Customers who do not want the hassle and expense of buying and
maintaining server hardware and Flash Communication Server software can
get all the benefits of streaming Flash video and MP3 files with the Flash
Video Streaming Service. This service is a load-balanced, redundant
deployment of Flash Communication Server over a reliable Content Delivery
Network.
Figure 5: A simple wizard walks you through publishing FLV files for streaming using
the Flash Video Streaming Service.
Table 2 provides a comparison of these three Flash Video delivery
techniques.

Embedded Video Progressive FLV Streaming FLV
Encoding Video and audio is
encoded on import into
Flash using the Sorenson
Spark codec. Alternately,
FLV files (encoded
elsewhere) can be
imported and placed on the
Flash Timeline (re-
encoding is not necessary).
FLV files are encoded
during export from various
professional editing and
encoding applications.
Requires Flash Video
Exporter, which is available
only with Flash MX
Professional 2004. FLV
files can also be created by
exporting the files from the
Flash Timeline.
Same as Progressive FLV.
In addition, bandwidth
detection capabilities in
streaming enable you to
detect client connection
and feed the appropriately
encoded video. You can
capture live video feeds
from client-side webcams
or DV cameras and control
live encoding variables
such as bitrate, fps, and
video playback size
