Video in applet
Hi,
Is it possible to insert a video clip in an applet?
You need the Java Media Framework for that. Google also finds this: [http://www.cs.cityu.edu.hk/~jia/cs4273/applet.doc] which has an example.

Hi all,
I have to create an applet which can record a video/audio from webcam and upload it to the server afterwards.
Can anyone help me create this?(JMF)
Or point me to a link where I can get some help regarding same.
Any help would be appreciated.
Regards,
Vikram Chhetryis it required for the client to have jmf installed on its machine.Obviously yaar,once you scroll down the article configuration ke baare mein usne discuss kiya tha..
David Fischer's application is not able to detect my
web cam. I m using quantum's webcam.well according to his point of view oo bandaa keh raha hein ki
Most of USB cameras.Kya aap USB cam hee use kaar rahe ho kya ??
why don't u give it a try with tht...
and the better advice which i can give it you use make a Swing application using JMF ensure tht everything is working fine.
Agaar woh theek raha toe applet ka zayadaa problem hooni nahin chahiye....

Show video while applet loading
Hi;
Is it possible to play a video during applet loading? The video format may be swf or flv anything. I can show an animated gif by using param tag. But i want to play a video.
Thanks in advance.
Edited by: akk512 on Jun 10, 2010 4:54 AMNot with current applet architecture, no.
But you might be able to do something clever with showing/hiding divs and javascript ... -
CTD bug in simple video streaming applet.
I'm trying to write a simple applet to use JMF to allow an end-user to view a video stream that's being served up by VLC. It doesn't have to look immensely pretty (in fact, streamlined is what I want most). I swiped some code from the jicyshout project (http://jicyshout.sourceforge.net) which handles streaming MP3s, and borrowed a framework for an applet from one of Sun's example applets for the JMF.
Here's my code so far:
** begin file SimpleVideoDataSource.java **
import java.lang.String;

import javax.media.protocol.*;
/* The SeekableStream and DataSource tweaks are based on the code from
* jicyshout (jicyshout.sourcefourge.net), which was written by Chris Adamson.
* The code was simplified (no need for mp3 metadata here), cleaned up, then
* extended for our puposes.
* This is a DataSource using a SeekableStream suitable for
* streaming video using the default parser supplied by JMF.
public class SimpleVideoDataSource extends PullDataSource {
protected MediaLocator myML;
protected SeekableInputStream[] seekStreams;
protected URLConnection urlConnection;
// Constructor (trivial).
public SimpleVideoDataSource (MediaLocator ml) throws MalformedURLException {
super ();

public void connect () throws IOException {
try {
URL url = myML.getURL();
urlConnection = url.openConnection();
// Make the stream seekable, so that the JMF parser can try to parse it (instead
// of throwing up).
InputStream videoStream = urlConnection.getInputStream();
seekStreams = new SeekableInputStream[1];
seekStreams[0] = new SeekableInputStream(videoStream);
} catch (MalformedURLException murle) {
throw new IOException ("Malformed URL: " + murle.getMessage());

Now, I'm still new to the JMF, so this might be obvious to some of you... but it's exploding on me, and crashing to desktop (both in IE and Firefox) with some very fun errors:
# An unexpected error has been detected by HotSpot Virtual Machine:
# EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x21217921, pid=3200, tid=3160

siginfo: ExceptionCode=0xc0000005, writing address 0x034e6360
(plenty more here, I can post the rest if necessary)
The problem seems to be coming from the "return seekStreams" statement in the first file; when I have execution aborted before that (with a fatalError call), it doesn't crash.
Any tips/hints/suggestions?You should write your own Applet, where you can easily get the visual component (getVisualComponent())and show it directly in your Applet (you call it "embedded"). As far as I know, all examples (AVReceive* etc.) use the component which opens a new window.

