Adding seek functionality with cue points
(Flash Professional only)
You can embed Navigation cue points in an FLV file to add seeking functionality to your
applications. The
seekToNavCuePoint()
method of the FLVPlayback component locates the
cue point in the FLV file with the specified name, at or after the specified time. You can
specify a name as a string (such as
"part1"
or
"theParty"
).
You can also use the
seekToNextNavCuePoint()
method, which seeks to the next navigation
cue point, based on the current
playheadTime
. You can pass the method a parameter,
time
,
which is the starting time from where to look for the next navigation cue point. The default
value is the current
playheadTime
.
