Hi,

assuming that you've access to raw bytes (that would be best if you receive data asynchronously) I think that you could certainly save data into app storage directory (it lies within application data sandbox on iOS) in a way like:

var file:File = File.applicationStorageDirectory.resolvePath("myVideo.mp4");

then open FileStream and write that data as it arrives (or all at once).

Once you have that file created you could:

- load it directly as discussed here:

- load it via thin "html" hosting web page (you would have to create that thin html hosting page for that video file as well):

(both solutions require StageWebView as you noted)

hth,

Excellent! That worked, Thank you.

Here is what i did:

1) Load video:

var urlLoader = new URLLoader();

urlLoader.dataFormat = URLLoaderDataFormat.BINARY;

urlLoader.addEventListener(ProgressEvent.PROGRESS, onStageVideoProgress);

urlLoader.addEventListener(Event.COMPLETE, onStageVideoLoadComplete);

urlLoader.load(new URLRequest("http://pathToMyVideo/myVideo.mov"));

2) Save the video:

var file:File = File.documentsDirectory.resolvePath("myVideo.mov")

var fileStream:FileStream = new FileStream();

fileStream.openAsync(file, FileMode.WRITE);

fileStream.addEventListener(ProgressEvent.PROGRESS, onStageVideoSaveProgress);

fileStream.addEventListener(Event.CLOSE, onStageVideoSaveClose);

fileStream.addEventListener(Event.COMPLETE, onStageVideoSaveComplete);

fileStream.addEventListener(IOErrorEvent.IO_ERROR, onStageVideoSaveError);

fileStream.writeBytes(stageVideoURLLoader.data);

fileStream.close();

3) Load the saved video to stageWebView:

var stageWebView:StageWebView = new StageWebView();

stageWebView.stage = this.stage;

stageWebView.viewPort = new Rectangle(0, 0, 100, 100);

var file:File = File.documentsDirectory.resolvePath("myVideo.mov")

stageWebView.loadURL(file.url);

Simple enough.
