Please help me fill the question marks. I want to get a feed from my camera and to pass it to the receive function. Also in flash builder(in design mode) how do I put elements so they can play a camera feed?? Because as it seems VideoDisplay just doesn't work
public function receive(???:???):void{
//othercam is a graphic element(VideoDisplay)
othercam.??? = ????;
}
private function send():void{
var mycam:Camera = Camera.getCamera();
//mycam2.attachCamera(mycam);
//sendstr is a stream we send
sendstr.attachCamera(mycam);
//we pass mycam into receive
sendstr.send("receive",mycam);
}
public function receive():void
{
video = new Video(put-width-here, put-height-here);
video.attachCamera(mycam); // mycam needs to be a class variable, not local to "send()";
mybitmap = new BitmapData(fill parameters here);
update();
}
public function update() {
mybitmap.draw(video);
// do stuff to your bitmap here...
}

I'm trying to use certain icon instead of default Xamarin.Forms pins on Map.
So I created CustomisePin class that inheritance Pin.
using Xamarin.Forms.Maps;
namespace agroNet.Tools
{
public class CustomPin : Pin
{
public string PinIcon { get; set; }
}
}
Here is what I tried in my ViewModel
private Map _map;
public IrrigNetViewModel(Map map)
{
dialog = UserDialogs.Instance.Loading(AppResource.LocalizationResource.Loading);
TabTappedCommand = new Command((tabName) => OnTapClicked(tabName.ToString()));
HideListOnTapCommand = new Command(HideListOnTap);
_map = map;
GetData();
}
And here is method wor set pins on positions.
public void LoadMapTab()
{
//var irrigNetPins = new List<CustomPin>();
foreach (var item in IrrigNetCollection)
{
//var pins = new CustomPin
//{
// Label = item.StationName,
// Position = new Position(item.StationLatitude, item.StationLongitude),
// PinIcon = "satellite.png"
//};
_map.Pins.Add(new CustomPin
{
Label = item.StationName,
Position = new Position(item.StationLatitude, item.StationLongitude),
//PinIcon = P
});
_map.MoveToRegion(
MapSpan.FromCenterAndRadius(new Position(item.StationLatitude, item.StationLongitude),
Distance.FromKilometers(30)));
//irrigNetPins.Add(pins);
}
//return irrigNetPins;
}
In LoadMapTab under the comment lines is what I have tried to set pin icon.
And here is part of View if it's important because of Binding Context.
public partial class IrrigNetPage : ContentPage
{
public IrrigNetPage()
{
InitializeComponent();
BindingContext = new IrrigNetViewModel(MainMap);
}
}
I find some examples on Google, like:
https://github.com/raechten/BindableMapTest
https://github.com/paulpatarinski/ShouldIWashMyCar
For some reason I can't event run them, but still I tried to use code and no matter what I have Pin are alwas default, or not even show.
What is simple way to set certain icon for pin and is it posiple to render it just with some path to the icon without rendering map also (Because I saw many create costumise map for customised pins).
Also If it's important for someon I'm using MVVM patern.
The official Xamarin sample and documentation is outdated. I modified the official Custom Pin sample in order to use custom pins in iOS and Android. The project is hosted on GitHub.
An issue is reported about the official sample over here.
When I instantiate a new StageVideo instsance with stage.stageVideos[0] everything works great, but when i leave my view that's displaying the video it sticks on the stage. So when i goto another view it's still showing on the stage in the background. I tried setting sv = null, removing event listeners...etc.
I've created a StageVideoDisplay class which is instantiated in mxml like: and on view initialization i call a play() method:
if ( _path )
{
//...
// Connections
_nc = new NetConnection();
_nc.connect(null);
_ns = new NetStream(_nc);
_ns.addEventListener(NetStatusEvent.NET_STATUS, onNetStatus);
_ns.client = this;
// Screen
_video = new Video();
_video.smoothing = true;
// Video Events
// the StageVideoEvent.STAGE_VIDEO_STATE informs you whether
// StageVideo is available
stage.addEventListener(StageVideoAvailabilityEvent.STAGE_VIDEO_AVAILABILITY,
onStageVideoState);
// in case of fallback to Video, listen to the VideoEvent.RENDER_STATE
// event to handle resize properly and know about the acceleration mode running
_video.addEventListener(VideoEvent.RENDER_STATE, videoStateChange);
//...
}
On video stage event:
if ( stageVideoInUse ) {
try {
_rc = new Rectangle(0,0,this.width,this.height);
_sv.viewPort = _rc;
} catch (e:Error) {}
} else {
try {
_video.width = this.width;
_video.height = this.height;
} catch (e:Error) {}
}
And on stage video availability event:
protected function toggleStageVideo(on:Boolean):void
{
// To choose StageVideo attach the NetStream to StageVideo
if (on)
{
stageVideoInUse = true;
if ( _sv == null )
{
try {
_sv = stage.stageVideos[0];
_sv.addEventListener(StageVideoEvent.RENDER_STATE, stageVideoStateChange);
_sv.attachNetStream(_ns);
_sv.depth = 1;
} catch (e:Error) {}
}
if (classicVideoInUse)
{
// If you use StageVideo, remove from the display list the
// Video object to avoid covering the StageVideo object
// (which is always in the background)
stage.removeChild ( _video );
classicVideoInUse = false;
}
} else
{
// Otherwise attach it to a Video object
if (stageVideoInUse)
stageVideoInUse = false;
classicVideoInUse = true;
try {
_video.attachNetStream(_ns);
stage.addChildAt(_video, 0);
} catch (e:Error) {}
}
if ( !played )
{
played = true;
_ns.play(path);
}
}
What happens is in the view when i navigator.popView(), the stageVideo remains on the stage, even in other views, and when returning to that view to play a different stream the same stream is kind of "burned" on top. I can not figure out a way to get rid of it! Thanks in advance!
