fixing flex VideoDisplay CuePointManager

I was cre­at­ing a Flex appli­ca­tion to show slides and a pre­sen­ta­tion video of pre­vi­ously recorded pre­sen­ta­tions. Accord­ingly, each slide should appear at a cer­tain point of time in the video — calls for cue points!

As all slides and there appear­ance are stored in a text file in my case, I started adding cue points with Action­Script. But as soon as the video can be con­trolled with a slider, allow­ing to shift for– and back­wards, the event han­dler “cue­Point” was not trig­gered any more. Thus, the slides where not changed cor­rectly as the user jumps ahead, as the cue points between the pre­vi­ous and the new posi­tion did not cause and cue point event.

Finally I wrote AdvCue­Point­Man­ager, inher­it­ing from Cue­Point­Man­ager, but which can deal with jump­ing back– and forward.

Copy it to “<your source folder>/net/svenbuschbeck/flex/video” and use it as follows:

<mx:VideoDisplay cuePointManagerClass="net.svenbuschbeck.flex.video.AdvCuePointManager" />
