Looping MP4 video with AS3

I am trying to get a simple loaded MP4 video to loop in the background.

The component name is "videoloop"
and the file name is "OTG_MainLoop_1080p.mp4"

Here is the code.

videoloop.source="Content/OTG_MainLoop_1080p.mp4"
videoloop.autoRewind=true
videoloop.addEventListener(VideoEvent.AUTO_REWOUND, videoPlayAgain,
false, 0, true)
function videoPlayAgain( event:VideoEvent):void

event.target.play()



This is the error I get in the console, if it helps any.

TypeError: Error #1034: Type Coercion failed: cannot convert fl.video::VideoEvent@460cf159 to flash.events.VideoEvent.
at flash.events::EventDispatcher/dispatchEventFunction()

Any help would be greatly appreciated.

Thanks

Your error is because AS3 compiler is confusing your FLV Component's own internal videoEvent #1 against the other built-in Video Event #2 which is meant to be used for Video and NetStream based objects.

Video

NetStream

These two types are not compatible so you cannot force (coerce) a type #1 to act like a type #2. ...At least not while using AS3 language.

type #1

type #2

solution:

It works if you listen for the event is "complete" signal:

event is "complete"

videoloop.source="Content/OTG_MainLoop_1080p.mp4";
//videoloop.autoRewind=true; //is not needed.

videoloop.addEventListener("complete", videoPlayAgain, false, 0, true);

function videoPlayAgain (event:Event):void

event.target.seek(0);
event.target.play();



FLV Component is sometimes glitchy with some re-plays (example: after some loops the video freezes, then plays normal after a few seconds). I think it depends on encoder settings when outputting the video file.

You might prefer using the NetStream and Video API to handle video playback.

NetStream

Video

//# setup Video object and related Net Stream/Connection objects
var vidloop:Video = new Video(); addChild(vidloop);
vidloop.width = stage.stageWidth; vidloop.height = stage.stageHeight;

var vidNC:NetConnection = new NetConnection(); vidNC.connect(null);
var vidNS:NetStream = new NetStream(vidNC); vidloop.attachNetStream(vidNS);

//# metadata handler to correctly display video
var metaListener :Object = new Object(); metaListener = onMetaData: process_Metadata ;
vidNS.client = metaListener;

//# play video file
vidNS.addEventListener(NetStatusEvent.NET_STATUS, videoStatusHandler); //checks for ending
vidNS.play("Content/OTG_MainLoop_1080p.mp4");


function videoStatusHandler (event:NetStatusEvent):void

if (event.info.code == "NetStream.Buffer.Empty") //buffer is empty when video ends...

//# ...so rewind and play again.
vidNS.seek(0); vidNS.resume();




function process_Metadata (in_Data :Object):void

//check metadata like width, height, duration etc
//trace("duration is : " + in_Data.duration );
