On-demand content can be streamed over the HTTP Large platform to media players that support either HLS or MPEG-DASH.
This service automatically transmuxRefers to the process of changing the multimedia container while retaining its content (i.e., audio/video).es H.264 encoded live content into a HLS/MPEG-DASH-compatible package.
Step 1: Upload On-Demand Content
Stream on-demand content from either CDN storage or a customer origin.
Verify that the desired H.264 media has been uploaded to either:
This service supports the dynamic streamingAllows a media player to dynamically switch between bit rate streams of varying quality levels, in order to provide an optimal viewing experience based on a client’s bandwidth and CPU usage. of multiple assets of varying quality stored within a single directory.
Step 2: Implement a Media Player
On-demand content may be played back using either a HLS or MPEG-DASH player.
Implement one of the following players:
Basic HLS PlayerFollow these steps to create a web page that streams on-demand content using HLS implemented via HTML5.
- Copy the HLS playback URL corresponding to either CDN storage or a customer origin from the Dynamic Cloud Packaging - VOD page.
- Edit the desired web page to include a video tag.
- Set the "src" attribute to the playback URL copied in step 1.
- Customer Origin Only: Append the name of the desired customer origin to the playback URL.
- Append the path to the directory containing the on-demand content identified earlier in this tutorial (Step 1: Upload On-Demand Content).
Identify the desired asset(s) that will be streamed by appending the following value to the playback URL.
Single asset syntax:
Multiple assets syntax:
- Append the ".m3u8" file extension to the filename defined in the previous step.
Verify that the video tag looks similar to the ones defined below:
<!DOCTYPE html> <html> <head> <title>Dynamic Cloud Packaging - On-Demand Streaming Example (HLS)</title> </head> <body> <p>Content may be streamed from CDN storage: </p> <video src="http://wpc.0001.{Base Domain}/040001/videos/presentation1.mp4.m3u8" height="300" width="400"> </video> <p>Or, it may be streamed from a customer origin: </p> <video src="http://wpc.0001.{Base Domain}/840001/myorigin/videos/presentation1.mp4.m3u8" height="300" width="400"> </video> </body> </html>Basic MPEG-DASH PlayerFollow these steps to create a web page that leverages dash.js to stream on-demand content.
Upload the desired version of DASH player code (e.g., dash.all.js) to CDN storage or a customer origin.
This tutorial assumes that version 1.5.1 of dash.all.js resides in the same directory as the web page created in this tutorial.
Create a web page using the following code:
<!DOCTYPE html> <html> <head> <head> <title>Dynamic Cloud Packaging - Live Streaming Example (MPEG-DASH)</title> <script src="dash.all.js" type="text/javascript"></script> <script> function init() { var video = document.querySelector("#video1"); var context = new Dash.di.DashContext(); var player1 = new MediaPlayer(context); var playbackurl = "<Playback-URL>"; player1.startup(); player1.attachView(video); player1.setAutoPlay(true); player1.attachSource(playbackurl); } </script> <style> video { width: 640px; height: 360px; } </style> </head> <body onload="init()"> <video id="video1" controls="true"></video> </body> </html>- Copy the MPEG-DASH playback URL corresponding to either CDN storage or a customer origin from the Dynamic Cloud Packaging - VOD page.
- Set the playbackurl variable to the playback URL copied in the previous step.
- Customer Origin Only: Append a forward slash and the name of the desired customer origin to the playback URL (e.g., /myorigin).
- Append a forward slash and the path to the directory containing the on-demand content identified earlier in this tutorial (Step 1: Upload On-Demand Content).
Identify the desired asset(s) that will be streamed by appending a forward slash and the following value to the playback URL.
Single asset syntax:
Multiple assets syntax:
- Append the ".mpd" file extension to the filename defined in the previous step.
Verify that the line that sets the playbackurl variable looks similar to this code excerpt:
var playbackurl = "http://wpc.0001.{Base Domain}/040001/videos/presentation1.mp4.mpd";
Upload the above web page to CDN storage or a customer origin server.
Stream the on-demand content identified in step 1 by loading the web page.
