I have a problem in Flash with AS3 to playing a video mp4, this is a H.264 video with AAC, I try to play video while it is loading as any web site, but my code doesn't work, I have two codes:
Using FLVPlayback:
var par:Object = LoaderInfo(this.root.loaderInfo).parameters;
//vidRepFla is my FLVPlayback
vidRepFla.addEventListener(VideoEvent.READY,vid_ready);
vidRepFla.addEventListener(VideoProgressEvent.PROGRESS,vid_progress);
vidRepFla.isLive = true;
vidRepFla.bufferTime = 1;
vidRepFla.play(par.source);
function vid_ready(e:VideoEvent):void{
trace('Playing!');
vidRepFla.play();
}
function vid_progress(e:VideoProgressEvent){
trace(e.bytesLoaded);
}
Using NetStream:
var par:Object = LoaderInfo(this.root.loaderInfo).parameters;
var video:Video;
var connect_nc:NetConnection = new NetConnection();
connect_nc.connect(null);
var stream_ns:NetStream = new NetStream(connect_nc);
stream_ns.client = this;
video = new Video();
addChild(video);
stream_ns.bufferTime = 1;
video.attachNetStream(stream_ns);
stream_ns.play(par.source);
Do you know if I need something more or if this type video don't work the bufferTime?
Thanks!
I work with Netstream and use a different method. I did notice something on the Adobe documentation for this. I read that the bufferTime setting Only works on flv files, this could be the problem since you are using mp4.

I have wav files that are at 1411kbs bit rate and varying frequencies. After I import them into the library and give them unique classes based on their frequency and other information (that is why I use getDefinitionByName below).
All of my wav files play fine in AS3 that are under 6000hz and 8000hz, however those tones don't play properly. However, they do play properly when clicking the Play icon when in Flash Adobe Animate.
I have stripped my code down to the bare essentials to see where the problem lies and still not working properly.
My question is, is there a problem with my code or does AS3/Flash have a limit on the frequency it can play?
var mySound:Sound = new Sound();
var myChannel:SoundChannel = new SoundChannel();
btn.addEventListener(MouseEvent.CLICK, function(){
var sound_class = "L6000_0";
var soundTX:SoundTransform = myChannel.soundTransform;
soundTX.leftToLeft = 1;
soundTX.leftToRight = 0;
soundTX.volume = 1;
soundTX.rightToRight = 0;
soundTX.rightToLeft = 0;
var sclass:Class = getDefinitionByName(sound_class) as Class;
var mySound:Sound = new sclass;
myChannel.stop();
myChannel = mySound.play();
myChannel.soundTransform = soundTX;
});
It is not the scripting problem, I think. By default Flash exports sounds at very low bitrate and quality. Go to each sound properties to set the export settings or, alternately, in File > Publish Settings screen there's an option about exporting sounds.
I am working on audio player which play sound of mp4 file format.
This audio file are of recorded files by user, which will play in audio player later.
And another thing is mp4 file url is rtmp not http which is like:
rtmp://domain/vod/mp4:foldername/filname.mp4
I have done following things:
<s:Button id="btnPlay" label="Play" click="Play_clickHandler(event)" />
AS:
public var sound:Sound;
public var mySoundChannel:SoundChannel;
protected function Play_clickHandler(event:MouseEvent):void
{
sound = new Sound();
sound.addEventListener(Event.SOUND_COMPLETE, soundComplete);
var req:URLRequest = new URLRequest("rtmp://domain/vod/mp4:foldername/filname.mp4");
sound.load(req);
mySoundChannel = sound.play();
}
private function soundComplete(event:Event):void {
sound.load(new URLRequest("rtmp://domain/vod/mp4:foldername/filname.mp4"));
mySoundChannel = sound.play();
}
I Have tried above code but didn't succeed. It played only mp3 file format.
Any way i can play this file?
Note: I do not want to convert file to mp3 file format using any method.
I have tried to play this file in VideoPlayer. It works but design looks bad.
FYI:
Audio file format is:
Any help is greatly appreciated.
You can not use a Sound object to play the audio of an RTMP stream like that.
But to do that, I think that the easiest way is to use a NetStream object and with its receiveVideo() function, you can receive just the audio stream, also you don't even need any video player to be attached to it.
Take a look on this example :
var server:String = 'rtmp://localhost/vod',
stream:String = 'mp4:video.mp4',
nc:NetConnection,
ns:NetStream;
function init(): void
{
nc = new NetConnection();
nc.addEventListener(NetStatusEvent.NET_STATUS, on_NetStatus);
nc.connect(server);
}
function on_NetStatus(e:NetStatusEvent): void
{
if(e.info.code == 'NetConnection.Connect.Success'){
ns = new NetStream(nc);
ns.receiveVideo(false);
ns.play(stream);
}
}
init();
Hope that can help.
