Streaming to YouTube Live? Put an API on it!
2013年5月2日星期四
The
YouTube Live Streaming API
makes it easier to build tools and apps for channels that are enabled to stream live content on YouTube. With the YouTube Live platform, you have the ability to real-time transcode to a range of video qualities that support a broad set of devices and networks, dynamic bandwidth adjustment so viewers automatically see the highest quality stream their network supports, and DVR-like controls to allow viewers to pause, fast forward, and rewind during a live stream.
How to start developing with live streams
The basics
A
broadcast
represents a live event that you'll stream on YouTube. The API lets you schedule a broadcast, bind it to your live video stream, and update its status to
testing
,
live
, or
complete
.
A
stream
represents the actual broadcast content.
A
cuepoint
represents an ad break that can be inserted into a live broadcast. Cuepoints are only available to YouTube content partners.
Documentation
The
Getting Started
guide explains these concepts in more detail and explains how they interact with other YouTube Data API and YouTube Content ID API resources.
The
Life of a Broadcast
guide
walks you through the typical steps for creating and managing a live broadcast on YouTube.
The
YouTube Live Streaming Guide
identifies the encoder settings, bitrates, and resolutions that the YouTube Live Streaming platform supports.
Samp
le code and tools
Client libraries
for many different programming languages can help you implement the YouTube Live Streaming API as well as many other Google APIs.
Don't write code from scratch! Our
Java
,
PHP
, and
Python
code
samples
will help you get started.
The
APIs Explorer
lets you try out sample calls before writing any code.
In addition, in this video, we talk about the philosophy we followed in building the API and also see some great demos from our partners.
Awesome examples
Here are a few great examples from developers already using the API:
Capella’s Cambria Live
Capella
’s Cambria Live encodes live broadcasts in real time and streams them to YouTube Live. Cambria Live takes uncompressed broadcast video directly from a camera via SDI or HDMI and compresses it into the H.264 format with AAC audio, ensuring optimal video and audio quality.
Elgato
Elgato
Game Capture HD enables you to stream PlayStation or Xbox gameplay to share it with your friends and fans as it happens. Elgato’s video products enable high-quality video recording and conversion for consumers and professionals alike.
XSplit
Radioline
XSplit
is a streaming and video-mixing application that is fun and easy to use. It is widely-used for streaming games.
Radioline
designs and operates a cloud-based mobile internet radio. You can find or discover new radio stations according to their names, genres, areas or according to your favorite playlists.
This API is still
experimental
, so stay tuned here and subscribe to the
YouTube for Developers
channel to keep up on the latest.
