Thank any way for this great code !!!

So you are saying SEEK is accurate to thousand’s of a second (to the extent that the keyframes are there)??

Yes, to the extent that a keyframe is present, you have approximately millisecond accuracy. Keep in mind that most video is encoded at NTSC and PAL framerates or slower — which aren’t anywhere near 1,000fps (not by a long shot!) … but at least you can specify a seek to the nearest millisecond. Might be very hard to demonstrate practically, though.

A hint in support of my assertion is that the NetStream.seek() method in AS3 accepts a Number datatype (floating point) rather than, say, int (integer). If that sort of accuracy is really important, though, your best bet is very like a streaming server, which allows you to seek to any video frame (not just keyframes).

“For progressive download, the video seek to the first keyframe encountered after the specified time (use up to three decimal places to indicate times less than a second).”

As Okeedoodle says “But everything I’ve found so far controls flv videos by seconds rather than milliseconds” — this is the impression I got too (when talking about progressive downloads). If it’s true that seek can be used to something like frame accuracy, as opposed to whole second accuracy, that will be great! I hope you are right!

The onMetaData event requires Flash Player 7 or higher — could that be it?

**Error** Scene=Scene 1, layer=actions, frame=1:Line 11: There is no property with the name ‘onMetaData’.
ns.onMetaData = function(evt:Object):Void {

any ideas? Thanks so much

There are two ways to go. If you’re streaming your video via Flash Media Server, Red5, or the like, you can seek to any video frame, which may or may not fall on a given millisecond (depends entirely on the framerate of the movie, and I’ve never seen a 1000fps video framerate — not even sure that’s possible). If you’re progressively downloading, as shown in the code sample in the article, then you can only seek to video keyframes, and not only that, but keyframes that have already been loaded. You can still get millisecond-specific, but the chances would be even worse that a video keyframe would fall exactly along a given millisecond. For progressive download, the video seek to the first keyframe encountered after the specified time (use up to three decimal places to indicate times less than a second).

Honestly, I haven’t dipped into those FLVPlayback-related source files much. FLVPlayback is a bit different from the other components, but they’re all pretty complex beasts. The code you’re after isn’t going to be in the FLAs, though. It’s going to be in ActionScript files (class files). In my Win XP machine, those files are located …

C:\Program Files\Adobe\Adobe Flash CS3\en\First Run\
Classes\mx\video\

It really might be easier to start from scratch!

I tried:

played._x = knob._x;

…”played” is a movie clip that darkens the seek bar with the registration point of on the right. It places the “played” clip where the knob starts but doesn’t follow it as it moves.

In order for the played movie clip to follow the knob movie clip, you’ll have to repeatedly update played’s position. The single line of code you showed will set those _x properties to the same value at that moment. To repeat the process, you’ll have to put that line inside the loop that continuously moves knob (in the blog article that happens inside a setInterval() loop).

Another thing I’ve been toying with ( in my pursuit of creating a video player like YouTube ) is in the seek bar where the left side of the scrub handle is lighter than the right side.
