Preload Flash Video

[JacobHaug]

Ok I edited the other file. I specified a buffer time of 15 seconds. You could have set a loader strip if you wanted to but that would have been more work. Here is the URL to the new file.

I will PM you the URL to the edit file.

Hi,

Thanks a lot for your work. I didn't find that I could edit anything in the Flash file though, (I guess I needed to purchase that video player). But I did find a script which I have been trying to use.


var connection_nc:NetConnection = new NetConnection();
connection_nc.connect(null);
var stream_ns:NetStream = new NetStream(connection_nc);


my_video.attachVideo(stream_ns);
stream_ns.setBufferTime(10)
stream_ns.play("Chap1_WMV.flv");

//this.createTextField("loaded_txt", this.getNextHighestDepth(), 200, 10, 160, 22);

var loaded_interval:Number = setInterval(checkBytesLoaded, 500, stream_ns);

function checkBytesLoaded(my_ns:NetStream) {
var pctLoaded:Number = Math.round(my_ns.bytesLoaded / my_ns.bytesTotal * 100);
loaded_txt.text = pctLoaded+"% loaded" ;
_root.progressBar_mc.bar_mc._xscale = pctLoaded;
if (pctLoaded >= 80) {
clearInterval(loaded_interval);
_root.progressBar_mc._alpha = 0;
_root.my_video._x = 0;
loaded_txt.text = "" ;
}
}

We did a thing so we could make the video visible only after it had loaded completely. Problem is although this "preloader" shows the progress of the loading video, and the buffer delays when it starts playing its not actually functioning as a preloader at all, because the preloader is making no difference to when the movie plays.

I am guessing that I can't actually preload the Flash video? Or perhaps there is just a more complicated way to do it.

To reiterate, I don't want the flash video to play until it has loaded, and if I delay it with the buffer, it's not preloading it.

With some of my shorter movies I could just import them actually onto the timeline in Flash and preload with a normal flash preloader but has problems when I had a 5mb flv file.

Thanks

There is a way to pre-load a video, and not allow the video to play until it is loaded. Here are some example solutions...

1. Set the buffer to the length of the video you want to preload, this will stop the video from playing until it has finished. However, I would recommend only buffering a short period (5 seconds) and then playing the video, you could cover the video with a buffering message until the buffer fills.

Here is an example code for solutions number 1...

If you're using an FLVPlayback then just set the buffer length in seconds under the component inspector. If you're using netstream:

Code: Select all

ns.setBufferTime(6); //where '6' is the buffer length in seconds.

The above would only be able to display a buffering MC however, giving the user no idea how far through the download they had come.

Next Solution....

2. Ok next, here is macromedia's solution, to creating a preloader with macromedia flash...

Both solutions will work; I have not used either solution. But the action script seems to be valid, so good luck!! Let me know if I can assist you any further.

Here are some example files i thought you should take a look at. You might be able to use some of the actionscript from the files. Here are the URL's to the two files...
