Broadcast live video

I just bought a MBP 15" 2.0 i7. i would like to do live broadcasts of high school sporting events. I need to know a program to use and which Sony camcorder would work best for this. Nex-VG10 or HDR-AX200. What type of cables or connections to use as well. i would be using wireless internet provided by the school.

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.

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.

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?

Broadcast, live stream?

Hello. I have a few questions regarding broadcasting live video streams in H.264 encoded format. I am new here and have little knowledge about the topic. What I am interested in is how can I broadcast (multicast?) live video streams over the internet to multiple viewers? I have video content on a HDD, encoded in H.264 which is constantly updating (I add new files, remove old ones and so on, kind of like a TV channel or Internet Radio but with video), I need to feed that content to a live stream server somehow. It should not be an "On Demand" stream, but "live". What software do I need for this? What do I need to broadcast my so-called "live TV" to end users and what software should I use to auto "feed" the server with new content? If you have any thoughts or can give me links to helpful resources I would appreciate it a lot! Thank you!

I already took a look at that software. I don't sure if it fits my needs. Lets say I have a video source which is an uncompressed live stream. I need: to capture that stream, compress it using H.264 encoding, then rebroadcast it. The time buffer I have is 8 hours (I can broadcast the compressed stream after 8 hours after getting the original stream). Now, how do I do it?

Live Video Broadcasting

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,

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.

How to deinterlace live video using flash as a broadcaster?

I am trying to replicate the deinterlace functionality that is available in FMLE in a simple flash broadcaster that is hosted on my website.
I have built a flash broadcaster (using Flash CS4 and AS2) that connects to my FMS server with the aim that people can stream live video to the site. That all works OK; however, I would like to be able to implement a deinterlace option like that which is available in FMLE. Any clues?

go here: http://www.progettosinergia.com/flashvideo/flashvideoblog2005.htm and scroll until you see the blog entry from the 26th of September.
There is no direct link to the post.. But the solution he provdes should do the trick.

Does anyone know a work around to broadcast live (in real time) via video stream through a BC website?
~Leritha

There is no work around. You would look to use a service, like Twitch, you get a embed code for the live stream, you put that on a page and away you go. All depends on the service your using.

How do you stream a live video to a website

OK - Again I'm feeling smart enough to be real dumb.
How do you stream a live video to a website. I use GoDaddy to host a website. I can plug a video camera into my Mac so I can run the video through whatever program works best. I even have a .mac account (now its mobile me I guess) and could use that. I have read several threads but can't really find a starting point. Any help is appreciated.

How do I stream live video on my website or via Quick Time?

Okay, so I've searched these discussions and have found many people with the same question going unanswered.
Basically. Our dog is at home, just out from surgery and we want to keep an eye on him from work.
I've downloaded Quick Time Broadcaster to our MacBook and am using the built in iSight camera on it. I am able to broadcast via the application "Quick Time Broadcaster" and have been able to view the live video stream through Quick Time player from a second computer in our home. But I am unable to view the video at work using the same URL generated from QT Broadcaster. Maybe it's a firewall issue?
But more so... I'd like to embed the stream into my personal website. What do I need to do to set that up? I've also downloaded and setup Darwin Streaming Server, but it doesn't make much sense to me at this stage in time as to how to get that running and linked up through my personal web site. Anyone know how to set that up? So I can do something like www.mysitename.com/petcam
I'd like to be able to view the video via the web using an address similar to something like that, but via my personal web domain.
Worse case... I'd like to at least be able to watch the stream via Quick Time player from work... like I can from home. Any work arounds or steps I'm missing so I can view this at home? Any help is greatly appreciated.
Many Thanks

Thanks for the link... lots of good stuff in there.
I did read about EvoCam in another thread here. I was hoping it would of been as easy as writting some code into an HTML doc and uploading it to my webserver with the proper IP link. Guess it's not quite that simple... or complicated. I was also hoping to be cheap and not have to buy anything. The price of EvoCam at $25 bucks isn't so bad. I'll look into it when I get home this evening. There were also a few other applications at that link that seem to do the same thing. Wondering if they'll all give me the same results? Or is EvoCam the cure all with the best results and options...?
Thanks for the input. Any further suggestions or comments are greatly appreciated.

Live Video Plays Locally But Remotely Only Skin Is Visible

Hi Guys,
I have tested other embedded videos and they will play remotely so I know the hosting site is working.   Can anyone please look and tell me what I can try to make the vid work?   Currently, the live video will play locally and remotely from this computer where all the files are stored but only the skin is visible on any other remote computer's web browser.
I will post any info you ask for.   I have been working on this forever.   Please, someone who is good at this help me?
Here are my files look (I can't figure out how to blow this up larger - can you see it?):
I will try whatever you suggest.

The Adobe Dreamweaver Tech Support said to post here and that the Expertise Team (you I suppose) would figure it out. I am running Windows 7 64-bit OS.
My live video is being broadcast by Adobe Flash Media Encoder to Adobe Flash Media Server 4 and inserted into Dreamweaver. Dreamweaver Support watched me re-create the Flash file and import into Dreamweaver and we looked at it for hours together. In the end, they suggested I post here because we could not figure it out / it is not supported. Ideas?   Can I provide any other helpful info?

