[flexcoders] Re: Security sandbox violation on Bitmapdata.draw( rtmpVid ) despite crosspolicy
I am testing the video player Flex app over 'file:///C:/' but the
Flash CS4 demo is technically on 'file:///C:/' as well. Both are in
subdirectories of my desktop/document folder and both are trying to
access the very same file over RTMP. Here's the official error from
the video player:
-
Security sandbox violation: BitmapData.draw: file:///C:/.../bin-
debug/BaseFLVPlayer.swf cannot access rtmp://.../vod/. No policy
files granted access. at flash.display::BitmapData/draw()
-
I think I'm going test the video player SWF online instead of on my
desktop. I don't think it will help but I've got no other ideas at
this point.

Take a look at this video player; notice there is an image on screen
before the video begins playback:

I'm trying to create similar 'preview frame' functionality in my own
custom-built Flex/AS3-based RTMP video player... I need my the
player
to seek ahead to a given point in video, grab a snapshot for display
as a preview frame, then seek back to the beginning before the user
initiates playback... Or something like that.
I've already got demo code (AS2) for taking a snapshot of a video
after it has started playing. The problem is when I try to write
code
to do the same thing in my AS3 player, I get sandbox violation error
as if I were running the demo SWF and my video player SWF on
different
servers. Both SWFs are in document folders on my computer... The
RTMP host and I have confirmed that the permissions for using
'BitmapData.draw( obj )' on a video stream are in place (the demo
works) so I've got no idea why I'm getting the sandbox violation
error.
Can anyone help me to get a snapshot of a video stream and then
return
the stream to the beginning before the user initiates playback? I've
included the FLA for the demo in Flash CS4 and CS3 format:
http://www.futurewebstudios.com/bitMapViewer2.zip
The demo code is attached separately:
---
import flash.display.BitmapData;
var nc:NetConnection = new NetConnection();
var ns:NetStream;
var myBitmapData:BitmapData = new BitmapData( 160, 120, false,
0x00CC );
var mc_1:MovieClip = this.createEmptyMovieClip( mc,
this.getNextHighestDepth() );
btnCap.addEventListener( click, captureVid );
nc.connect( rtmp://okojcizj1r.rtmphost.com/vod );
//nc.connect( rtmp://localhost/vod );
nc.onStatus = function( p_o )
{
var code = p_o.code;
trace( code );
if ( code == NetConnection.Connect.Success )
{
playLive();
}
};
function playLive()
{
trace( playLive );
mc_1._x = 195;
mc_1._y = 15;
ns = new NetStream( nc );
myVideo.attachVideo( ns );
myVideo.attachAudio( ns );
ns.play( kaye_400 );
ns.onStatus = function( p_o )
{
trace( p_o.code );
};
mc_1.attachBitmap( myBitmapData,this.getNextHighestDepth() );
}
function captureVid()
{
trace( captureVid );
myBitmapData.draw( myVideo );
}

I've also attached a piece of the code in my video player app so you
can see what I'm trying to do; if you need to see more of the code,
let me know and I'll send it to you:
---
public function getScreenCaptureData( seekTime:Number,
vidWidth:Number, vidHeight:Number ):Bitmap
{
var startAt:Number = _netStream.time;
trace( this + getScreenCaptureData -- startAt: + startAt
+ , seekTime: + seekTime + , vidWidth: + vidWidth + ,
vidHeight: + vidHeight );
_netStream.seek( seekTime );
var tempVid:Video = new Video( vidWidth, vidHeight );
tempVid.attachNetStream( _netStream );
var bd:BitmapData = new BitmapData( vidWidth, vidHeight );
bd.draw( tempVid );
_netStream.seek( startAt );
//to be continued...
return new Bitmap();

I tested the video player SWF online... Just as I thought; it didn't
make a difference.
I need to figure out how the Flash CS4/AS2 demo is able to
successfully get a snapshot and why the Flex/AS3 video player is not.

RE: [flexcoders] Re: Security sandbox violation on Bitmapdata.draw( rtmpVid ) despite crosspolicy
Did you try AS3 with CS4? There might be tighter security in AS3. Also check
the code that does the load. You might need to set some security options in AS3
