OCast: open source cast solution

OCast can help various profiles of multimedia services developers:

As a mobile apps editor, you enable your users to enjoy multimedia content (video, music, etc.) they can watch on large TV screens and control from your apps, via their handsets.

As a multiplay telco, you can boost your TV offers with your own receiver and app(s).

As a hardware manufacturer of TV sets, set-top-boxes, keys, dongles or gaming consoles, you can offer your software partners or internal business units a total control over multimedia cast.

Why should you prefer OCast?

OCast is a comprehensive solution, based on standard protocols:

• Totally free and open-source, with all SDKs published under the Apache 2.0 license,

• Clear and easy to integrate, with self-service documentation and sample codes.

Flexible, with html5 webapps on receiver side and SDKs for senders on iOS & Android,

Secure, as you can filter apps that can control the receiver,

Ready to try, with a receiver software emulator, published as NodeJS sources.

What does OCast do?

OCast lets mobile phone users control – via native sender apps – the multimedia webapps they watch on their TV sets – via hardware receiver dongles, sticks, set-top-boxes, consoles, etc.

OCast is not about mirroring screens but controlling the overall multimedia experience (including audio and video streaming) using the sender as a remote for the receiver, seamlessly and securely.

How does OCast work?

OCast takes care of all low-level communication mechanisms between senders and receivers, including the discovery (based on Dial standard), two-way communication (over websockets), security (white-list based filtering), etc.

OCast helps developers focus on high-level messaging integration in their apps

The sender mobile apps just need to integrate the relevant SDKs:

OCast-iOS SDK (Swift & Obj-C) for iOS devices

OCast-JVM SDK for Android or Java devices.

The hardware receiver just needs to run HTML 5 webapps on a server,
with OCast-JS SDK installed.

Development tools

The receiver emulator OCast-Dongletv-Simulator can be installed on any Linux-based machine: Mac, PC or Raspberry PI 3 (model B).

Two HTML 5 webapps OCast-Samples can be used to test your stream with the Standard-HTML5-Receiver or with the MSE-HTML5-Receiver (dash.js embedded).

The desktop NodeJS sender OCast-Controller can be installed on any Linux-based machine: Mac, PC or Raspberry PI 3 (model B) in order to control the emulator and send commands to a sample webapp.

The mobile demo sender application OCast-Demo-iOS or OCast-Demo-Android can be found in the respective project target. They can be used to test the corresponding OCast SDK on a mobile platform in order to control the emulator and send commands to a sample webapp.

First Approach

The starting point would be to install the emulator and launch it.

The second point would be to launch one of the sender applications.

By selecting the emulator as a target in the sender, a chrome instance will be started by the emulator.

Then the standard HTML 5 webapps will be loaded from the github pages, and can be controlled to play an MP4 stream.
