R – Embedding binary video data in a swf file

actionscript-3airembeddingflashflv

Is it possible to play video from data that has been embedded in a swf at compile time (with the [Embed] metatag)?

The "Import Video->Embed" feature provided by Flash CS3 etc. is not acceptable because it has many severe limitations (including sound synchronization issues, a maximum number of frames, and other caveats)

I'm interested in being able to bundle flv video data in a swf (along with other assets), which will be played by an AIR application.

I don't think it can be done. Anyone disagree?

As long as your video is an FLV, then the answer is yes - you can use NetStream.appendBytes() to play the embedded ByteArray:

public class Main extends MovieClip
{
    [Embed(source="sample.flv", mimeType="application/octet-stream")]
    private var SampleVideo:Class;

    public function Main():void 
    {
        var video:Video = new Video(320, 240);
        addChild(video);

        var netConnection:NetConnection = new NetConnection();
        netConnection.connect(null);
        var netStream:NetStream = new NetStream(netConnection);
        netStream.client = {};
        video.attachNetStream(netStream);

        var byteArray:ByteArray = new SampleVideo();
        netStream.play(null);
        netStream.appendBytes(byteArray);
    }
}

Did you make sure you marked the embedded resource as an "Embedded Resource" for the solution, so that it bundled it in with the compiled code?

Also, switch to WebResource instead of ScriptResource.

Google searches have a lot of tutorials too. Try Understanding ScriptResource and WebResource in ASP.NET

R – Which Is More Efficient, Embeddeing an FLV or Compiling an FLV to a SWF and Loading it Dynamically

I think that having the event trigger every frame as opposed to only triggering actions occasionally accounts for the performance difference. Hopefully you could minimize the amount of code and conditionals that was run through in the event handler.

Here's an idea I haven't tested:

var dispatch:Object = {
  f1:   function () {textBubble.text = "This is Rush Hour 2";},
  f61:  function () {textBubble.text = "";},
  f111: function () {textBubble.text = "This scene has 50 takes; "
                     +"Jackie Chan said \"Square Madison\" each time.";},
  f171: function () {textBubble.text = "";}
};
addEventListener(Event.ENTER_FRAME, function (e:event) {
  if (dispatch["f"+e.target.currentFrame] is Function) {
        dispatch["f"+e.target.currentFrame]();
  }
});

This uses the Object as an Associative Array as described in the live docs.
