Systems and methods for broadcasting live media streams

A network-based system for live media broadcasting, comprising:

• a server system including processing structure configured to:
• deploy processor-executable program code executable on a requesting client computing device for provisioning the requesting client computing device with a browser-based mixing user interface and mixer for selective mixing by rendering content within a respective subregion of an HTML canvas of the browser of the requesting client computing device using at least one media stream received by the requesting client computing device to generate a mixed video stream using the content rendered within the HTML canvas and at least one associated audio stream;
• the processing structure further configured to:
• receive one or more live media streams from other client computing devices;
• stream media data from the one or more live media streams to the requesting client computing device over at least one live streaming media connection;
• and
• receive, from the requesting client computing device, the mixed video stream and the at least one associated audio stream;
• wherein the processor-executable program code executable on a requesting client computing device is further for provisioning the requesting client computing device to regulate a rendering rate of the HTML canvas using an audio oscillator node.

A non-transitory computer readable medium embodying a computer program executable on a server system for live media broadcasting, the computer program comprising:

• computer program code for deploying processor-executable program code executable on a requesting client computing device for provisioning the requesting client computing device with a browser-based mixing user interface and mixer for selective mixing by rendering content within a respective subregion of an HTML canvas of the browser of the requesting client computing device using at least one media stream received by the requesting client computing device to generate a mixed video stream using the content rendered within the HTML canvas and at least one associated audio stream;
• computer program code for receiving one or more live media streams from other client computing devices;
• computer program code for streaming media data from the one or more live media streams to the requesting client computing device over at least one live streaming media connection;
• and
• computer program code for receiving, from the requesting client computing device, the mixed video stream and the at least one associated audio stream,
• wherein the processor-executable program code executable on a requesting client computing device is further for provisioning the requesting client computing device to regulate a rendering rate of the HTML canvas using an audio oscillator node.

• computer program code for receiving, from the requesting client computing device, the mixed video stream and the at least one associated audio stream;
• and
• wherein the received one or more live media streams comprises at least one live non-WebRTC media stream;
• wherein the computer program further comprises computer program code for:
• transcoding the at least one live non-WebRTC media stream to generate a WebRTC-compatible media stream;
• publishing the WebRTC-compatible media stream to a WebRTC gateway of the server system using Real Time Streaming Protocol (RTSP);
• and
• using the WebRTC gateway of the server system, streaming the WebRTC-compatible media stream to the requesting client computing device over a respective WebRTC connection for selectively mixing using the requesting client computing device.
