Live Video in an Applet

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
Melissa

You 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 :)

Live Video Broadcasting over LAN

Hi Guys,
I have studied the JMF Framework.
And sucessfully transmitted and received video and audio over a network i.e. LAN.
Also I have successful in displaying Webcam onto applet.
Only issue with me is how do I broadcast the Live Video to clients.
Do help me at the earliest.
Thanks and Regards,

Ummm, the same way you broadcast a video file.
You feed the DataSource associated with your web cam through a Processor, program the Processor's tracks to output the encoding you want, and then you send that out via RTP.
And on the receiving end, nothing changes from the video file.

Stream live video in internet explorer.

hallo
To stream the live video from webcam in internet explorer in system ( as server) and then sending that output to the (PPC) Pocket PC ( as client ) . in the
PPC also video should stream in internet explorer.
plz suggest me some valuable procedures. any person had tried or done this ,plz send me the sample code.
Very Urgent
thanx.

Hi...
I wanna know if you did it. I'm a studant and I have some interests to learn how can I show a streaming video through internet.
A couple weeks ago I did two applications make message exchanges by sockets.. I think is something like this. But I wanna know how to get de webcam image and transform it in a stream of bytes to send it to another application.. so the socket server must pass that bytes to the applet in Internet Explorer... I think so... xD
C ya.

How to display live video captured by a webcam on another computer?

I am now writing a program to display live video captured by a webcam on another computer which is in the same network and I need to make it display on a applet page.
I have already figured out how to capture live video on my own computer and display it on applet.(thank for people in Java forum). But for a webcam which located on another computer in the same network,what should I do? what technique do I need to achieve that?
can anyone help me?
Thank you very much

Hi AbSoiLoki,
Thank you for your reply. I have been able to locate a couple of different options here for you to try. There is a previous post for a different printer that is having the same issue with the printer mapping a Z:folder.
The link here will direct you to a post on the HP Forums with some trouble shooting steps for you to try. Click Here.
I have also included another document on How to stop printers from grabbing drive letters, Click Here,
Please let me know if this has been able to help you resolve the issue.

I am new and need help --- Streaming live video

Hello,
I am attempting to stream live video from my Trendnet TV-IP 201 cameras through my web site. We have been able to embed the xplug.class applet into the page, but we can not remove the controls. If someone has any knowledge on this, please help us out. Thanks in advance for the help.

I have the same problem, need to show and capture the video from Trendnet IP-camera and the same xplug.jar that sits in the camera is decompiled here:

Mid 2011 mbp i7 with a SSD has problems, including grey screen/blue screen/beeping/freezing when I stream live video (i.e. watch espn or time warner cable) Help? Ideas?

Recently my Macbook Pro (June 2011, i7, 8gb RAM, 512gb SSD, AMD Radeon 6750, Mountain Lion - since July - currently 10.8.2) has been presenting me with an array of problems, usually initiated when I am streaming live video. I was streaming Time Warner Cable on 12/9 and it gave me what looked like the blue screen of death. It started up after about five attempts that time. The other day, after about a week of not using the computer, it wouldn't boot past the grey screen. I (option) started it and it gave me two boot choices, the regular HD and a "10.8 restore" option. The HD gave me the grey screen and the restore option gave me the dark blue screen. I reset PRAM and that didn't work. After a force (x) start it worked. Today, I was using "Watch ESPN" and the screen froze and the computer did some kind of repeating RAM beep or something. I rebooted and it started up fine. I'm not watching any videos anymore, but this is a problem since the primary purpose for my mbp is video editing. I'm still under AppleCare but I find more solid answers in the forums or at least better questions for the AppleCare people.
Anybody have similar experiences, or a solid idea of what the heck has happened to my machine?

I'm not really sure what method that person was talking about. I just read he had a successful install so I posted it.
But I'll hazard a guess
1. copy your entire drive to a backup drive
2. boot into that drive and test it out - make sure its a flawless backup, it works, and the hard drive has no problems
3. eject that drive, disconnect it and reboot into the leopard install dvd
4. erase your main hard drive using disc utilities on the leopard install dvd -- you've made a backup, made sure that backup was good, and disconnected it so it's currently safely disconnected from the leopard install you're about to do. Also, on the hard drive you're erasing and installing leopard on to, many people recommend "Zeroing" it as well as erasing it. That option is part of the erase function in disc utilities on the leopard install disc.
5. do a clean install of leopard
6. follow step 4 from that original post exactly as that person described to do.
7. read the rest of what they said
That's pretty much it. With the backup/erase/clean install/import/ you pretty much get everything you need exactly the way you want it with very few things missing -- and you've done this over a clean install. Plus that poster did mention that you can select what you want to import from your backup hard drive.
It sounds like its a "clean install" method that gives you control via "import from machine" option in the installer. Control over what parts of your "old mac" you want to import into your "new leopard mac".
Hopefully that helps. It sounds more involved, but its actually pretty quick and provides you with a perfectly save backup in case anything goes wrong with the leopard install.

Can I connect an external video camera to a mac book pro for viewing live video so I don't have to use the little screen on the camera?

• Only if your video camera supports it. Depending on how your camera works, you may need to add preview software to your Mac to use this feature.
• Alternatively, your camera may also be able to record directly into your Mac while you are monitoring the Mac's display.
• If you are using a consumer camcorder that supports HDMI monitoring, a small HDTV might be an simpler solution than your Mac. For an example of how this is done, see http://youtu.be/GVpSkZD6qE4.
• The retailer who sold you your video camera may have other suggestions.
• If you need more professional results, an external preview monitor will offer more capability on compatible cameras.

Is there a way to use Illustrator to draw over a live video feed coming from my microscope?

Hi, we use illustrator to draw (trace) over static images of mite specimens taken under a microscope. Although this works, it would be much better to be able to draw directly from the live video feed coming from my microscope. The specimens are dead, so they are not moving around, however, we need to focus down through the specimen in order to see all details. We normally take montage images, but because the specimens are clear there are many artifacts present and we frequently have to consult the specimen under the microscope to double check things. My students and I have hundreds of drawings to complete and are looking for a way to streamline the process. If we could avoid making montage images and draw direct from the video feed, it would revolutionize the way we approach our research. Is there a way to display the video feed and then overlay Illustrator so that we can directly trace over the image (we use a Wacom tablet, but that shouldn't make a difference) so we can focus at different levels and draw the entire organism?
Thanks for your help
Ashley

Maybe it's possible to have live video in Illustrator, but you would most certainly need to write your own plugin.
So this community would be suitable:

What are the requirements to build a live video chat application?

I am looking into making a live video chat application. I
have seen several examples on the web so my question is not "how"
to do it. My question is "what do I need" to do it?
It seems that all the examples use Flex Data Services and
then some sort of back-end communication server. The cost of FDS is
well beyond what the client can afford so my question is: is it
necessary? Is there a way to build this sort of application without
FDS? Can I get live video streaming to work using only what is in
the SDK? I know nothing about data streaming, real-time
communication, etc. and have no idea how to implement this outside
what I have seen in the online articles so far.
If there are any other forums that are more appropriate to
this question, please direct me there. It is not a FDS exclusive
issue and I am just starting to look into it. I am starting here
because we would like to use Flash Player for the client-side
application.
