The FLV file options

The Content Path dialog box also has two options. The first option, Match Source FLV Dimensions, specifies whether the FLVPlayback instance on the Stage should match the dimensions of the source FLV file. The source FLV file contains preferred height and width dimensions for playing. If you select the first option, the dimensions of the FLVPlayback instance are resized to match these preferred dimensions. However, this option is available only if the second option is also checked.

The second option, Download FLV for Cue Points and Dimensions, is enabled only if the content path is an HTTP or RTMP URL, which means the FLV file is not local. Any path that does not end in .flv is also considered a network path because it must be an XML file and could point to FLV files anywhere. This option specifies whether to download or stream a portion of the FLV file to acquire the FLV file dimensions and any cue point definitions that are embedded within it. Flash uses the dimensions to resize the FLVPlayback instance, and it loads the cue point definitions into the cuePoints parameter in the Component inspector. If this option is not selected, the first option is disabled.
