WebRTC Low Latency Streaming

Adds WebRTC features into Flowplayer Native

Note: Not a live demo, server configuration is just for example. For live working example try the Millicast Publisher and Subscriber example. Or AWS Kinesis Publisher and Subscriber example.

Example publisher using hidden player managed settings menu. Max device dimensions is disabled using maxDeviceDimensions , the maximum capable dimensions of the device camera will be used which could be 4K which could be too large for publishing. If disabled maxWidth and maxHeight can be used to restrict dimensions if no dimension dropdown is configured.

The WebRTC Subscriber Player is used for subscribing to the stream. If there is a transcoding option enabled in the server a HLS source can be used instead.

If publishing to the server as RTMP using an encoder and restreaming as WebRTC, the subscriber player can be used for subscribing to the stream.

An audio meter display can be used to display microphone activity and volume.

Introduction

The WebRTC is a browser based low latency peering streaming solution with only the requirement of a signal server.

While WebRTC can allow for full 2 way peering, the intended solution is for one to many low latency live broadasting with basic conferencing functions.

With Kurento, Millicast, Ant Media Server and Wowza Media Server conferencing solutions is provided however with Wowza the streams are pulled from the server as WebRTC or HLS. Demo java backend projects are provided.

With Millicast conferencing a demo node websocket service is provided to signal users when a publish stream begins. The WebRTC plugin provides an integrated browser based encoder publishing application, with media device, resolution, codec, bitrate controls. And a subscriber player.

Media device selection can use whatever device the browser detects including video and audio inputs. Audio output control for the publisher is possible for browsers that support it.

Screensharing capabilities with browsers that support it are possible using screen sharing apis. The screen, browser, browser tab can be chosen , with an audio input for audio. This may be suitable for live broadcasting instruction videos or even gaming.

Switching between camera and screenshare video tracks is possible while peering. Retaining the original microphone audio stream. Recording of the media device is possible using browser based media recorder api's for browsers that support it. With a download capability of the recorded data.

Device toggling can turn the video / audio device off before and while publishing.

Supported servers for now is Wowza, Kurento, Millicast WebRTC backends. Wowza only supports one to many peering and no data channels. Provided is a Kurento one to many signal server.

WebRTC settings can be configured as a player overlay,

Volume control of the audio input is made possible using the audio api. This also makes the possibility of an audio meter display

Virtual Meeting Background Removal

With the use of BodyPix and Tensorflow. An included virtual background plugin. Support for dynamic background removal rendering is provided.

This rendering view can be used as the main video stream on the publisher and will be automatically detected.

The auto background uses an AI BodyPix feature that doesn't require a Chromakey Green Screen render. It's not perfect but with fine tuned settings it's enough to make a transparent background to show a background image behind the video.

Background images can be added as a background texture to the video stream.

An interesting and unique feature has been included to switch to screensharing as a background in virtual mode. With a scaled camera video resized in the foreground.

With a screen mode, when switching to screenshare, the camera video will display scaled in the corner

Audio Meter

An audio meter plugin can be configured to display microphone activity and volume. An external container with a peak-meter selector can be setup

<div class="peak-meter absolute right-4 -bottom-1.5 w-auto" style="max-width: 80px; height: 300px;"></div>
