NetConnection and NetStream in Director: Is it impossible to have more than one incoming Stream?

forums_noreply@adobe.com — Tue, 07 Oct 2014 18:06:41 GMT

Hi there,

I'm working on a Director 11.5 video chat for 3 people. You shall see your webcam video as a little and the two you are connected with as a big video panel. So good so far, I managed to show my own webcam video without streaming it and managed to see one of the others as an incoming stream.

The problem is: as soon as there's a second script initiating a second InStream (no matter how I name it), only the one with the lower sprite number shows it's stream. When I disable the script for this lower sprite, then the second one is playing, so it can't be due to an incorrect script.

I already emilinated two misstakes which made it not working at all at the beginning:

First I tried to use the NetConnection object (for sending my own video stream, works fine) also for creating an input stream. That didn't work. It's a different scene where I set up and play the inStreams (I made the NetConnection object global). So now I set up a new NetConnection for each stream: one outStream and two inStreams.

First I also used only one swf member and made several sprites of it. This didn'Ät work at all, also using the same behavior for the two other-perople-players. So i copied ad pasted the swf and also the behavior. I also renamed every variable in the second behavior with a "2" at the end, just to be sure.

Then it worked at least - but still only for one inStream.

The architecure of my Director film is the following:

I've got two scenes. First scene is an input field to type your name and a "connect" button. Behind this button there's a behavior setting a connection to the server (by using a swf sprite which isn't visible yet) and sending my webcam video and name to the server. This part works fine.

(Picture shows scene 2)

Second scene consists of three swf sprites - one is to show my own webcam video directly from PC. This one already existed in the first scene, for I have to use a swf for setting up a NetConnection. The second and third swf sprites are connected to a behavior script which sets up a new connection (in exitFrame, with a bool variable "firsttime" to make sure it only happens once).

I also have two drop down field each below a partner chat swf. Here I show all people who are logged in at the server, it automatically updates. The one you chose in the drop down is the video you will see in the swf sprite above. Thid works fine (if it works with the inStream).

The script for playing the own webcam video is placed at the first frame of the second scene and only refers to the swf for my own video (which already occurs in scene 1). Well, that's all I think. I'll post the code for the two partner player swf here. Please have a look at it to find a misstake - or maybe again it's some strange Director behavior (like two sprites of one member didn't work) which I cannot think of...

Code for the behavior script of the partner swf for partner 1. The script for partner 2 is exactly the same, but every variable has a "2" at it's end.

global firsttime1
global gUserList

property gNetConn
property InStream

on exitFrame  me 
  if (firsttime1) then   
    pSprite = sprite(me.spritenum)   
    gNetConn = pSprite.newObject("NetConnection")   
    gNetConn.connect("rtmp://212.122.56.2/flashcam")   
    InStream = pSprite.newObject("NetStream", gNetConn)    put "InStream " & InStream
    InStream.play(gUserList[1])   
    pVideoClip = pSprite.getVariable("VideoClip",FALSE)
    put "pVideoClip " & pVideoClip
    pVideoClip.attachVideo(InStream)   
    firsttime1 = false
  end if 
end exitFrame

on updateInStream aArg1, aArg2
-- that method is called by the drpdown script when some change occured 
  put "neuer Partner 1: " & aArg2
  partner = aArg2
  InStream.play(partner)  
end updateInStream

on endsprite me 
  if not(voidP(InStream)) then
    InStream.close()
  end if   
end endsprite

I'd appreciate every idea or help! Thank you!

Strange error: "Handler not found in object: #newObject" (at a sprite object)

forums_noreply@adobe.com — Sun, 28 Sep 2014 08:02:58 GMT

Hi there,

I'm facing a strange error in Lingo. I'm using Director 11.5 on Windows 7.

First I was reconstructing a tutorial for netConnection in Director. This worked fine.

Then I added some further functionality and then - a strange error occured where nothing much has been altered and which was working fine before. Now Lingo doesn't know the handler "newObject" at the sprite pSprite anymore! Why???