In Flash Player 11, Adobe added the dispose() method to the NetStream class.
This is useful to clear the Video or StageVideo object when you're done with it.
When you call the dispose() method at runtime, you may get an exception indicating that there is no property named dispose on the NetStream object.
This occurs because Flash Builder is not compiling the app with the proper SWF version. To fix that, just add this to your compiler directives:
-swf-version=13
In the new Flash Builder 4.7, we hopefully won't have to specify the SWF version to use the newer Flash Player features.
This seems to be the best solution, but if you can't use Flash 11 (or the latest Adobe AIR), some other work arounds would be:
set the viewPort of stage video object to a rectangle that has width=0 and height=0
since stage video appears underneath your app, you can always cover the viewport (with a background color or some DisplayObject)
Ok the issue was actually that, even though it seemed like stage video was in use since i got the "Accelerated" message in status, that it was actually the video render even running and classic video was actually in use. The only thing I needed to do was add stage.removeChild( _video ) to the close() event in the class!!
I am trying to make a simple mp3 player using flash. The songs are loaded using an XML file which contains the song list. I have "play" button with the instance name "PlayBtn". I have an actionscript file named "playctrl", the content of which are listed below:
package classes
{
import flash.media.Sound;
import flash.media.SoundChannel;
import flash.events.*;
import flash.events.MouseEvent;
import flash.net.URLRequest;
public class playctrl
{
private var MusicLoading:URLRequest;
private var music:Sound;
private var sc:SoundChannel;
private var currentSound:Sound;
private static var CurrentPos:Number;
private var xml:XML;
private var songlist:XMLList;
private static var currentIndex:Number;
public function playctrl()
{
music = new Sound();
currentSound= music;
CurrentPos = 0;
currentIndex = 0;
}
public function success(e:Event):void
{
xml = new XML(e.target.data);
songlist = xml.song;
MusicLoading = new URLRequest(songlist[0].file);
music.load(MusicLoading);
}
public function playSong(e:Event):void
{
if(sc != null)
sc.stop();
sc = currentSound.play(CurrentPos);
trace("HELLO !!!");
}
}
}
I have a second file named "play.as", the content of which is listed below:
import classes.playctrl;
var obj:playctrl = new playctrl();
var XMLLoader:URLLoader = new URLLoader(); //XML Loader
XMLLoader.addEventListener(Event.COMPLETE, obj.success);
XMLLoader.load(new URLRequest("playlist.xml"));
PlayBtn.addEventListener(MouseEvent.CLICK, obj.playSong);
However on clicking the play button, I notice that the function playSong() is called 7-8 times(check by printing an error msg. inside the function) resulting in overlapped audio output and the player crashing as a result. The function should be called only once when the MouseEvent.CLICK is triggered. Please help ...
interestingly, sound object doesn't have a built-in "isPlaying" boolean property (strange), so you could just create your own.
var isPlaying:Boolean
function playSong():void
{
if(!isPlaying)
sound.play();
}
function stopSong():void
{
if(isPlaying)
{
channel.stop();
isPlaying = false;
}
just a note: by convention, class names are capitalized camel case while instance names are uncapitalized camel case. so your playctrl.as class file should (or could) be PlayCtrl.as, and your PlayBtn instance should (or could) be playBtn.
Edit:
The title of your question is a bit misleading, the answer I gave you is a solution to the question expressed in the title.
Looking at your code, I would look at separating the concerns, on one hand you want to load the song data, on the other hand you want to control the sounds. I would implement separate classes for each concern. If you create a separate class for your player control, you'll be able to dispatch event within that class without the event bubbling all over your app and calling your functions several times.
//Previous answer
You could do this by implementing a Boolean that would be set when the sound is stopped or played.
In any case here's another way to filter unwanted clicks
private function playSong(event:MouseEvent ):void
{
// set up a conditional to identify your button ,
// here's an example...
if( event.currentTarget.name is "PlayBtn" )
{
//do whatever
//then...
event.stopImmediatePropagation();
}
}
This being said, in your case , it sounds like a bit of a quick fix since a MouseEvent shouldn't trigger the play function several times...
