The following example shows how you can display a FLV file in a Flex application using the NetConnection, NetStream, and Video classes, as well as how to use the onMetaData and onCuePoint event handlers to handle video meta data and cue points.

Good job!
Niceeeee!!!
great
This is a very good and simple example! I really do find your blog incredibly useful.
I’m pretty new to flex and am checking out the video features. I’m seeing everywhere examples (yours being the simplest) on streaming .flv files but hardly any on doing the same for H.264 files. I tried it in this example with its location on my fms and it did not work. Is there anything else I need to add?
Also, I was wondering if there was any specific reason you put the video in UIComponent instead of just a videoDisplay component?
Thanks!
Hey, Nice blog. Slamice is right. Even I wanted to know whether it is possible to play H.264 contents on flex.
thanks..
Shiv: VideoDisplay extends UIComponent, and contains an instance of Video object so you wouldn’t place a Video object inside a VideoDisplay because it would be redundant. The reason it’s added to a UIComponent is because UIComponent is the very top component of Flex. All Flex containers (i.e. Canvas, Panel, HBox, etc) require their children to be a UIComponent as well. Video does not extend from UIComponent, so by itself, it’s not a Flex component. It’s originally a flash component so you have to add it to a UIComponent before adding it to any Flex Component.
If you are doing simple playback of video VideoDisplay a really easy way to playback simple video. If you are doing something more exotic then Video, NetConnection, NetStream, etc are going to give you more control but they are much harder to use.
Can we do the same thing with a XML playlist ? if yes how do we do it ?
Hello, I do not have a lot of experience with Flex and am completely new at using video in any way. I am basing a Flex custom omponent on the above code, but am working with a video that is 23x the size of the sample here.
I am thinking of some kind of progress bar before the buttons, screen, etc. are visible. I would appreciate any ideas on how to accomplish this.
Best regards,

Hi,
Just wondering if I can play two netstreams in one netconnection simultaneously.
When I tried that, both videos can’t play well. Please advise.
Thanks.

Please provide a html java script version as well of this example if possible thank you.
Is it me or this code should not work:
in init() the following call is made:
nsClient.onMetaData = ns_onMetaData;
whereas as method ns_onMetaData should take an input Object:
private function ns_onMetaData(item:Object):void {…}
And, furthermore, ns_onMetaData() returns void, but in init() it is supposed to assign a value to nsClient.onMetaData.
Am I not understanding basic AS syntax or what?
Thanks a lot
Hi Everyone,
Can any one help me to convert any type of Video files into .flv format (i.e) flash video format.
I mean, if we browse and select any type of video, it (Flex Program) should convert it to .flv format.
Thanks in Advance……
The example was very helpful.
I have found that the NetStream really shouldn’t be opened until you are sure you have a good NetConnection.
_nc.addEventListener(NetStatusEvent.NET_STATUS, onConnectStatusEvent, false);
Also, to the previous poster… vlc works very nicely.

Hi,
Very nice blog. I have a problem i want a live video streaming but i m unable to do this. While my code is working properly on local system but when i have upoaded on server it is not creating any file. I think u will solve my problem. I have mentoned my fms path:

quick question, can i send a camera using netstream?
Thanks for this.
I’ve been moving a lot of my actionscript 2.0 mush into nice, clean actionscript 3.0 and this has helped alot.
Keep on coding! :)
Hi:
The example was very helpful. I am learning Flex/AS3 and have created a simple Player to play H264 video. I am using var videoFrame:VideoDisplay; in the player. When I set the videoFrame.source property to something like http://myserver.com/test.mp4 all is well. When I try to use a URL like http://myserver.com/getvideo.php?id=12345 (which returns a valid mp4 file with correct http headers etc.) I do not see the video play. I currently use the QT plugin in a web page with URLs like the one above and it works fine.
If I use an approach like your example with the NetConnection and NetStream objects should the flash player be able to load and play video content that comes from a server script instead of directly from a video file in the servers document root?
Thanks for any advice.
Mark
PS - My SWF file and all the video content and PHP script are in the same location on the server so my assumption is that this not a security issue.
