The Red5 server can only support .flv or .mp4 format files. So how you are 
converting image file into .flv or .mp4 format and how you are upstreaming it.

What steps will reproduce the problem?
-------------------------------
1. Downloaded the following files into 
"<RED5_TOP_DIR>/dist/webapps/red5-screenshare"...
- screenshare.jar
- screenshare.jnlp
- publisher.swf

2. Modified screenshare.jnlp as follows...
<jnlp spec='1.0+' codebase='http://<MY_IP_ADDRESS>:5080/red5-screenshare' 
href='screenshare.jnlp'> 
...
    <application-desc main-class='org.redfire.screen.ScreenShare'>
        <argument><MY_IP_ADDRESS></argument> 
        <argument>red5-screenshare</argument> 
        <argument>1935</argument> 
        <argument>screen_share</argument>       
    </application-desc> 

3. Launched Red5 server. (Verified it's correct operation using the included 
demo applications e.g. oflaDemo). 

4. Launched screenshare.jnlp and clicked "start Sharing". 

What is the expected output? What do you see instead?
------------------------------------------
I expected my desktop to be streamed to the Red5 server and consequently to the 
Internet. 

Instead, I get the following error in my Red5 output log... 

     ...

--------------------------------------
I want to be able to view my server's desktop from another computer by pointing 
the client machine's browser to the Red5 server. Do I need to do anything more 
than copy the jnlp and jar to a directory under my Red5 directory? Perhaps I 
need metadata files? Any help would be greatly appreciated as I'm obviously new 
to this. 

What steps will reproduce the problem?
1. Copy the complete screen share directory to /usr/local/red5/webapps
2. edit .jnlp file
3. run the jnlp

What is the expected output? What do you see instead?
Unable to share the screen after clicking Start Sharing button.

Please provide any additional information below.
I am using this screenshare in Linux environment, what are the files that I 
should update and what values. If I use in windows it's working properly.
Please provide me the solution.

What steps will reproduce the problem?
1. Download screenshare.zip
2. Placed the folder under red5/dist/webapps/
3. modified the screenshare.jnlp as 
<jnlp spec='1.0+' codebase='http://localhost:5080/screenshare'

    <application-desc main-class='org.redfire.screen.ScreenShare'>
        <argument>localhost</argument> 
        <argument>screenshare</argument>

        <argument>screen_share</argument>   
        <argument>flashsv2</argument>       
    </application-desc> 
4.Modified the screenviewer.html as
              var stream = getPageParameter('stream','screen_share');
          var url = getPageParameter('url', 'rtmp:/screenshare');
          var control = getPageParameter('control', 'true');

I launched the screenshare application using 
http://localhost:5080/screenshare/screenshare.jnlp and clicked "start 
Sharing",the screen is shared as expected and can be viewed in the preview 
window

What is the expected output? What do you see instead?

When I hit tthe accessor URL i.e 
http://localhost:5080/screenshare/screenviewer.html I am able to see the shared 
screen but the screen width starts shrinking and makes it unable to view the 
shared screen i.e the video stream

Hello,

I'm recording screenshare on red5 0.8.0. However i cannot seek the recorded 
file to the needed possition. For example there are only four keyframes in meta 
file of 1 minute record.

Tried to record it on Wowza and the result was the same -  impossible to seek. 
The same problem is with both older and newer versions of red5-screenshare.

Is it the problem of timestamps calculation in red5-screenshare, isn't it? How 
to fix the seek problem?

Hi, 

We are trying to integrate the screenshare with our red5 instance. I was 
wondering if you can provide me with a link of your libs that are necessary for 
compilation, because it is really hard to make them work all together.

A zip of the lib-folder would be like a Christmas gift for me.

Kind regards,

Nikola Yovchev

Loading screenshare.jnlp on Chrome causes the file to download.  Then the user 
needs to explicitly save the file, then run it.

Is there a way around this issue?  Also, is it possible to embed 
red5-screenshare as an embedded applet right with a page?

Thaks.

What is the problem?

My screen sharing works, but i, am not able to control the remote PC.

initial commit

Please provide any additional information below.

What steps will reproduce the problem?
1. While sharing desktop text clarity is very poor.
2. Please give me any suggestion to improve the text clarity

What is the expected output? What do you see instead?

While sharing the screen text clarity is very poor comparative with original 
screen.I am enclosing original and shared screens images below. Please find the 
attchments.

What version of the product are you using? On what operating system?

Please provide any additional information below.

What steps will reproduce the problem?
1. The source producer can upload part of his screen in whatever Width and 
Height. But the viewer will not know what the figure is.
2. The HTML page of viewer set the screen to be 100% but of the viewer screen, 
not the original streaming video. 
3. pixels on viewer screen are deformed due to the scaling to the view port 
size. The outcome is poor visual quality. 