Most likely it's a URL problem. What the player is looking for is the remote URL to the server... not "localhost" or some other address on your local machine.
So when you config the Adobe Flash Media Live Encoder, there is a dialog box asking for FMS URL:
Your remote URL will look something like this:
rtmp://76.192.182.133/my_streamer
where the protocol is rtmp, the Web address is the address of your host server and the name of the application you are using to do the streaming is the last part of the address.
Of course this means that you will need to have an application already residing on the server, it's not enough to just have access to a Flash Media Server, you also need an application to do the streaming.
The next important part is to give your stream a name, it can be whatever, but this name will be used on the Web page.
something like:
Stream: test_stream
With those settings, here is what a Web page would look like:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<script type="text/javascript" src="swfobject.js"></script>
<title>Streaming Test</title>
</head>
<body>
<div id='mediaspace'>
<script type='text/javascript'>
    var so = new SWFObject('player_new.swf','mpl','500','410','9');
    so.addParam('allowfullscreen','true');
    so.addParam('allowscriptaccess','always');
    so.addParam('wmode','opaque');
    so.addVariable('image','live_intro.jpg');
    so.addVariable('file','test_stream');
    so.addVariable('bufferlength','10');
    so.addVariable('streamer','rtmp://76.192.182.133/my_streamer');
    so.write('mediaspace');
</script>
</div>
</body>
</html>
that's the entire page, just copy and paste into a new html doc in code view.
See where the variable 'file' is the name of your stream 'test_stream'
And the variable 'streamer' is the URL of your host FMS with the application name at the end of the address.
This is working code from the JW Player using swfobject 1.5 (notice the call to swfobject in the <head>).
There is also an image (make it 500 x 410 or whatever size you set your player to) that sits in front of the player until someone click the play button.
So to make this work, you need 3 files, the JW Player itself, the swfobject file, and a thumbnail for before the Live streaming starts.
You can download them all here from my site:
http://www.cidigitalmedia.com/tutorials/streaming/player_new.swfswf
I changed the file extension to .swfswf so that you can download and not have the browser open the .swf. Once you have the file, change the file extension to just .swf
http://www.cidigitalmedia.com/tutorials/streaming/swfobject.js
swfobject for Flash detection, also great for adding alternate content for non-Flash browsers.... but that's another story.
and an image here:
http://www.cidigitalmedia.com/tutorials/streaming/live_intro.jpg
download to your screen and right click and "Save Image.
Put all the files in the same folder as your new HTML Web page.
Change the FMS URL to your host URL.... I'll include a photo here:
http://www.cidigitalmedia.com/tutorials/streaming/streaming.jpg
That is where your URL info goes. When you click the "Connect" button, you should get a message in the "Encoding Log" tab that tells you whether the connection was successful of not.
For more info on the Adobe Flash Media Live Encoder:
http://forums.adobe.com/community/flash/flash_media_live_encoder
You now have everything needed to properly display a Live stream... provided that is that your FMS is correctly set up and that you actually have a working, streaming application installed on the server.
One more thing:
"I even tested another embedded video just to make sure the host wasn't the issue and that video played live perfectly even remotely but my feed would not."
A Live feed is completely different from prerecorded videos. It uses a different protocol, Player configuration is different, and of course you need an actual application that streams Live video.
Best of luck! I hope you can get this going!

Live video feed using Flex/Flash

Hi,
I have a question if someone doesn't mind giving me a "yes"
or "no" answer, please.
My developers have created a program for me that lets me
broadcast my LIVE web cam feed right on my web site in real time so
I can provide customer support and allow me to engage with web site
visitors. We are using Flash, Flex, and Adobe AIR.
The broadcast window size is 320 x 240 pixels. The problem is
the frame rate. I am only able to broadcast between 5 - 9 frames
per second whereas other people have been able to broadcast at
around 14 FPS.
Question: is it possible to use these applications
(Flash/Flex/Adobe AIR) to stream live video at 320 X 240 at frame
rates at least 24 or higher?
Thanks in advance for an answer. I don't expect a solution.
Just a yes or no from some experience(d) developer(s).
All the best.
Rodney

Lucas,
Here's what I do for multi-camera live shoots:
1. Connect all cameras to a switcher/DVE (looped through preview monitors) - I use a Panasonic WJ-MX50 or Sony DFS-300 Since you have five cameras, you'll obviously need a switcher with more inputs, or gang two of the above together. You'll need a switcher capable of the signal output your cameras offer, ie: composite, Y/C, component, triax .. whatever.
2a. Output of switcher goes to DVCam VTR.
2b. Audio is fed through a mixer and output to the VTR.
3. Firewire out from the VTR to the Mac/FCP.
4. In FCP, choose "Non-Controllable Device" and use Capture Now.
5. Use one of the analog outputs from the VTR to feed the projector(s) and the another analog output to a program monitor for the TD.
I always run safety tapes in each camera while the VTR is recording a switched master tape in case there's a problem with the capture in FCP (it can happen).
I also equip each cam-op with a 8" or 9" monitor, typically using the camera's composite output. And everyone is able to communicate using a Clear-Com system.
In 5 years, doing several shows per year, the capture in FCP has only failed three times and all of those times were when I was using a laptop. Whenever I've used my old G4 tower, capturing to one of the internal drives, its worked flawlessly each time. Fortunately, having a Master DVCam tape saved the day. The camera safety tapes are used just in case of a bad switch by the TD (usually me).
-DH
PS I should add that if you're feeding multiple projectors, you'll need a simple DA.

Streaming Live Video to I-Phone

Are there specifications for streaming live video to I-Phones?
I work for a webcasting co. and we would like to offer our webcasts to our clients via their cell phones. I haven't been able to find any documentation relative to live video streaming to an I-Phone.

Hi,
Since the iPhone browser can play MPEG-4 movies, it should be able to play streamed MPEG-4. Flash and Windows Media isn't an option.
Fortunately QuickTime Broadcaster is free, but you'd need a QuickTime Streaming Server to "bounce" the stream off. Setup Broadcaster to do an MPEG-4 video that's within the playable specs (given that it's a live stream, you'd want something as small as possible, so I'm sure the iPhone could handle it). If you're wanting your clients to access the stream over 3G as well as WiFi then you'd need to keep that in mind when determining the video size/bandwidth.
