Usage

my_FLVplybk.bitrate

Description

Property; a number that specifies the bits per second at which to transfer the FLV file.

When doing a progressive download, you can use the SMIL format, but you must set the bit

rate because there is no automatic detection.

When streaming video from a FCS, you can provide a SMIL file that describes how to switch

between multiple streams based on bandwidth. Bandwidth is automatically detected by FCS,

and, in this case,

bitrate is ignored, if it is set.

For more information on using a SMIL file, see “Using a SMIL file” on page 712.

Example

The following example checks two radio buttons to determine what bit rate to use when

selecting an FLV file from the specified SMIL file. The relevant

video tags in the SMIL file

are shown in the following code:

</switch>

For a low-speed connection, the code sets the bitrate property to force selection of the

appropriate FLV file. For higher speed connections, it takes advantage of automatic

bandwidth detection for streaming from FCS and does not set the bit rate.
