How to Live Stream to Any Device from a Single Encoder Stream

At the recent 流媒体 East conference in New York City, 克里斯•诺尔顿, vice president of product management for Wowza, explained how to successfully send a live stream from a remote location, a stream that viewers and customers can see no matter what device they're using.

"The major question that the session hopes to answer is, if you have so many different formats and streaming protocols and devices out there, and you want to hit as many of those as possible in order to address the widest number of users, how best can you do that with the least amount of infrastructure and the least amount of expense?诺尔顿说.

While Knowlton admitted to a bias to Wowza products (not surprising), he gave instructions that apply no matter the server being used. He began with a diagram of a simple workflow and built from there.

"The basic workflow for anything you're going to be doing is going to be the basic I have a camera for a live stream, I'm going to encode it, push it into a server -- in our case it'll just be a single-origin server, a media server -- and then push that to various clients. So, I'll build on this when we get into the multiformat workflow in a few minutes, but that's just the basic premise," explained Knowlton. "It could be a file for those of you who aren't doing live or who are recording something now and then playing it back later."

HOW-TO: Adaptive 在线直播 to Any Device From a Single Encoder Stream

With so many devices and streaming formats, how do you get your audio and video content to your customers? The task becomes even more challenging if you are streaming from a remote location with limited uplink bandwidth. This session shows you how to take a single stream from an encoder and use tools to convert it on-the-fly into dynamic adaptive bitrate streaming for delivery to nearly any screen or device. For live streaming, we also demonstrate how to enable DVR controls (pause, 向前, 倒带, resume to live) and DRM.