It would make sense to debug your code in order to understand why several events are dispatched after a Mouse click
private var _isPlaying:Boolean;
public function playSong(e:Event):void
{
if(sc != null)
{
sc.stop();
_isPlaying = false;
}
if( !_isPlaying )
{
sc = currentSound.play(CurrentPos);
_isPlaying = true;
trace("HELLO !!!");
}
}
I am trying to write an application, but it is constantly crashing when using the uiimagepickercontroller. I thought that it might be because I was not disposing of the picker after each use, but it will often freeze up on first run as well. Usually I'll take a picture and it just freezes, never asking to "use" the picture.
Do you have any suggestions? Here is my code. Has anyone gotten this to work?
public override void ViewDidLoad ()
{
base.ViewDidLoad ();
myPicker = new UIImagePickerController();
myPicker.Delegate = new myPickerDelegate(this);
myAlbumButton.Clicked += delegate {
if(UIImagePickerController.IsSourceTypeAvailable(UIImagePickerControllerSourceType.PhotoLibrary)){
myPicker.SourceType = UIImagePickerControllerSourceType.PhotoLibrary;
myPicker.AllowsEditing = true;
this.PresentModalViewController (myPicker, true);
}else{
Console.WriteLine("cannot get album");
}
};
myCameraButton.Clicked += delegate {
if(UIImagePickerController.IsSourceTypeAvailable(UIImagePickerControllerSourceType.Camera)){
myPicker.SourceType = UIImagePickerControllerSourceType.Camera;
//myPicker.AllowsEditing = true;
this.PresentModalViewController (myPicker, true);
}else{
Console.WriteLine("cannot get camera");
}
};
}
private class myPickerDelegate : UIImagePickerControllerDelegate
{
private TestView _vc;
public myPickerDelegate ( TestView controller):base()
{
_vc = controller;
}
public override void FinishedPickingImage (UIImagePickerController myPicker, UIImage image, NSDictionary editingInfo)
{
// TODO: Implement - see: http://go-mono.com/docs/index.aspx?link=T%3aMonoTouch.Foundation.ModelAttribute
_vc.myImageView.Image = image;
myPicker.DismissModalViewControllerAnimated(true);
}
}
Try to call your event handlers code from the main thread by using BeginInvokeOnMainThread().
So my issue was very similar.
Instead of having a delegate class, I had the delegates inline for the picker.
For some reason the app froze every time after talking the image, not stopping in any breakpoint after that.
The solution that worked for me was to use this book:

I'm trying to use the native flex serialization/deserialization process to save/load state of a workspace in flex. In order to save or load a file I have to use my servlet, which just bounces back the bytes from the input stream to the output stream. Here's a basic outline of my Flex code:
Serialized Object Container:
public class MyWorkspace {
public var id : String;
public var url : String;
public var objectCollection : ArrayCollection; // Contains MySubObjects
}
Serialized sub object:
public class MySubObject
{
public var name:String;
public var csv:String;
}
Visual Element Constructor:
public function VisualSandbox(){
registerClassAlias("MyWorkspaceAlias", MyWorkspace);
registerClassAlias("MySubObjectAlias", MySubObject);
}
Visual Element Event Handlers:
public function onSaveButtonClick(event : MouseEvent) : void
{
var ws : MyWorkspace = new MyWorkspace();
ws.id = "ID";
ws.url = "URL";
ws.objectCollection = new ArrayCollection(veObjCollectionAC.source.slice());
var ba : ByteArray = new ByteArray();
ba.writeObject(ws);
ba.position = 0;
var fr : FileReference = new FileReference();
// There's no need for me to put the rest so
...
fr.download(urlRequest, "workspace.ws");
}
public function onLoadButtonClick(event : MouseEvent) : void
{
veFileReference = new FileReference();
veFileReference.addEventListener(DataEvent.UPLOAD_COMPLETE_DATA, loadCompleteHandler);
// This part works as well so I'm skipping it.
}
public function loadCompleteHandler(event : DataEvent) : void
{
// Pretend I loaded "workspace.ws" by bouncing it off of my servlet byte for byte.
var ba : ByteArray = new ByteArray();
ba.writeObject(event.data);
ba.position = 0;
var obj : * = ba.readObject();
trace(obj is MyWorkspace); // Prints false
}
So my problem here is not with the saving of the workspace. That works great. My problem is with the loading of a workspace. The event.data that I write to the byte array is not reconstituted into a MyWorkspace object even though it is exactly what I wrote to the file.
There has to be a way of making a MyWorkspace object from the data, but I can't figure it out. Has anyone tried to do this before?
Thanks!
I've figured out what the problem here is. It specifically has to do with the line:
ba.writeObject(event.data);
The data field of the event, being a DataEvent, is specifically of type String. ByteArray.writeObject() puts a type code at the beginning of the byte array. This took me many hours of looking at Hexplorer to figure out why, exactly, the byte array had 2-3 extra characters at its beginning.
My current best solution for this is to change that line as follows:
for (var i : int = 0; i < event.data.length; ++i)
{
ba.writeByte(event.data.charCodeAt(i));
}
This ensures that the byte array is exactly the same as what was saved to my local drive and bounced off my servlet.
After doing this, trace(obj is MyWorkspace) prints true.
Hope this helps someone else in the future!
Have you tried casting the value?
var obj : MyWorkspace = ba.readObject() as MyWorkspace;