I'm currently working on a AS3 AIR project which involves allowing the user to browse a video file and load that same video onto the stage. I've managed to allow the user to browse for a video file type and according to my traces it completes loading the video but this is as far as I've got. There is plenty of tutorials which involve how to load video files from local sources or external links but nothing to show me what to do with a browsed file to display it on the stage. Here is the code so far for browsing to the video file:
private function browseVideo():void {
fileReference = new FileReference();
fileReference.addEventListener(Event.SELECT, videoFileSelected);
var videoTypeFilter:FileFilter = new FileFilter("Video files", "*.3g2; *.3gp; *.asf; *.asx; *.avi; *.flv; *.m4v; *.mov; *.mp4; *.mpg; *.rm; *.swf; *.vob; *.wmv;");
fileReference.browse([videoTypeFilter]);
}
private function videoFileSelected(e:Event):void {
fileReference.addEventListener(Event.COMPLETE, onVideoFileLoaded);
fileReference.addEventListener(IOErrorEvent.IO_ERROR, onVideoFileLoadError);
fileReference.load();
}
function onVideoFileLoaded(e:Event):void {
var fileReferenceTarget:FileReference = e.target as FileReference;
var data:ByteArray = fileReferenceTarget["data"];
fileReference.removeEventListener(Event.COMPLETE, onVideoFileLoaded);
fileReference.removeEventListener(IOErrorEvent.IO_ERROR, onVideoFileLoadError);
var videoLoader:Loader = new Loader();
videoLoader.loadBytes(data);
videoLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, onVideoLoaderComplete);
trace("video file loaded");
}
function onVideoFileLoadError(e:Event):void {
fileReference.removeEventListener(Event.COMPLETE, onVideoFileLoaded);
fileReference.removeEventListener(IOErrorEvent.IO_ERROR, onVideoFileLoadError);
trace("video file load failed");
}
function onVideoLoaderComplete(e:Event):void {
var loadedContent:DisplayObject = e.target.content;
var loader:Loader = e.target.loader as Loader;
scope.addChild(loader);
}
To play a video using AS3 ( Flash ) you can use a Video object on which you can attach a NetStream object, you can also use an FLVPlayback component. For flex, take a look on my answer of this question where I put an example of playing a video stream. And in all cases, I think that you don't need a FileReference object because a File is suffisant to get the path of your local file and then play it with any manner you want.
Take a look on this example :
function browseVideo():void {
var file:File = new File();
file.addEventListener(Event.SELECT, videoFileSelected);
file.browse([videoTypeFilter]);
}
function videoFileSelected(e:Event):void {
playVideo(e.currentTarget.nativePath);
}
function playVideo(video_path:String){
// using a Video + NetStream object
var nc:NetConnection = new NetConnection();
nc.connect(null);
var ns:NetStream = new NetStream(nc);
ns.client = this;
var video:Video = new Video();
video.attachNetStream(ns);
addChild(video);
ns.play(video_path);
// using an FLVPlayback component inserted on the Stage
flvplayback.load(video_path);
flvplayback.play();
}
For more details on how to work with video, you can take a look here, you can find all what you need to know about video ( loading videos, supported formats, cue points, ... ).
Hope that can help.
How do I load an .flv (lets call it "library.flv") sitting in my (internal) Flash library into my Netstream?
I can easily load external .flv's with the below, but I need to load the .flv from my library
//Creating the video object
var ADFvideo = new Video(110,180);
videoContainer.addChild(ADFvideo);
ADFvideo.x = 0;
ADFvideo.y = 0;
//Loading the flv into the video object
var ADFnc:NetConnection = new NetConnection();
ADFnc.connect(null);
var ADFns:NetStream = new NetStream(ADFnc);
ADFvideo.attachNetStream(ADFns);
//Handling metaData (it arrives as the video starts playing, so it is the pefect time to fire the first event);
var ADFcustomClient:Object = new Object();
ADFcustomClient.onMetaData = ADFmetaDataHandler;
ADFns.client = ADFcustomClient;
var ADFinfoObj:Object;
function ADFmetaDataHandler(ADFinfo:Object):void
{
//meta stuff
}
ADFns.play("files/external.flv"); /* current way of loading the external .flv */
ADFns.addEventListener(NetStatusEvent.NET_STATUS, statusChanged);
function statusChanged(stats:NetStatusEvent)
{
//event changes
}
I don't think you can use NetStream with an embedded flv video. When you import the video to your library, you will have the option to convert it to a movieclip or to keep it as a simple video that will sit on the timeline. For the later option, you can't create an AS Linkage. It is not recommended for longer clip as you will experience syncronisation issue, playback problem and pre-loading issues.
