Flash Player 6.

Flash Media Server (not required).
The Video class lets you display live or recorded streaming video on the Stage without
embedding it in your SWF file. The video may be a live video stream being captured with the
Camera.get()
command, or a live or recorded video stream or MP3 audio stream being
displayed through the use of a
NetStream.play()
command (which requires Flash Media
Server).
Flash Player 7 supports Flash Video (FLV) encoded with the Sorenson Spark video codec.
Flash Player 8 supports Flash Video (FLV) encoded with either the Sorenson or the On2 VP6
codec and also supports an alpha channel. The On2 VP6 video codec uses less bandwidth
than older technologies, and offers additional deblocking and deringing filters.
If your Flash content dynamically loads Flash Video (using either progressive download or
Flash Media Server), you can use On2 VP6 video without having to republish your SWF for
Flash Player 8, as long as users view your content through Flash Player 8. Only Flash Player 8
supports both publish and playback of On2 VP6 video. By streaming or downloading On2
VP6 video into Flash SWF version 6 or 7, and playing the content using Flash Player 8, you
avoid having to recreate your SWF files for use with Flash Player 8.

In Flash Player 7 and later, Flash Video (FLV) files can be played without the use of
Flash Media Server. In Flash Player 8, you can use the On2 VP6 codec and an alpha
channel. For more information, see the Video class entry in