Hello,
Can I stream video (through WebCam) and audio (through Mic) in Applets?
Can I access the user WebCam from Applet?
ThanksHello,
Can I stream video (through WebCam) and audio (through
Mic) in Applets?
Can I access the user WebCam from Applet?
ThanksTo access the user WebCam from Applet, you can use the Java Twain package http://www.gnome.sk
There is a tutorial with many code examples. One part of the tutorial deals specially with remote applications - there are applet code examples.
On the http://www.gnome.sk there are online examples for the remote applications too - if you have a webcam connected to your computer, the Upload Applet will get an image from your webcam and upload it to the server.

Error Msg Prompted when exit a Video Capture applet
I converted a sample Video Capture App to a applet, when i stoped capturing and exit, this massage prompted:
"The instruction at '0X05a82f30' referernced memory at '0x05aa20f8', The memory could not be 'read'. Click on OK to ternimate the program".
This app will write the captured video file onto local disk, but i've setted the security options in JMF Preference config.
I just wonder why this error message occur?
i'm now working on this applet for my JSP page, i want users can captrue pictures from the WebCam and then save as JPEG images.
I realy appreciate it if any guys can give me some suggestion?I also writing a applet to do that. But I can work in application model. When I run it in browser . It throw out an error. Following is my code....
FrameGrabbingControl fgc = (FrameGrabbingControl) player.getControl("javax.media.control.FrameGrabbingControl");
tt.setText(fgc.toString()+"\r\n");
Buffer buf = fgc.grabFrame();
tt.append(buf.toString()+"\r\n");
BufferToImage btoi = new BufferToImage((VideoFormat)buf.getFormat());
tt.append(btoi.toString()+"\r\n");
java.awt.image.BufferedImage img = (java.awt.image.BufferedImage)btoi.createImage(buf);

Hi all, I wanted to write a code that allows me to capture video from my webcam and show me in the applet window. But the I have seen the webcam being activated but I can't see anything on the screen when I terminate the applet the camera switches of (diactivated). Please tell me the problems with applets? Basically I used a processor to capture the video and used it to produce a data source. I then used a player to play the data source. I have used createrelizedplayer method. If you need the code I will post it.
Thank you.Hi Talha thank you for your prompt response. BTW, I removed all calls to system.exit(0) method and the error code changed. Also I was using the file protocol (file: as FILE:) so after I change everything, the error chnaged. I will post it below. To answer your questions:
-- Which OS are you using? Vista? (then there are little chances that you would succeed) - XP (with SP3)
-- Have you tried running the applet in Applet Viewer? - I tried IE and Firefox (I will try Applet viewer)
-- Are you sure your program is foolproof, i.e. Is is working as Application? - I am sorry I don't get you.
-- You can post your effort at code ( enclose it in tags) - You mean I should post my code. If you mean that I will post it after the erro message.
Thank you again.

If anyone knows how to solve the problems i have, please let me know.
Thank youMHP and OCAP only use JMF 1.0, which does not include support for capturing video. You will not be able to do this in any current MHP/OCAP imlementation that I know of.

Popup fields rendered behind video player applet
Hi,
We are embedding a video player using Windows media player. The code is like:
<object id="MediaPlayer4" width="302"
height="165"
classid="CLSID:22D6f312-B0F6-11D0-94AB-0080C74C7E95"
standby="Loading Windows Media Player components..."
type="application/x-oleobject"
codebase="http://activex.microsoft.com/activex/controls/mplayer/en/nsmp2inf.cab#Version=6,4,7,1112"
style="margin:11.0px;">
<param name="filename"
value="${pageFlowScope.newAssetBean.asset_preview_url}"/>
<param name="Showcontrols" value="True"/>
<param name="autoplay" value="false"/>
<param name="autoStart" value="0"/>
<embed type="application/x-mplayer2"
src="${pageFlowScope.newAssetBean.asset_preview_url}"
width="302" height="165"
autostart="false"></embed>
</object>
Once a popup is shown above this player, the fields in the popup get behind the embedded player.
How do we fix this?Hi,
not knowing your JDeveloper version, there is known bug for 11g R2 --> bug 13492597. It seems that this is fixed in a backport for 11.1.1.6
Frank -
I have a program which captures live video from a video card and puts it on a frame.
When I try to put this in an appplet the sound streams through from the datasource but I can not get the visual aspect to come through.
Are there any issues putting live video into an applet versus putting it into a frame? Are applets capable of
displaying live video?
Thanks
MelissaYou can display visual video components using JMF2.0 (Java Media Framework). You can call getVisualComponent() method of your Player and add it to a Frame on your applet. However the Player has to be realized b4 you can call the getVisualComponent. It's a little tricky, so let me know if you have problems realizing your player. I'm also looking for a Video Player Applet that does not require JMF. So let me know if you find one yourself :)