You could try this adjustment of your posted code as a starting point.. Tested using 3-second video (H.263 / Sorenson) of 1280 width by 720 height with 44100hz 128 MP3 sound and there was no "..experiencing sluggish behaviour" on my side with a crappy testing machine.
When the video ends you need to use your function statusChanged(stats:NetStatusEvent) to handle what happens next (I've edited the code to do constant replays as example)
Anyway this code means the final compiled SWF and FLV exist as one package. So a 200kb FLV will add +200kb to the output SWF size. Just bear in mind especially with large / multiple FLV embeds.
//// Specify embed item and create Class to store such item
[ Embed(source = "yourFileName.flv", mimeType = "application/octet-stream") ]
var bytes_FLV : Class;
//// End embedded item setup
//create bytes for NStream from embedded item
var file_BA:ByteArray = new bytes_FLV();
//Creating the video object
var ADFvideo = new Video(110,180);
videoContainer.addChild(ADFvideo);
ADFvideo.x = 0;
ADFvideo.y = 0;
//Loading the flv into the video object
var ADFnc:NetConnection = new NetConnection();
ADFnc.connect(null);
var ADFns:NetStream = new NetStream(ADFnc);
ADFvideo.attachNetStream(ADFns);
//Handling metaData (it arrives as the video starts playing, so it is the pefect time to fire the first event);
var ADFcustomClient:Object = new Object();
ADFcustomClient.onMetaData = ADFmetaDataHandler;
ADFns.client = ADFcustomClient;
var ADFinfoObj:Object;
function ADFmetaDataHandler(ADFinfo:Object):void
{
//meta stuff
}
///ADFns.play("files/external.flv"); /* current way of loading the external .flv */
//Send file_BA to NStream for playback..
ADFns.play(null);
ADFns.appendBytesAction(NetStreamAppendBytesAction.RESET_BEGIN);
ADFns.appendBytes(file_BA);
ADFns.addEventListener(NetStatusEvent.NET_STATUS, statusChanged);
function statusChanged(stats:NetStatusEvent)
{
//event changes
//trace("NetStream Status : " + stats.info.code);
if (stats.info.code == "NetStream.Buffer.Empty")
{
//Buffer.Empty = video has ended..
ADFns.appendBytesAction(NetStreamAppendBytesAction.RESET_BEGIN);
ADFns.appendBytes(file_BA);
}
}
I was wondering if someone could shed some light on the best method to embed, select and play audio files in an AIR app built for iOS and Android?
I have an app where a user can select a file to play from a list of 10 audio files. These are selected when a slider moves left or right.
I currently would create 10 individual embed snippets and classes
[Embed(source="assets/audio/file1.mp3)]
public static const file1:Class;
[Embed(source="assets/audio/file2.mp3)]
public static const file2:Class;
...
And then in the app initialise each class so I can reference them. Then simply call
file1.play();
Issue is this only plays the sound once where I would like the sound to look until the user selects another sound.
I guess a couple of questions:
1. Is having 10 embed/classes the best way to handle 10 different MP3 files?
2. How would I loop the MP3 seamlessly
Thanks
You stored Array or Vector mp3 files URL which user selected. and playing mp3 filed ended. load next URL from Array, Vector.
var sound:Sound = new Sound();
var soundChannel:SoundChannel;
var currentIndex:int = 0;
var mp3List:Vector.<String> = new Vector.<String>();
//only stored user selected mp3 url
sound.addEventListener(Event.COMPLETE, onMp3LoadComplete);
sound.load(mp3List[currentIndex]);
function onMp3LoadComplete(e:Event):void
{
sound.removeEventListener(Event.COMPLETE, onMp3LoadComplete);
soundChannel = sound.play();
soundChannel.addEventListener(Event.SOUND_COMPLETE, onSoundChannelSoundComplete);
}
function onSoundChannelSoundComplete(e:Event):void
{
e.currentTarget.removeEventListener(Event.SOUND_COMPLETE, onSoundChannelSoundComplete);
currentIndex++;
if(currentIndex==mp3List.length) currentIndex = 0;
sound.load(mp3List[currentIndex]);
soundChannel = sound.play();
sound.addEventListener(Event.COMPLETE, onMp3LoadComplete);
}
