Java :: Make A P2P Streaming Using Web Browser?
Aug 13, 2010
I want to create an application for P2P video transmission. In more details, I need the following:
-User can switch on a web camera by clicking a button in an application.
-Application starts to take images from the web camera and sends them to a certain location (given by a port and IP address).
-Application starts to accept images send by another application and display them (images) in a window.
I would prefer to have everything in a browser. I know that everything can be done with Flash Player from Adobe (an example is Url...But I would like to know if the same can be done with JavaScripts.I am sure it the application can be written in Java. But can I use Java to have everything in a Browser.

To clarify when I ask about browser to browser communication I mean without a server in between forwarding message. I would like to implement something like this for a game. If p2p in websockets isn't possible are there similar alternatives?

I herd about RED5, but unfortunately I can't find any examples for feeding it with external source. I know RTSP is in development, but I'm thinking about (named) pipes or something like this. There is is also project named xuggle that is as far as I understand ffmpeg wrapper for Java, but I herd they have also problems with live streaming.

I'm getting to work with with red5 and am trying to make a basic app that will stream a random video to the client. Let's say I have 3 flvs on my server, I'd like a client to connect to my red5 app and have 1 of these 3 videos streamed to them. The only streaming i've been able to figure out so far uses netStream.play("video.flv"), this doesn't work for me, I want the server to decide on the file to stream rather than the client.

Has anyone used or is aware of a service browser to test AMF calls?I am looking for a tool similar to ZamfBrowser ( http:[url].... ), but one that works for the Java environment.ZamfBrowser is geared towards AMFPHP.The idea here is to provide a service browser, that allows developers to test Java services using the AMF protocol, without having to go through the Flex UI all the time. There has got to be something out there already for this, but I can't seem to locate anything..... It's kind of funny and strange that a service browser exists for AMFPHP but not for regular AMF calls in a Java environment.
I would imagine something exists under Blaze or LCDS? ...Trying to find it in the docs but can't seem to find anything ....The best alternative I can think of at the moment is to use FlexMonkey to record stuff, and then to simulate it using that....which is okay I guess but still sucks because you have to go in and create the Flex UI first, whereas with something like ZamfBrowser, you simply point it at the service calls,it tells the server-side developers if their code works, etc. generates the required as3 classes for you... and makes the integration process much easier in a large team.

My client needs to let a user record a message from the browser, then export the message as an audio file (e.g., WAV).How is this best accomplished? Flash, Java, HTML5? By best, I mean something that is straightforward to implement and also broadly supported.

I followed this tutorial [URL] put the proper actions on my button, the button calls the window in a blank page but it does not have the settings in the javascript no scroll, no resize and a preset window size.
The tut is from Flash 5 and that was before the "ACruncontent" file flash uses now in cs3. window opening the way I need it is critical for a client.

I have a small application to play a stream from an Internet radio broadcast. When I play the .swf locally it has no problem at all, but once I put the swf on the browser, nothing plays. I don't know if is a security issue. The path to the stream file is in another domain of the page I am mounting it, for example, I put my html file on: w w w . myradio.com/index.html and the swf is calling [URL]

I'm recording a mono audio stream using a PIC at 8-bit 8Khz and streaming it raw to another microprocessor that houses a web server.I'm currently buffering the data and turning it into a wav file that gets played in the browser.What I'd like to be able to do is continuously stream the audio as it's being recorded without putting a lot of encoding overhead on the second processor.I've been searching but most searches turn up just streaming from a stored file, but since the file size isn't known ahead of time I'm not sure how to do this without the overhead of mp3 encoding.

I would like to execute a cross domain http request from a website. Javascript is out, because most browser don't allow cross domain calls. Generally the solution is to use a proxy, but that isn't an option for this project. The other things I was thinking about would be to use Flash or maybe Java. Are there any other platforms that I could use?

I would like to know if it's possible to edit a file from within the browser. I know where the file is and I know its format. I would like to some HTML5 and JavaScript but have little luck so don't mind using Flash or Java.
The file I would like to edit is the hosts file. C:WINDOWSsystem32driversetchosts on Windows XP.
This is mostly for test run of a new breed of AdBlocking so would like to give my browser and the best chance of working. I have Google Chrome Dev opened as ROOT, running on Windows XP.

How do I download multiple files at once from a browser without combining them into single file? I found all kinds of multiple file uploaders, but downloaders are missing. There is only JUpload, but it's old and became buggy recently. I believe both Java and Flash can do this: select a folder at client's HD and download everything there.