What is the expected output? What do you see instead?
The view should be able to check the resolution of streaming video then adjust 
its own view port size. The displaying pixel scale must always be 1:1. Or else, 
the viewer swf play should do smart scaling with filter -- that will be more 
complicate of course.  Maybe, the resolution of the crop area should send to 
server, and let viewer re-adjust the viewing area automatically ( at least 
reflect the figure on viewer's parameters on HTML page)

What version of the product are you using? On what operating system?
screenshare-red51RC3.zip, the viewer have been tested on WinXP, Win8 and Win7.

Please provide any additional information below.
Is there any instruction of the parameters parsing to SWF player. I want to use 
flowplayer or HTML5.

Thank
Herrick

I would love to have a parameter that defines the fps of the screensharing and 
also be able to control how many dropped frames should be dropped to catch up 
to realtime. 

Do you think we could implement it into a new release of this?

Cheers
Thomas

What steps will reproduce the problem?
1. Deploy the latest screenshare.jar
2. Attempt to access it with a system configured with java 1.5 (in this case, a 
PowerBook G4 with 10.4.1, but I think its the java version that is the problem).

What is the expected output? What do you see instead?
The screenshare window to show up as usual

What version of the product are you using? On what operating system?
I've tried it with today's (Nov. 12), but previous versions fail as well.

Please provide any additional information below.
Any chance we it can be compiled with target java version 1.5?  Or am I missing 
something?

Hi,

we're just trying to integrate the red5-screenshare with our own eclipse-rcp 
Application. The main Problem with this solution seems the massive 
library-dependency of the red5.jar. You propose that one could use the 
commercial smaxe project as the rtmp-client. 

What do you think about flazr? This is an opensource rtmp-client. I've managed 
to send an flv or fv4-file to the red5-streaming server with no effort. Would 
it be possible to use this library instead of red5? The library is much smaller 
(with dependencies 1.5mb compared to 6mb of the red5 solution).

Best regards

Johannes Michler

We're are doing a system where we need not only to stream live, but also record 
screenshare. Red5-screenshare is the great project and suits our needs quite 
well, but i see, that parameter 'live' is hardcorded in ScreenShare.java and 
server does not record stream. I extracted jar file, edited ScreenShare as i 
need (changed live to record) and run do_compile and do_makejar scripts. 
However it looks new jar file does not work when i run screenshare.jnpl. 

How to solve that problem? How to make jar which would work and record the 
stream. Maybe it's "newbie's" question, but it makes me headache... I'd 
appreciate any help.

My email's [email protected]

What steps will reproduce the problem?
1. Start the screen Share
2. Share dark colors
3. See the result, it will absolutely not display anything, works marvelously 
on light colors and as soon as you get in more colors it completely stop 
updating blocks... my guess is the WriteShort function but 
i can't fix it...

What is the expected output? What do you see instead?
Same image as what is shared...

Please provide any additional information below.

What steps will reproduce the problem?
1. Screenshare.jar and jnlp
2.
3.

What is the expected output? What do you see instead?
I am running the red5 server ie localhost:5080 and then download your 
screenshare and to run it using do_run2.cmd that says ""C:\Program 
Files\Java\jdk1.6.0_24\bin\java" -classpath screenshare.jar 
org.redfire.screen.ScreenShare localhost screenshare 1935 screen_share flashsv2 
pause" command line that shows the screenshare java console and tried to 
connect "start sharing" but does not work through screenviewer.html
Let me know if you have any ideas 

What version of the product are you using? On what operating system?
red5 and Windows

Please provide any additional information below.

What steps will reproduce the problem?
1. Remove Internet connection
2. Opem screenviewer.html on client PC
3. After a short period of time, Error #2032 displayed

What is the expected output? What do you see instead?

I expect to see the local RTMP broadcast, instead I get the error. Looking in 
the javascript console I see the following:

GET http://fpdownload.adobe.com/pub/swz/crossdomain.xml 
GET http://fpdownload.adobe.com/crossdomain.xml 
GET http://myserver:5080/screenshare/textLayout_1.1.0.604.swz 404 (Not Found)

What version of the product are you using? On what operating system?

Using the Apr 2011 release in the download area.


Please provide any additional information below.

If I allow access to fpdownload.adobe.com on the client PCs, the plugin 
loads/runs successfully.

I am developing some sample desktop sharing application with the help of red5 
screenshare. It is working fine as expected. But only problem i am facing is 
Text clarity is very poor while sharing. Please give me any suggestions to 
improve the text clarity.

  Here i am enclosing screenshots of original image and shared image.Please find the attachments.Thanks in advance.

What steps will reproduce the problem?
1. I have a red5 server configured to run on port 1935 for rtmp and port 80 for 
rtmpt. Server is not behind any firewall or proxy.
2. On the client's computer which is in a different network than the server's 
and also behind an http proxy, I run the jnlp file (configured on port 1935) 

What is the expected output? What do you see instead?

