC to Your Website or App


At the November 2013 WebRTC Conference & Expo, Crocodile's technical director Peter Dunkley hosted a Crocodile Scrum demo and a presentation entitled, "Conferencing Is a Feature Not a Service."

Dunkley's argument is that WebRTC can add context to media sessions, so conferencing no longer has to be an end in itself. With WebRTC, conferencing becomes a website or app feature and not a separate service.

Crocodile offers a JavaScript SDK for WebRTC and a cloud-based network to support the SDK. The network utilizes signaling servers, media gateways and conferencing servers. Crocodile offers a number of business models, including a fully hosted Platform-as-a-Service (PaaS) that can send trunks into an existing infrastructure or create a private network.

Crocodile's SDK has recently been enhanced to support ad-hoc n-party conferences. Crocodile added functionality to its existing API that allows a user to invite multiple parties to a conference without requiring additional bandwidth per caller.

A two-party Crocodile session is peer-to-peer. However, using peer-to-peer on a three-party conference call doubles the bandwidth requirement per person. As soon as other parties join a Crocodile-enabled conference, Crocodile's SDK transfers the call into a media mixer.

Switching to a media mixer combines all of the audio and video tracks from every participant into a single track, which minimizes bandwidth usage. Crocodile's network allocated bandwidth and takes care of inviting other participants. By adding Crocodile code into an existing website or app, conferencing becomes part of the website or app and not a separate application.

Crocodile's WebRTC application, Crocodile Talk, currently supports conferencing for Google Chrome users. Users open a free account and then purchase credits via PayPal to make mobile and international calls. Additional features include presence, instant messaging and free calls to other Crocodile users.