The regarding code for this error is a behavior for the button to connect. The code is the following:

global pNetConn
global gUserList
property pSprite

on beginSprite (me)    
  pSprite = sprite(me.spriteNum)
  pSprite.cursor = 280  
end beginSprite




on mouseDown (me)  
  sIch = me.stripSpaces( sprite(3).text ) 
  put "eigener Name ist: "& sIch
  if ((sIch = "") or (sIch = void)) then    
    alert "Bitte geben Sie Ihren eigenen Namen an."     
  else       
    gNameSelbst = sIch    
    if voidP(pNetConn) then
      me.setConnection()
    end if
    me.getUserList()    
    go frame(23)      
  end if  
end mouseDown





on setConnection me  
  pNetConn = pSprite.newObject("NetConnection")  
  pSprite.setCallback(pNetConn,"onStatus",#statusUpdate,me)
  pSprite.setCallback(pNetConn,"clientListChannel",#userListUpdate,me)
    tURL = "rtmp://xxxxxxxx"
  pNetConn.connect(tURL)  
end setConnection


on statusUpdate aArg1, aArg2  
  if (aArg2.code = "NetConnection.Connect.Success") then    
    -- Hier erfolgt später die Sendung des eigenen Videostreams an den Server
  end if  
end statusUpdate





on userListUpdate aArg1, aArg2  
  luserList = aArg2  
  if   (luserList <> void) then    
    put "-----USER-LIST UPDATE------"
    gUserList = []    
    repeat with counter = 0 to luserList.length -2      
      sname = luserList[counter].label
      gUserList.add(sname)  
    end repeat    
  end if  
end userListUpdate



on stripSpaces (me, aString)  
  -- clear all spaces from the string
  repeat while offset(SPACE,aString)
    tCharIndex = offset(SPACE,aString)
    delete aString.char[tCharIndex]
  end repeat  
  -- return the string
  return aString  
end

The tutorial code which works is the following:

Here the netConnection is built in the on exitFrame - but I already tried this in my new code above without any success. By the way, I intentionally xxx-ed the URL ;-) Of course in the original there's a correct server adress.

global gNames
property pCamera
property pInStream
property pMicrophone
property pNetConn
property pOutStream
property pSprite

on exitFrame (me)
  if voidP(pNetConn) then
    me.initiateConnection()
  end if  
end exitFrame

on initiateConnection (me)
  pSprite = sprite(me.spriteNum)
  pNetConn = pSprite.newObject("NetConnection")
  pSprite.setCallback(pNetConn,"onStatus",#myOnStatus,me)
  tURL = "rtmp://xxxxxx"
  pNetConn.connect(tURL)
end initiateConnection

on initiateStreams (me)
  tCamObj = pSprite.newObject("Camera")
  pCamera = tCamObj.get()
  tMicObj = pSprite.newObject("Microphone")
  pMicrophone = tMicObj.get()
  pOutStream = pSprite.newObject("NetStream",pNetConn)
  pOutStream.attachAudio(pMicrophone)
  pOutStream.attachVideo(pCamera)
  pOutStream.publish(gNames.publishName,"live")
  pInStream = pSprite.newObject("NetStream",pNetConn)
  pInStream.play(gNames.subscribeName)
  pVideoClip = pSprite.getVariable("VideoClip",FALSE)
  pVideoClip.attachVideo(pInStream)  
end initiateStreams

on endSprite 
  if not( voidP(pOutStream) ) then
    pOutStream.close()
  end if
  if not( voidP(pInStream) ) then
    pInStream.close()
  end if  
  if not( voidP(pNetConn) ) then
    pNetConn.close()
  end if  
end endSprite

on myOnStatus me, aArg1, aArg2  
  put aArg2.code  
  if (aArg2.code = "NetConnection.Connect.Success") then    
    me.initiateStreams()    
  end if  
end myOnStatus

Did anybody ever face the same error? Can anyone tell me where the misstake lies? Or is it a kind of bug? I really don't knwo what could be wrong. I'd appreciate any help!

Thanks

Startup problems using NetConnection and NetStream to FMS

forums_noreply@adobe.com — Mon, 15 Sep 2014 16:40:00 GMT

Hi there,

unfortunately I'm a noob at Director and my task is to build a simple 2-people-video chat. I'm using Director 11.5, Windows 7 and Flash Media Server 3 (well, not sure about the version, but an old one).

