OSMF + Flex Example

I’ve been checking up on OSMF (Open Source Media Framework) periodically, but found that many of their examples / samples don’t work at the moment (their APIs have been in flux). If you’re just looking for a quick way to get OSMF (v.9) up and running in Flex here’s a bit of code that should help.

< ?xml version="1.0" encoding="utf-8"?>

            private var mediaElement:MediaElement;
            private var mediaPlayer:MediaPlayer;
            private var container:MediaContainer;
            private function init():void
                // set up some listeners for our buttons
                playBtn.addEventListener( MouseEvent.CLICK, playHandler, false, 0, true );
                pauseBtn.addEventListener( MouseEvent.CLICK, pauseHandler, false, 0, true );
                seekBtn.addEventListener( MouseEvent.CLICK, seekHandler, false, 0, true );
                // First create a MediaElement and load some media 
                mediaElement = new VideoElement( new NetLoader, new URLResource( new URL( REMOTE_PROGRESSIVE ) ) );
                // We need a DisplayObject for the video
                container = new MediaContainer(); 
                // feed the display object a media element
                container.addMediaElement( mediaElement ); 
                // Flex requires a DisplayObject to be wrapped in Flex Framework UI Abstraction
                videoParent.addChild( container ); 
                // MediaPlayer is a virtual controller. Assign it a media element and it will autoplay the media by default.
                mediaPlayer = new MediaPlayer( mediaElement );
                // We will manually resize the MediaContainer just for kicks
                LayoutUtils.setAbsoluteLayout( mediaElement.metadata, 640, 360 ); 
            private function playHandler( e:MouseEvent ):void
                if ( !mediaPlayer.playing )

                mediaPlayer.seek( val );

  1. @Charlie – looks like the wordpress code plugin is stripping the last tag. You should be golden if you add a closing application tag and make sure you are linking against the OSMF.swc.

  2. @Brook – Thanks for the help. However there is one issue lingering for a long time. Whenever i try to play a video with OSMF using RTMP i get a security certificate prompt. This happens for each media that i play. Can i disable this ? This problem does not happen with any other player used over the internet.

  3. //mediaElement = new VideoElement( new URLResource( new URL( REMOTE_PROGRESSIVE ) ), new NetLoader );
    mediaElement = new VideoElement( new new StreamingURLResource(“rtmp://fms/app/xxx”), new NetLoader());

  4. hey frnds,
    how can we start video from given time in osmf player and also how to ad cue point to stop it
