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.

I want to do a project on video conferencing over LAN .Plz help me
for implementation.Have you tried AVTransmit2 and AVReceive2 to transmit multicast stream. then have multiple receivers join and disconnect.
It works without any code modification, so I would study the differences between that and yours.
I think I asked this before, are you transmitting multisession?? and receive multisession??
Are you using linux by chance? -
We have a quarterly Town Hall event we set-up. We have an audience of about 100 employees at our local corporate office. We would like to broadcast a live video stream of the presenters as well as have the presentation available on the screen. We have another 100+ employees that watch this over the web.
We've been using WebEx Training Center for this, but it's limited in the camera and audio options, and a webcam is just not cutting it anymore.
I want to preface that I'm a PC guy, but we're slowly adopting Apple technology into our company (15 iPhones, 60+ iPads, some MacPro servers for designers, and a couple of MacMinis and MacBooks for testing).
I've done some research and see that Quicktime Broadcaster might be what we're looking for, but I'm hoping the community might be able to help us figure out exactly what we might need.
We'd like the production and end-user experience to be very similar to the Apple Keynote that they do at WWDC every year, but simpler.
HD Video Camera - We only need 1 Camera Angle, however we want the ability to zoom, get HD quality, and have it be a non-web cam, Professional camera.
Audio - We need this for the live stream, recording of the event, and then local amplification for the audience
Lighting - I don't know a ton about this, but we would need some lighting for the presenters to "look better" on the feed.
Teleprompter - We don't need these so people can read from them, but rather we need them to display a timer so the presenters don't go over their alloted presentation time. We frequently go 20-30 mins over our scheduled times.
Presentation - We have a PowerPoint deck that would need to be presented along with the video feed.
Other devices - Occassionally, we'll need to connect an Apple TV to display something from an ipad, etc. and we'll want that to be streamed as well.
That's it in a nutshell. I'm an AV geek, and have had a lot of experience setting up basic video productions in the past. I've used various apps like Finalcut, Sony Vegas, etc. to do post production, but never any software for live broadcast stuff.
I'm thinking it might be better to get a consultant in here to help us set up a system, but if my team of 7 can do it ourselves, we'd rather.
Any help you can offer would be great. I'm open to using Apple technology obviously, which is why I'm posting here. And if anyone knows how Apple does their live WWDC Keynote streaming, that would be a great benchmark to use.
Thanks,
David Jackson

Hi,
I was wondering how to write an application that does a broadcasts over a local network.
The idea is one program that does a broadcast over a lan, and the clients respond to that broadcast. Only things I find are MulticastSocket's and similar, but no real broadcast examples.
Any suggestions?The only difference between multicast and broadcast packets are the network you use. A multicast is in the 224+.*.*.* range and a broadcast is typically limited to the network the server is on e.g. 10.10.10.*

H.323 video QOS over LAN to LAN
I need to configure QOS for video over gig fiber LAN(4506 catalyst switch) to LAN(3500 switch)
Many IP video conference applications use the H.323 suite of protocols. The International Telecommunications Union (ITU) H.323 defines an international standard for multimedia over IP. Refer URL

I am working on a program that broadcasts a packet over the LAN.I implemented a datagram packet which has some data inside .Is there any way to broadcast this message to the computers without specifying the port number..I want all the computers on LAN to take this packet
here is the part of the code.
DatagramSocket socket = new DatagramSocket();
InetAddress address=InetAddress.getByName("255.255.255.255");
DatagramPacket sendPacket =new DatagramPacket(m,m.length,address,?????);
socket.send(sendPacket);Hi!
as far as i know you have to set a port number ;) so:
int port = 2000;
DatagramSocket socket = new DatagramSocket(port);
hmm... getByName is not a good idea, try getByAddress, defining a byteArray first (255,255,255,255).
InetAddress address=InetAddress.getByAddress(yourByteArray);
Define your sendPacket like thist, where "buf" is the byteArray of your sendData, like:
buf = sendData.getBytes();
DatagramPacket sendPacket =new DatagramPacket(buf, buf.length, address, port);
finally:
socket.send(sendPacket);
could work...

