Beginning with FLV version 1.1, Macromedia
has added a metadata section into a
FLV file. The metadata contains the
duration of the FLV, among other things.
We can use the duration information
to check whether a movie has reached
the end of playback. Note that not
all FLV files have metadata (you will
need to use software that supports
metadata to create the FLV).
We can retrieve the duration information
by using the following code (frame
1 of the main timeline of the sample
If the FLV has metadata, the code
snippet above will show the duration
of the FLV. You can use the Flix Pro
4 FLV to SWF Converter to check for
the presence of metadata – if
the FLV has no metadata, Flix will
show: “[Flv has no metadata]”.
If your FLV does not have metadata
information, it is recommended that
you re-encode the FLV with programs
that supports metadata, such as Flix
Pro or the Flix Exporter.
Checking for the end of the playback
using metadata is quite straightforward.
Just add a loop to check if the current
playback time is equal to or greater
than the duration. You can view the
implementation of this method by examining
the code on the frame 2 and 3 of the
main timeline of the sample movie.
