    text
    copied!<p>This is my first question here :D, first sorry about my english.</p> <p>My question is basically how can i save a flash Movie Clip to FLV.</p> <p>The Movie Clip is generated by users and it has various sounds and animations and i need to save an FLV to send it to Youtbue.</p> <p>What have I tried: I found some question here about using an Alchemy Lib that I am using to grab the Movie Clip frame to frame and save it to Bitmap.</p> <p>The Alchemy Lib converts those frames to FLV like a charm and supports saving chunks of sound using ByteArray. </p> <p>In this situation my Problem is, how can i grab the sound of Movie Clip to send it to Alchemy Lib? I´ve tried using:</p> <pre><code>SoundMixer.computeSpectrum(sndData, false, 2); </code></pre> <p>Witch returns me a byteArray in sndData variable but is useless since it´s used for render Audio Wave forms on screen. </p> <p>Thougth aboud using </p> <pre><code>Sound.extract(); </code></pre> <p>but i believe the sound class is used only for one MP3 sound and I need to grab the mixed sounds generated by Movie Clip.</p> <p>Is there another way to generate the FLV from a MovieClip?</p> <p>Below some of my code:</p> <p>I based my code under the tutorial that I found in this link: <a href="http://www.zeropointnine.com/blog/updated-flv-encoder-alchem/" rel="nofollow">http://www.zeropointnine.com/blog/updated-flv-encoder-alchem/</a></p> <pre><code>private const OUTPUT_WIDTH:Number = 550; private const OUTPUT_HEIGHT:Number = 400; private const FLV_FRAMERATE:int = 24; private var _baFlvEncoder:ByteArrayFlvEncoder; public var anime:MovieClip; //Starts recording public function startRecording() { this.addEventListener(Event.ENTER_FRAME, enterFrame); //Initialize the Alchemy Lib _baFlvEncoder = new ByteArrayFlvEncoder(stage.frameRate); _baFlvEncoder.setVideoProperties(OUTPUT_WIDTH, OUTPUT_HEIGHT); _baFlvEncoder.setAudioProperties(FlvEncoder.SAMPLERATE_22KHZ); _baFlvEncoder.start(); } //Stops recording public function stopRecording() { this.removeEventListener(Event.ENTER_FRAME, enterFrame); _baFlvEncoder.updateDurationMetadata(); // Save FLV file via FileReference var fileRef:FileReference = new FileReference(); fileRef.save(_baFlvEncoder.byteArray, "test.flv"); _baFlvEncoder.kill(); } //The Main Loop activated by StartRecording public function enterFrame(evt:Event) { var bmpData:BitmapData = new BitmapData(OUTPUT_WIDTH, OUTPUT_HEIGHT, false, 0xFFFFFFFF); bmpData.draw(anime); var sndData:ByteArray = new ByteArray(); SoundMixer.computeSpectrum(sndData, false, 2); _baFlvEncoder.addFrame(bmpData, sndData); bmpData.dispose(); } </code></pre>