I expected that if rtmp is cut behind the proxy then the screen sharing 
application would switch to rtmpt. But this is not happening so I cannot use 
the screensharing application on this computer.

What version of the product are you using? On what operating system?
I am using latest version of the product on windows.

What steps will reproduce the problem?
1. When a try execute the command line 
2. click "Start Sharing"
3.

Can we get this applet to support RTMFP?
Currently I am running Flash Media Enterprise and having the applet send RTMP, 
and serverside, converting it to a rtmfp stream (which works).
But there is a few seconds delay due to the serverside converting.

Is it possible to have this applet do RTMFP?

Thank you!

I am trying to play the screenshare stream from an ordinary RTMP player like 
VLC.

What will be my full RTMP url for the live stream

rtmp://red5.mysite.com/oflaDemo/screen_share does not work.

I have copied the screenshare folder in the webapps folder of Red5. I have 
edited the screenshare.jnlp in this way:

<?xml version='1.0' encoding='utf-8'?>

    </application-desc> 
</jnlp>

and the screenviewer.html like this:

<html>
<head>
<title>ScreenViewer</title>
    <script type="text/javascript" src="swfobject.js"></script>
    <script type="text/javascript">

    var screenViewer = null;

    function setupApp()
    {
        screenViewer = document.getElementById("screenViewerID");

    }

    function stopApp()
    {
        if (screenViewer != null)
        {
            screenViewer.windowCloseEvent();
        }
    }

function getParameter(string, parm, delim) {

     if (string.length == 0) {
        return '';
     }

     var sPos = string.indexOf(parm + "=");

     if (sPos == -1) {return '';}

     sPos = sPos + parm.length + 1;
     var ePos = string.indexOf(delim, sPos);

     if (ePos == -1) {
        ePos = string.length;
     }

     return unescape(string.substring(sPos, ePos));
}

function getPageParameter(parameterName, defaultValue) {

    var s = self.location.search;

    if ((s == null) || (s.length < 1)) {
        return defaultValue;
    }

    s = getParameter(s, parameterName, '&');

    if ((s == null) || (s.length < 1)) {
        s = defaultValue;
    }

    return s;
}

    </script>
</head>
<body topmargin="0" leftmargin="0" bottommargin="0" rightmargin="0" 
onload="setupApp()" onUnload="stopApp()">
<div id="screenViewerDIV"></div>
<script type="text/javascript">

        var stream = getPageParameter('stream', 'screen_share');
        var url = getPageParameter('url', 'rtmp://localhost:5080/oflaDemo'');
        var control = getPageParameter('control', 'true');

        fo = new SWFObject("ScreenViewer.swf?rtmpUrl=" + url + "&recieverStream=" + stream + "&control=" + control, "screenViewerID", "100%", "100%", "9");
        fo.addParam("swLiveConnect", "true");
        fo.addParam("name", "screenViewerID");
        fo.write("screenViewerDIV");
</script>
</body>
</html>

and the command I enter is:

java -classpath screenshare.jar org.redfire.screen.ScreenShare localhost 
oflademo 1935 screen_share flashsv2

Everything looks correct and according to the instructions, but as I press the 
"start Sharing" button, it does not share. The following commands are displayed 
in the console:

Please help me to solve the issue. It is deeply important to deploy the desktop 
sharing on my localhost and then on our server. 

Thanks in advance!

What steps will reproduce the problem?
1.
2.
3.

What is the expected output? What do you see instead?


What version of the product are you using? On what operating system?


Please provide any additional information below.

What steps will reproduce the problem?
1. try to make Screen Area to be captured width or height less then zero, by 
mouse resizing.

What is the expected output? What do you see instead?
It shouldn't be less then zero, but it is.

Please provide any additional information below.

To fix it, you need to make some changes:

VirtualScreenWidthMouseListener.java: 
mouseDragged method should be (added newWidth check):

    public void mouseDragged(MouseEvent e) {
        double newX = e.getX();

        int delta = Long.valueOf(Math.round(this.x-newX)).intValue();
        int newWidth = VirtualScreenBean.vScreenSpinnerWidth-delta;

        //System.out.println(newX+"  "+newWidth);
        if ( ((VirtualScreenBean.vScreenSpinnerX+newWidth)<=VirtualScreenBean.screenWidthMax) && (newWidth >= 0)) {

VirtualScreenHeightMouseListener.java:
mouseDragged method should be (added newHeight check):

    public void mouseDragged(MouseEvent e) {
        double newY = e.getY();

        int delta = Long.valueOf(Math.round(this.y-newY)).intValue();
        int newHeight = VirtualScreenBean.vScreenSpinnerHeight-delta;

        //System.out.println(delta+" "+newHeight);
        if (((VirtualScreenBean.vScreenSpinnerY+newHeight)<=VirtualScreenBean.screenHeightMax) && newHeight >= 0) {

Than, you should recomplie, make jar, sign it and it's done!

Thanks for your project!