Live video conference over internet
hi frndz,
i have done a video conference application which works fine in LAN.
i have a static IP server to host the video conference application.
my problem is that i was not able to recieve the video transmitted from the server. in vise-versa if i send it from client which is in different network, i am able to recieve it frm the server using the public IP of my ISP,
can any one help me how to transmit in rtp:// from server and how to recieve it in the client side
i have checked this transimission and receiving by JMF studio and my code
rgds
-venkathi,
first get clear idea on JMF archietecture and wot it does,
Start with creating a player,
learn about processors, DataSource, realizing a player, media types supported by JMF and RTP protocol,
by learning above things u ll be clear about how to start ur video conference app,
for further clarification revert me back

Hi,
I would like to set up video conferencing for our company. Ideally we are looking for the ability for internal users to use CUVA with their IP Phones (which they can currently do), with the ability for other companies to also connect - I'm guessing through a gateway device. Multiparty conferences are required. We also have a few Tandberg H.323 devices in meeting rooms which would be good to be included. What would be required for this setup? Is a Cisco Unified Videoconferencing 3515 Multipoint Control Unit (MCU) all that is required or is there additional requirements? Your thoughts, etc would be appreciated.bandwidth should be at least 384k or 512k

Have just started using my new Macbook. When I try to view live video broadcast (eg live snooker from the BBC) it is very jumpy and jerky. This happens using both Safari and Firefox. It is not the line speed as it is fine on my old PC. Non live video works OK. Am I missing some software? any ideas?
Hey archaeo1,
I would love to see a solution your problem, because i have exactly the same issue, with anything live from the BBC website. I have tested on Firefox, Opera, and Safari, and have found them all to be jumpy despite having updated flash. For the first time my step father has embarrassed me with his flawless play with Internet Explorer on his Windows 7 PC.
Have you found a solution since you posted this in Dec? I would love to know if you have! -
Adobe Flash Reversed to Broadcast Live Video without a Webcam
This is all true and is happening now.
I had heard that someone had taken Adobe Flash to new limits, albeit surreptitiously, was able to remotely activate your webcam without indicator lights revealing the clandestine activity. I unashamedly hold an objection to the commercial use of personal and private information to gain revenue via direct marketing or by on selling said information and an even greater objection to government agencies collecting and using personal and private information to build dossiers on the very same citizens that governments are elected to protect and serve for the purpose of political influence, persuasion, terror or torture. The only thing worse than either of these two scenarios is tendered government contracts for the collection of personal and private data or buying directly from a commercial entity that have collected data on individuals.
When I heard that remote activation of a webcam was possible, I took measures to counter this threat by personally managing the Flash settings in the web browser, ensuring the browser settings always matched the Adobe Flash settings for use in Google Chrome, either by selecting "ask before allowing website to access camera" or outright "deny access to camera" and deleting the "exceptions" for that particular website or all sites. To be absolutely certain of my privacy I added the auld low tech safety net which I was certain could not fail, a strip of gaffer or "duck" tape over the lens of the webcam. Occasionally I would also turn the inbuilt mic off for added piece of mind. I thought myself that perhaps I was being a little paranoid until recently when I began to suspect that I was being observed when I would enter a chat room. A look of surprise or a generous smile from the host would greet me upon my arrival, priding myself in the most basic of social etiquettes, good manners, I would always respond with a nod or returning the gesture in kind. However, this is where I became confused because the hosts were always reluctant to confirm this was happening when asked directly, or made an effort not to acknowledge my presence again, which in my eyes, is an admission of guilt.
When I put my laptop to sleep by closing the lid evening last, the unusual and rare combination of hardware and software failure occurred activating the log on screen on the external monitor. Secure in the knowledge that the lid of the laptop was closed, a piece of black gaffer tape adhered to the webcam, I knew I would not get a better opportunity to prove my suspicion that Adobe Flash has been re-coded to not only play live video but to capture and broadcast it as well. I entered the chat room and sure enough an acknowledgement from the host was immediately forthcoming. A moment of divine intervention allowed a conversation to evolve where upon I revealed that my webcam had been disabled and my monitor was acting as the only capture device. Having now confirmed my suspicion that my monitor, not the webcam was broadcasting video, I set about collecting additional evidence and to make the case rock solid, enlisted an independent witness at my end to find on this verdict beyond reasonable doubt.
My unsupported theory is that, if this technology has indeed been developed legitimately, it has been done so for the purpose of Windows 8, because although this computer is running Win7 Pro it originally came with Windows 8 but as I had ordered the computer with Windows 7 Pro, I sent it back to HP and they returned it with Windows 7 installed. I have been informed by my I.T guy that Windows 8 has new hardware configurations that are specifically designed for the Win 8 platform.

Q 1.:
Is this the way things are going and do I need to contact my mask maker?
Q 2.:\
having now switched back to Mozilla Firefox, will my secrets be safe again once more ?
Q 3.:
Does Adobe condone this technology and if it does, why has there been no information released about it?
Q 4.:
If we do have to live with the entire world watching, where is the off switch?Yeah... I smell a hoax intended to instill fear then.
Something silly, such as this page:

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
AshleyMaybe 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:
