Video in Flex, Flash, and Aftermix

Not covering FLV creation, encoding, or code

Find Dave Hassoun’s speech for the above

Progressive vs Streaming

Progressive: HTTP downloadStream: RTMP stream

VideoDisplay vs NetConnection vs Other Solutions

Most of the time VideoDisplay works.

Watch out for fast context switching, size, and streaming.

Content Distribution Network (CDN)

Most simply, a lot of servers around the world.

Limelight, Akamai are examples.

…Or Use a Video Service Provider

Many choices for dealing with video player, CDN, etc.

Keyframes

(Keyframes in video, not Flash Authoring.)

Keyframes is one part of video compression.

Keyframes from ActionScript

No standard API

Often accessed through metadata

Not usually needed
