How to use videoTransmit.java to broadcast live video?

The solutions has a sample code:videoTransmit.java,but how to configure it to capture the live video and broadcast?
of course,broadcast the V/A signal is the best.

I think AVTransmit2.java can transmit V/A signal together through the first parameter,but how to fill in the parameter?
If i fill in vfw://0,the live video signal transport
If I fill in javasound://8000,then the live audio transport
So the question is how to transmit the two signal together?

  • Can I broadcast live video for 1000 users?

    Hi:
    Is possible, using Flash Media Server, broadcast live video
    for 1000 users?,
    how much bandwidth do I need?,
    What system requeriment is need for this load (in linux)?,
    What maximum video size and fps is possible to get?
    regards,
    Christian

    You should have no problem serving a stream to 1000 users on
    a single server (a dual xeon/2bg ram box ought to do it).
    Your bandwidth requirements will depend on the bitrate of the
    video stream. Multiply the stream bitrate by the number of users
    (plus 1 for the publisher), and you'll get your bandwidth figure.
    For example, if the video is published at 300kbps, you'll use
    about 290mbps for your 1000 users.
    For the video size, I wouldn't go much larger than 640x480.
    The flashplayer doesn't use the video card to render video, and
    redrawing the screen with a large video chews through lots of
    processor cycles very quickly.

  • How to use the Java embedding activity in BPel

    hi all,
    How to use the java embedding activity in BPEL
    pls can u provide sample example

    1 Use [Oracle BPEL Process Manager Client Java API Reference|http://download-uk.oracle.com/docs/cd/B31017_01/integrate.1013/b28986/overview-summary.html] and especially [com.collaxa.cube.engine.ext|http://download-uk.oracle.com/docs/cd/B31017_01/integrate.1013/b28986/com/collaxa/cube/engine/ext/BaseBPELXExecLet.html]
    Instead of System.Out.println use addAuditTrailEntry(java.lang.String message)
    2. If you want to import a package write in code (Source View) of bpel process
    +<bpelx:exec import="package_name"/>+ for example +<bpelx:exec import="java.util.regex.Matcher"/>+
    example 1:
    String bodyAsString;
    StringBuffer myStringBuffer = new StringBuffer();
    try {
    bodyAsString = (String)getVariableData("BodyString");
    addAuditTrailEntry("bodyAsString1: "+ bodyAsString);
    Pattern pattern = Pattern.compile("goodDay");
    Matcher matcher= pattern.matcher(bodyAsString);
    while (matcher.find()) {   
    matcher.appendReplacement(myStringBuffer, "shitDay");
    matcher.appendTail(myStringBuffer);
    bodyAsString = myStringBuffer.toString();
    addAuditTrailEntry("bodyAsString2: "+ bodyAsString);
    } catch (Exception ex) {
    addAuditTrailEntry("Failed+bodyAsString",ex.getMessage());
    I put in code (Source View) the following
    <bpelx:exec import="java.util.regex.Matcher"/>
    <bpelx:exec import="java.util.regex.Pattern"/>
    example2:
    Object temp;
    try {
    temp = ((XMLElement)getVariableData("inputVariable","payload","/ns2:FiscalisMessage/ns2:Body")).getChildNodes().item(1);
    setVariableData("AdjReceipt",temp);
    addAuditTrailEntry("ok",temp.toString());
    catch (Exception ex) {
    addAuditTrailEntry("Failed :",ex);
    I put in code (Source View) the following
    <bpelx:exec import="oracle.xml.parser.v2.XMLElement"/>

  • Please could someone tell me where I can get info on how to use my controls when watching live sports on sky go on my IPad mini !!!

    Could someone please tell me where I can info on how to use the controls I.e live pause,forward,rewind etc when watching live shows on my ipad mini please.

    well, i can't really tell if i am only allowed one connection with this isp. basically, whenever i plug in the ethernet cord, all of the information gets filled in in the ethernet section of the network, except for the router info. there is router info filled in on my sister's computer whenever i plug the cord into her computer, though. does that mean i can't also use the modem for my computer? sorry, this is both my first time using a mac and my first time using anything other than dial-up, so i'm pretty lost. thanks for the info you've given me thus far.

  • How to publish multiple bit rate(MBR) live video?

    I've searched quite a few threads:
    http://www.developsigner.com/blog/2009/05/28/multi-bitrate-live-streaming-with-fmle-adobe- flash-media-live-encoder
    http://forums.adobe.com/thread/27371
    dynamicStream.addStream("livestream1",200);
    dynamicStream.addStream("livestream2",400);
    dynamicStream.addStream("livestream2",600);
    vid.play2(dynamicStream);
    But all of them are talking about playing multiple bit rate live video,
    my question is how I can publish multiple bit rate live videos in the first place?

    Thanks for your reply!
    But I need this to be done for each web user,
    so I can't require them to use FMLE themselves...

    How to do it??
    Any example??
    Thanks a lot!!

    Sorry, I think i did not express cearly. It is my fault.
    I re-write my requirements again:
    I have
    Class AAA1.java,
    Class AAA2.java,
    Class AAA3.java,
    Class AAA20.java...
    etc
    they all look like the program I posted first time,, once executed, they will run for ever, and they will be stopped until I press CRTL + C;
    Now I hope to use another java class StopProgram.java to stop them 1 by 1 or at once instead of pressing CRTL + C;
    In this case, how to code this StopProgram.java ??
    Thanks

  • How to use external Java API in Java Embedd inside BPEL

    How to use external classes inside the BPEL in Java Embed Activity ? Any sample code availble ? Like i want to use log4j API inside BPEL.

    No you dont have to change your startManagedServer.cmd/.sh everytime you need to have a Java Embedding activity. You only need it in case of using Log4J. As log4j requires a configuration xml viz log4j.debug.xml and log4j.dtd you need to let the soa managed server know about it. The best way to load this configuration files is using the JAVA_OPTIONS command during server startup.
    Hope the explanation helps.

  • [Solved] How to use Oracle Java 6 for specific applications

    I use an IDE called PyCharm. On its download page, it recommends using Java 6 instead of OpenJDK. I currently have jdk7-openjdk installed, and from what I had read in the Arch Wiki on Java, it should be possible to install Oracle Java 6 along side OpenJDK 7.
    However, after installing jdk6-compat and jre6-compat, I still see that I am running OpenJDK 7 when I run the following:
    % java -version
    java version "1.7.0_09"
    OpenJDK Runtime Environment (IcedTea7 2.3.3) (ArchLinux build 7.u9_2.3.3-1-x86_64)
    OpenJDK 64-Bit Server VM (build 23.2-b09, mixed mode)
    ...even after I have set JAVA_HOME and added /opt/java6/bin to my path.
    How can I get PyCharm (or other applications) to use Oracle Java 6 instead of OpenJDK?
    Thanks, and apologies if I've posted in the wrong place.
    Other information that might be helpful:
    Running zsh as default shell
    Using Gnome 3 as DE
    Last edited by Nikorasu (2012-11-17 20:54:33)

    I found the solution.
    For Pycharm, I just needed to add an environment variable PYCHARM_JDK. For running specific applications, I asked this question on the Unix / Linux StackExchange and got an answer there.
    Also, after running PyCharm in Java 6... I would not recommend it. OpenJDK works fine
