Re: [Flashcoders] load flv and its metadata without start to play
Hi Jason,
that's true. Of course I could read out all metadata and store it into
an array or xml. It's the usual decision of flashdevelopers to have a
every-situation-solution vs. a best-for-this-project-solution, right?
;)
Thanks,
Matthias

Hi Glen,
i am somewhat satisfied with my current solution, now, but this is a

you could use flvtool2 to get the metadata server-side and store it in a

Re: [Flashcoders] load flv and its metadata without start to play
Hi,
Have a look at these 2 possible things to combine / work-around
getting the meta-data & streaming via PHP. It is a different thing
altogether, but you may be able to parse the FLV's and store the data in
XML or something?

Sure, we talk about flv from file and ns.play(urlToFile).
I changed ns.bufferTime to a higher value, now.
That's everything I changed lately, and waiting for metadata seems to

Matthias,
I have never had any unwanted sound behavior when I use:
ns.play(src);
ns.pause(true);
If you are hearing an audio blip, it's simple to fix by applying a
SoundTransform with the volume set to 0 before you play/pause the NetStream.
var transform:SoundTransform = ns.soundTransform;
transform.volume = 0;
ns.soundTransform = transform;
ns.play(src);
ns.pause(true);
For the sake of this discussion, I'm going to assume we're talking about
progressive downloads as opposed to FLVs streamed from FMS.
You cannot attach a single NetStream to multiple Video instances.
If you fully load an FLV and caching is turned on (never a guarantee,
but likely) then the FLV will load instantly for the next NetStream that
loads it. HOWEVER, if it is not cached and you start a second NetStream
to load the same FLV before it is finished loading, it will load the
entire file again since it's technically not cached according to the
browser.
I disagree that waiting for metadata is "really ugly". How is any
client, Flash or otherwise, supposed to know anything about a file it's
loading before it starts loading it? The only way it could is if you
hard-code it ahead of time because you know what it is.
If you're waiting for Flash to determine it dynamically, it has to
access the file to get the header information (metadata) that describes
the FLV. Because you can play/pause, the metadata can come before you
even addChild() the video to the display stack.
I don't see how any of this could be considered "really ugly" but if you
do end up writing a psychic script that can determine a file's header
data without ever accessing the file, be sure to let us know. ;)
The ByteArray idea might work, I've never tried it, and it would
probably take you anywhere from 5-15 minutes to try it out. I'm not
sure what benefit it would provide you other than guaranteeing that it
would be stored in memory if browser cache was turned off. At best, you
might get a few milliseconds faster start-up loading from a ByteArray vs
from cache.

Hello Steven, yes, I noticed that. I am waiting for ns.bytesLoaded == ns.bytesTotal, and I wait even until metadata are received, as mentioned earlier. I have shut off the unwanted sound behavior now, but don't know, how I did it. pause(false) ist AS2, Steven? AS3/FlexBuilder doesn't allow me to have parameters for ns.pause(). Sure, we talk about flv from file and ns.play(urlToFile). I changed ns.bufferTime to a higher value, now. That's everything I changed lately, and waiting for metadata seems to become faster (can't explain). I know, that it'll take time to load the header/metadata portion of a flv, Steven, but it felt to long. Now, with bigger buffer time (sounds crazy, I know) it is much faster. I'll try the ByteArray idea... Regards, Matthias On Jan 21, 2008 12:07 PM, Steven Sacks <[EMAIL PROTECTED]> wrote: > Glen, > > Unfortunately, I discovered a bug with the code I posted.

Re: [Flashcoders] load flv and its metadata without start to play
Glen, Unfortunately, I discovered a bug with the code I posted. The NetStream.Buffer.Flush does not fire if the NetStream is paused. You have to check to see if the ns.bytesLoaded == ns.bytesTotal in the onProgress. Matthias, I have never had any unwanted sound behavior when I use: ns.play(src); ns.pause(true); If you are hearing an audio blip, it's simple to fix by applying a SoundTransform with the volume set to 0 before you play/pause the NetStream. var transform:SoundTransform = ns.soundTransform; transform.volume = 0; ns.soundTransform = transform; ns.play(src); ns.pause(true); For the sake of this discussion, I'm going to assume we're talking about progressive downloads as opposed to FLVs streamed from FMS. You cannot attach a single NetStream to multiple Video instances. If you fully load an FLV and caching is turned on (never a guarantee, but likely) then the FLV will load instantly for the next NetStream that loads it. HOWEVER, if it is not cached and you start a second NetStream to load the same FLV before it is finished loading, it will load the entire file again since it's technically not cached according to the browser. I disagree that waiting for metadata is "really ugly". How is any client, Flash or otherwise, supposed to know anything about a file it's loading before it starts loading it? The only way it could is if you hard-code it ahead of time because you know what it is. If you're waiting for Flash to determine it dynamically, it has to access the file to get the header information (metadata) that describes the FLV. Because you can play/pause, the metadata can come before you even addChild() the video to the display stack. I don't see how any of this could be considered "really ugly" but if you do end up writing a psychic script that can determine a file's header data without ever accessing the file, be sure to let us know. ;) The ByteArray idea might work, I've never tried it, and it would probably take you anywhere from 5-15 minutes to try it out. I'm not sure what benefit it would provide you other than guaranteeing that it would be stored in memory if browser cache was turned off. At best, you might get a few milliseconds faster start-up loading from a ByteArray vs from cache.

Re: [Flashcoders] load flv and its metadata without start to play
Hi Glen,
thanks, but that's exactly what I do, but it answers not the related questions:
a) what, if I need the video for a second DisplayObject at the same
time on stage, does it load faster, because it was cached?
b) play() and pause() leads to unwanted sound behaviors when the video
consists of sound
c) how to set the video to the real size? I always need to wait for
metadata, which is really ugly. Otherwise the video is set to default
320x480.
Any thoughts?
Is it perhaps possible to load the FLV as ByteArray and later load the
Netstream from this ByteArray, which might be faster and done a second
time, too?

Re: [Flashcoders] load flv and its metadata without start to play
Hi,
Steven Sacks posted this the other day.

"Preloading FLVs is easy peasy.
var progressTimer:Timer = new Timer(10);
progressTimer.addEventListener(TimerEvent.TIMER, updateProgress);
var nc:NetConnection = new NetConnection();
nc.connect(null);
var ns:NetStream = new NetStream(nc);
progressTimer.start();

ns.pause(true);
private function updateProgress($event:TimerEvent):void
{
dispatchEvent(new ProgressEvent(ProgressEvent.PROGRESS, false,
false, ns.bytesLoaded, ns.bytesTotal));

Hello,
I want to use video for character animations and so I want to preload
several videos without to play them while preloading.
How can I do this in AS3? I found only the play("something.flv")
method. Are there any other possibilities?
Also, I am currently waiting for my metadata handler to be called
before I accept a video as loaded, because I need to set its height
and width, which only works using these values.
video.videoWidth and video.videoHeight doesn't work for me all the time.
And because I have more than one charactor of its kind, do I need to
load the flv as often as many characters I have?
Any suggestions?

[Flashcoders] load flv and its metadata without start to play
Hello,
I want to use video for character animations and so I want to preload
several videos without to play them while preloading.
How can I do this in AS3? I found only the play("something.flv")
method. Are there any other possibilities?
Also, I am currently waiting for my metadata handler to be called
before I accept a video as loaded, because I need to set its height
and width, which only works using these values.
video.videoWidth and video.videoHeight doesn't work for me all the time.
And because I have more than one charactor of its kind, do I need to
load the flv as often as many characters I have?
