From the original article(s) found here http://www.techshinobi.com/index.php/actionscript-pycurl-and-socks/ I have rewritten the code a bit to play a video file (flv) on a mobile device from a Tor (Onion Network) Hidden Service.

Here is the actionscript code (and below the web2py/pycurl function), enjoy!

package 
{
	// Media
	import flash.display.Sprite;
	import flash.media.Video;
	
	// Network
	import flash.net.URLLoader;
	import flash.net.URLRequest;
	import flash.net.URLLoaderDataFormat;
	import flash.net.NetConnection;
	import flash.net.NetStream;
	import flash.net.NetStreamAppendBytesAction;

	// Events
	import flash.events.Event;
	import flash.events.NetStatusEvent;
	import flash.events.ProgressEvent;
	import flash.events.IOErrorEvent;
	
	// Data
	 import flash.utils.ByteArray;
	
	// Security
	import flash.system.Security;
	
	public class Main extends Sprite
	{
		// Handle For Desktop/Web/Mobile
		try 
		{
			// Security Policies
			Security.allowDomain('xx.xx.xxx.xxx');
			Security.loadPolicyFile('http://xx.xx.xxx.xxx/strange/static/crossdomain.xml');
		}
		catch (e) 
		{};

		// Proxy URL
		public var proxy:String = "http://xx.xx.xxx.xxx/strange/re_quest?param1=static¶m2=demo.flv";
				
		// Video Playback
		private var netConnection:NetConnection;
		private var netStream:NetStream;
		private var video:Video;
		private var bytes:ByteArray;
	
		public function Main()
		{	
			video = new Video(320, 240);
			netConnection = new NetConnection();
			netConnection.addEventListener(NetStatusEvent.NET_STATUS, netConnectionStatusHandler);
			addChild(video);
			
			var ur:URLRequest = new URLRequest(proxy);
			var ul:URLLoader = new URLLoader();
			ul.dataFormat = URLLoaderDataFormat.BINARY;
			ul.addEventListener(Event.COMPLETE, function(ev:Event):void
			{
				bytes = ul.data;
				netConnection.connect(null);
			});
			ul.load(ur);
		}
		
		public function netConnectionStatusHandler(ev:NetStatusEvent):void
		{
			switch(ev.info.code)
			{
				case 'NetConnection.Connect.Success':
					netStream = new NetStream(netConnection);
					netStream.client = {};
					video.attachNetStream(netStream);
					netStream.play(null);						
					netStream.appendBytes(bytes);
					break;
			}
		} 
	}
}

The code on the web server hosting the Privoxy and Tor client.

import pycurl
from StringIO import StringIO

def re_quest():
    url = "http://eoshdbe77ah552wy.onion/hetodjabdloekio/"
    param1 = str(request.get_vars["param1"])
    param2 = str(request.get_vars["param2"])
    param1 = param1.rstrip()
    param2 = param2.rstrip()
    re_url = url + param1 + "/" + param2
    
    header = StringIO()
    buffer = StringIO()
    c = pycurl.Curl()
    
    c.setopt(c.URL, re_url)
    c.setopt(c.USERAGENT, "Mozilla/5.0 (compatible; MSIE 5.01; Windows NT 5.0)")
    
    c.setopt(c.PROXY, "xx.xx.xxx.xxx")
    c.setopt(c.PROXYPORT, 8118)
    c.setopt(c.PROXYTYPE, c.PROXYTYPE_HTTP)
    c.setopt(c.HTTPPROXYTUNNEL, 1)
    
    c.setopt(c.HEADERFUNCTION, header.write)
    c.setopt(c.WRITEFUNCTION, buffer.write) 
    
    c.perform()
    return buffer.getvalue()
