2014 Runtimes Positioning

The Adobe® Flash® Platform runtimes, Flash Player and AIR®, together enable

businesses to efficiently deliver rich customer experiences across multiple

digital touch points. With Flash Player and AIR, content can easily and

consistently move between the browser, standalone applications and native

operating systems to reach users on the devices of their choice. Since the

Adobe runtimes share a common codebase, developers can reuse code to

deploy game console quality 2D and 3D games, rich media applications with

premium high definition video and scalable date driven applications though

both AIR and Flash Player.

FFMPEGCLI VIDEO TRANSCODE

FFMPEG

FFmpeg is a complete, cross-platform

solution to record, convert and stream audio

and video. It includes libavcodec - the

leading audio/video codec library.

Adobe AIR can tap into and control

FFMPEG.

Convert video…

Stream files, desktops, webcams…

How to output?

NativeProcessTHE ENDLESS API

AIR 2.0!

Released in 2010

Theme was “disruption”

Supports NativeProcess

Only the extendedDesktop AIR profile

supports the NativeProcess class.

What is NativeProcess?

“The NativeProcess class provides command line integration and general launching

capabilities. The NativeProcess class lets an AIR application execute native processes

on the host operating system. The AIR application can monitor the standard input

(stdin) and standard output (stdout) stream of the process as well as the process's

standard error (stderr) stream.”

Basically, this new API allows your application to communicate with just about any

process running on the host machine. This can be an operating system core process

or software like FFMPEG.

Originally an experiment…

Uses HandBrake CLI

Fairly popular… for a demo.

NativeProcess ExampleFFMPEG AND BATCH

What to Import

flash.desktop.NativeProcess;

flash.desktop.NativeProcessStartupInfo;

flash.events.NativeProcessExitEvent;

flash.events.ProgressEvent;

flash.events.IOErrorEvent;

flash.filesystem.File;

NativeProcess Setup

Create a new File object to run

Create the NativeProcess and add listeners

Create NativeProcessStartupInfo instance

Build up your arguments as Vector

Bind everything together and start

NativeProcess Communication

Standard Input

nativeProcess.standardInput.writeUTF();

Standard Output

nativeProcess.standardOutput.readUTFBytes();

Simple Example – DEMO!!!

FFMPEG is command-line driven

Batch files are useful for CLI

1. Invoke Windows Command Prompt

2. Call a batch file

3. Instruct FFMPEG

4. Read the output

VOD TranscodeFOR FLASH AND HTML5

VideoManager

System for the University of Denver

Faculty, staff, and student uploads

Video is gathered from upload server [AIR]

Video is converted on server [AIR/FFMPEG]

Converted video is moved to AMS

Adobe Media Server streams [HDS/HLS]

CrunchBuddy

Headless AIR app

AIR Captive Runtime

Installed as a Windows service

3 transcode servers host this service:

CRUNCHER, CRUNCHER2, CRUNCHER3

Processes up to 50 videos a day

CrunchBuddy - Process

Listens for files added to a temp directory on

the VideoManager web server.

Pulls those files over the network into a

queue.

Uses MediaInfo libraries to read bitrate,

resolution, rotation, and so forth.

Makes decisions on how to encode the file.

Performs transcode and moves the file(s) to

Adobe Media Server for streaming.

Alerts the user that their file is ready through

VideoManger communication.

Problems? Log file is written.
