netStream..rewind/fast forward an FLV??

[Christam1]

OK well I've made a video player using XML and netstream to bring in the FLV's - but how on earth would I go about making fast forward/rewind buttons to control it? I've browsed forums for ages but can't find a solution..someone please help!

Thankyou for your time!

Hi,

Here's the code to fastforward when using my Custom FLV Player component:

function fastForward (toTime, step)
{
	this.toTime = toTime;
	this.step = step;
	count = 0;
	this.onEnterFrame = function()
	{
		duration = myDisplay._duration;
		// Wait until duration property is accessible, only then can we begin fast forward
		if(myDisplay._duration != null)
		{
			delete this.onEnterFrame;
			this.onEnterFrame = moveForward;
		}
	}
}
function moveForward ()
{
	if(myDisplay._netStream.time >= toTime)
	{
		delete this.onEnterFrame;
		return;
	}
	var currentTime = myDisplay._netStream.time;
	myDisplay._netStream.seek(currentTime + step);

}
// begin fast forward to 20 seconds, stepping forward by 0.1 seconds each frame
fastForward(20, 0.1);

Start the fast-forward by calling the function
fastForward(toTime, step);
where 'toTime' is the time in seconds to fast-forward to, and 'step' is the amount of time in seconds to move forward each frame of the fast-forward. The value of 'step' cannot be lower than 0.1. The higher the value of 'step', the faster the fast-forward.

Your FLV should have plenty of keyframes encoded for the fast-forward effect to work.

how about in AS3?

Is there a way to make ff or rw to f4v ?

[Dene]

My video component above was developed for AS2.

For AS3, coding from scratch would involve calling the seek() function (of the NetStream object) repeatedly while the fast-forward button is held down.

I would do this with a Timer. Each time the TimerEvent runs, increment the time value passed to seek().

Thanks for the code Dene!
I'm trying to get this to work and haven't quite got there yet. What is the "my_display" part? Perhaps that's what's missing in my application.
Best wishes,

In Custom FLV Player's component's, the Display component (which might have an instance name of 'myDisplay') is the video object which displays the video.