I found out that I can use a NetConnection-object in Director to connect to the server. But my only information source is the user manual:

http://help.adobe.com/en_US/Director/11.5/UsingScripting/WSc3ff6d0ea77859461172e0811d50262 762-7f24.html

There only are some single code lines without any details. So my code looks like this until now --- I didn't replace any of the sample code, just copied all I would like to use somehow.

  myNetConObject = sprite(1).newObject("NetConnection")
  myStream = sprite(1).newObject("NetStream", myNetConObject)
  myStream.attachVideo(source)
  myStream.attachAudio(source)
  mystream.publish(whatToPublish)
  mystream.play(whatToPlay)

The manual unfortunately does NOT tell me HOW I can give the parameters, for example the source of a camera video. Has it to be the installation URL of the camera? Has it to be the name of the camera? Do I have to set up an "source" object somehow and attach a camera to that? Same thing with the micro.

Next: what is "whatToPublish" and "whatToPlay"? Shall it be the attached video (and how shall I name that)? Shall it be just "video"? (for publidhing.) Shall it be an url for play?

Also: how do I get logged in with a user name and how can I play a stream of another user?

Somehow I'm very frustrated about the help documents... These example lines didn't help me, because they're not giving any specification what parameters really are needed and such things.

Can someone help me please? I'd also be glad about links to tutorials or other forum questions about that. Didn't find any myself.

Thanks in advance fr your help and hints!

How to get list of logged-in users from Flash Media Server in a Flash programm? (Or login/logout notifications)

forums_noreply@adobe.com — Sun, 07 Sep 2014 11:38:06 GMT

Hi there,

I'm Very sorry for asking this. I guess it's a very basic problem, but I'm very new to Flash and Flash media Server and I need a very fast answer...

Currently I'm working on a Director project using a flash program which connects to Flash Media Server (I guess version 3, it's quite old). Unfortunately they forgot to make a flash method to send the actual userlist (or a notification when someone logged in or out) to Director. AND, unfortunately, they lost the source code of that flash programm, so I cannot look into it or alter it *sigh*.

Now I want to do a new flash programm which covers the old one, letting all known methods "pass trough" and building an additional method to gain the user list (or login/out notification).

How do I get the login information from Flash Media Server? (Would be good if you could provide an idea already for flash code... as I said I'm a tard at flash till now)

Thank you so much. And I hope you understand my situation asking here...

Are there any Director scripts resp. code beyond "cast members"?

forums_noreply@adobe.com — Fri, 22 Aug 2014 14:53:36 GMT

Hi there,

currently I'm working on a big, hardly documented project in Director/lingo without having built it myself. So I'm faced with a lot of problems and questions.

(I'm working with the German edition, so maybe some of my translated English Director terms are not correct.)

This time I'm facing a very strange behavior of the application. There is a parent script named "PersonalZelle" (personal cell) which has a function named "switchCameraCB". I didn't find any call of this function via text search in other scripts. I already tried chosing to search in "all cast members" (German: "Alle Besetzungen"). But placing a breakpoint there and debugging it, this function is actually used in the running application! Ô.ô How can that be?

So my questions are:

1) Are there any "hidden" scripts/code beyond cast members? If so, how do I find them?

2) If not, how is it possible to have a function/method being used if no code actually calls it?

Second example:

In another script, there is a variable named piVideoNum. This variable is NOT instanciated and no value is given to it in the whole code. But debugging it, it always has the correct value which it should have. How can that be? Ô.ô where does it take the value from? As far as I know there is no UI-part having this variable attached. In the UI, you have three videos which you can klick, and if klicked, the correct number of the video is saved in piVideoNum. But in the attached behavior script there is nothing. The method which handles the klick calls another method and sends the piVideoNum - without having altered it before. Maybe it's also done by some "hidden" script/code?

Does anyone have an idea? This would be very helpful!

I need to alter this method, but if I don't know how it is working, there's no possibility...

Urgent: How to export a Director cast member - in this case it's a flash movie?

forums_noreply@adobe.com — Mon, 30 Jun 2014 15:05:02 GMT

Hi there,

I've got a problem - of course, that's why I'm here.

My problem is that in my Director (version 11.5) movie a flash movie is member of the cast list (sorry, I only know the German terms and hope totranslate correctly!). In it's properties there's no source-URL. So it must be "in" the Director film somehow.

Unfortunately the original file went lost. Now I need to have this flash movie as a flash movie, not as a member/ cast. Is there any possibility to get the movie out of Director als a file?

Thanks so much for your help!

Kind regards

Jana