Web Cam applet is not working in great consistency
Hi... My video capturing applet is not working very well.
The image stream is displayed on the web page in JPEG format with 0.5 quality. However, it crashes after a while and the it does not release the vfw resource.
I have to restart my machine in order to execute it again.
Can anyone please help?
Thanks.
CarterOk. Thanks.

Flash Player linux, grey box issue (youtube vids and some applets do not display)
I posted this question on my distro-specific forum as well as linuxquestions.org, however it appears to be a unique problem, so here it is:
When viewing videos on youtube.com, most other websites, and when trying to run certain flash games, the flash applet will not display (though the audio will play). Instead of displaying the flash applet, there will be a grey box where the flash video or applet would normally be.
This problem occurs on Firefox and Chromium, but not on Opera.
My Specs are as follows:
Distro: PCLinuxOS 2010 (32-bit)
flash-player-plugin: 10.1-2pclos2010
firefox: 3.6.6-1pclos2010
swfdec has never been installed (to my knowledge)
I did a lot of investigating about the problem but have turned up no solutions thus far. Here are my results.
Flash videos and applets which allow access to the settings menu (like youtube played from their website) do not display, however flash videos and applets which do NOT allow access to the settings menu (including youtube videos embedded in other websites) WILL display.
Reinstalling flash-player-plugin and firefox through synaptic does not solve the problem (though note that PCLOS works with rpm files, not deb files. apt4rpm does not support the remove --purge operation, however reinstalls are said to overwrite custom configs with stock ones.)
Creating a new firefox profile and/or starting FFox in safe-mode does not solve the problem
Creating another user and running FFox from that user will properly display flash videos
Comparing default plugins between my main user and new user shows that there is no difference. So this likely rules out a defective extension or plugin binary.
Deleting ~/tmp/plugtmp* folders when FFox is closed does not solve the problem.
Removing the ~/.macromedia and ~/.adobe folders does not solve the problem. (have checked permissions between the new test user and main user, and they are equivalent)
Downloading libflashplayer.so from the Adobe website and copying it to /usr/lib/mozilla/plugins has no effect on the problem.
I'm thinking that there might be somewhere else that flash stores configurations for my user, and that maybe the settings there are corrupted and would need to be purged. However frantic googling has turned up nothing useful so far.
Does anyone have any suggestions for me?The problem, at least in my case, was QtCurve's opacity. If I have opacity set to less than 100%, flash would not display for sites like Youtube and Vimeo, but worked elsewhere.
The solution for me was to go into qtcurve's settings, and put npviewer.bin in the application exceptions section for window and menu opacity. Doing that, I was able to keep my transparent menus, and also use flash everywhere.
You can find out what the application name is by launching your browser of choice in a terminal with qtcurve debug turned on, like so:
QTCURVE_DEBUG=1 firefox
If you watch through the lines that start with "QtCurve" you'll see "Application name". Look for the one that shows up when you try to load a video. In my case it was npviewer.bin. In yours, it might be nspluginviewer or something else. If you add an exception for that specific application, you'll fix your problem without having to compromise on your theme. -
Hi
I have created a video to put on my websites home page.
However, when I try to insert it using Dreamweaver it doesn't play.
In dreamweaver which is the best option to insert a video?:-
Insert flash,
flash video - progressive download video or streaming video
shockwave,
applet,
active x or
plugin.
And is there any particular format I need the video to be in?
Thanks for your help,

FLV/SWF is well supported by most browsers & systems.
It's the file type
used on YouTube, Google Video and MySpace.