We're designing an application and the client has requested that a portion of their app stay in Java Web Start and another portion be in a browser. I'm thinking about AIR as an alternative to the browser because that may give us more features b/c we don't have to stay in the browser security sandbox.How would I go about having an Air app talk to a Java Web Start app? Do they have to talk through a server? I guess potentially you can just create a socket connection between the two.

It goes like this, we need to detect if the display is a Projector (or if the system is connected to a Projetor).the catch is this should be done from within the browser.so is it possible to do so by using anFlashActiveX (this does constrains to a single browser, so not an option)searching so far only reaveals display resolution. expecting if there is something still out there.

I'm going to do a voice recording plugin/addon on a website that will record audio and send it to the server for further processing. I have had two suggestions; either write a java applet or use flash. The service is supposed to work for all major browsers(IE, Firefox, chrome,..). I'm new to this area of development and is looking for tips on how to proceed with this. What is the pro's and con's for each solution?
For java applet, what Java speech API library do you recommend? I want a simple, small library, I only need voice input. Also, I am puzzled by Flash development, I can't find any good information about development, the adobe website dosn't make much sense. What is the programming language for flash, and how do you actually run it in html code? I have found ActionScript 3, is that used to create Flash plugins and can it perform voice recording?

in other words, suppose I want to send data, like text, programmatically from a Windows app (such as a browser plugin) to a Flash app running in the browser. Well, conceptually, an example of this might be a Flash instant messenger with a textbox and button "Send"; so let's say I want to be able to programmatically paste the text and press Send or otherwise activate it. That's NOT what I am trying to do here in reality (i.e., no,I am not trying to spam other people's chat rooms or anything)but just an illustration of a similar situation.I can include in it whatever widget or hack that may be necessary.The reason why this problem is arising for me is that AFAIK the SDK that is providing me the data I want cannot be directly accessed from Flash, so I need a way to pipe the data from a regular app into Flash. can I have the Flash app interact with other apps through localhost IP? Or are there draconian restrictions on which server Flash in browser can and cannot interact?

What I want to do is have control over the streams so I can send them wherever I want, have it interface w/a mic and cam, and the ability to capture and record them. At this point I don't have any specific specs or limitations. It will be used in a commercial project so the license must allow for that. Free and OSS is preferably, but commercial and proprietary is not out of the question if it's worth it.
I don't see html5 as a viable solution at this point so I'm assuming it's going to rely on flash which is fine, but I do not know actionscript. I'm not opposed to learning it, and assume I could pick it up fine within a week, but keep that in mind. If I have to build something myself from the actionscript libraries (I assume they provide enough functionality) I can do so, but I'm hoping for a quicker solution than that.

What is the best (and simplest!) way to record video from a webcam to the local filesystem--all from a browser? Ideally the video would be recorded in HD and then we could use ffmpeg later to convert it into the formats and sizes needed.
Here are some things we've looked into:
Use Flash to stream to a local Red5 server. But we've had issues with video quality here. A Java applet using JMF (can we even write to the filesystem from an applet?). We've heard this might not be very efficient though. Can it handle HD?
Write a custom Firefox plugin. Would this be very difficult?
Basically the hardest thing here is that the controls need to be embeddable into a browser. All we need is a box where the webcam frame is displayed to the user, and then some Javascript hooks so we can code start/stop buttons within the HTML page.
The computer is fully controlled (it's a kiosk) and we can do just about anything to it. We just need a solution that runs in the browser. Our current app is run in Firefox in kiosk mode and the webcam recording is just a part.

I've been trying to understand how flash animations or a Java Applet work within a browser. I can think of a couple of ways - The Flash Player/Java Applet are machine code that's dynamically linked it, and given some parameters about the area of the screen that belongs to them; after that, they run within the same process space. The browser exposes an API that the player/applet use to talk to it and they live in a separate process. (Presumably they talk via sockets?) The API could correspond to openGL/X11/some custom calls.
These possibilities still don't explain things like how a button click can make the player full-screen, how it can play music, how it can inspect the DOM, etc. For that matter, is the video displayed by decoding to a sequence of images, and rendering them one at a time, or is there a more efficient way, e.g., of pushing the deltas in the image? The Wikipedia page on Java Applets
(1) talks about how the applet is run in a sandbox (presumably a separate process), but it doesn't say how the browser and the applet communicate. Perhaps the answer depends on the underlying platform?
