It somehow should be possible to get all data from Flash File that running currently in browser.
Get all data from rendered objects like values, positions and ect. The more inforamation the better
So what I think is if my computer my adobe flash render all this locally so I'm receiving already it to my computer so I need to read as adobe flash render this.
Look at how Scout works (some info here)
It opens a TCP/IP telemetry channel from which it receives all informations about the movie playing.
I suppose the data would be pretty hard to figure out, plus the movie would have to have the telemetry feature enabled ... but it's a start

I've spent plenty of time solving this problem, but it looks like I need some help. I have a web conference application which provides ability to stream live video, chat, share documents, draw on a whiteboard, share desktop, etc. And now I want to record everything that happens in taken separately so called webinar, including video and sound. So I'm looking for tools that can help with this goal.
Here's input data:
This is Adobe Flash based application
Using wowza server
Everything should be recorded on server
Many webinars can be in recording mode at the same time
Record should be represented in video (flv, mp4 or whatever)
What I've done so far and what I problems I have:
I have implemented recording on server side. But this is not a video, this is just a list of commands to recreate passed webinar. It works, but has lot's of limitations and problems with rewinding.
And now I'm testing this FLV Encoding library. I created AIR application that starts on server when record is needed, connects to taken webinar and takes screenshots from itself with BitmapData.draw() method. Works pretty neat, but has some limitation that I'm looking help with:
First of all, this is sound problem. I have no idea how to catch all
sounds from all sources in flash. So far from my tests and googling I conclude that SoundMixer.computeSpectrum() won't help me to do this. Maybe this can be done on server side by mixing all streams on the right time but I think this can lead to synchronization problems and I prefer to capture sound on client. Maybe there is way to capture audio byte array from rtmp stream somehow?
Security problems. We have 2 kinds of them. First ones are with streaming videos. BitmapData.draw() method throws exeptions even after adding <StreamAudioSampleAccess>true</StreamAudioSampleAccess>
<StreamVideoSampleAccess>true</StreamVideoSampleAccess> on server. There are lots of posts about this problem and no good solution.
But more complex problem is that YouTube videos can be opened in webinar using api player. And in this situation I have no idea how to resolve security problem. Maybe someone knows a way or workaround to use BitmapData.draw() on YouTube AS3 player?
Or maybe there is another good way to solve my recording issue?
Free Apache Openmeetings conferencing [1] has a java recording application inside which should work in 3.0 release. Just use it.

Im wondering if it is possible to output sound to both headphones and built in speakers at the same time. Iv searched but all i can find is references to possible attemps using android. but my application will be web based, using flash and AS3. Can anyone confirm if this is possible or not?
essentially im trying to make a set of DJ decks, and thus need to be able to listen to 2 sounds separately but at the same time (to beatmatch)
Many Thanks

No, not without a very specific setup. Flash will only output one, globally mixed audio stream from the application. You cannot separate your sounds to be routed to separate outputs.
However, if you're not looking for a general setup but rather a one-off thing where you are able to control the machine it is supposed to be running on - there could be a way. If you are writing an Adobe AIR app, you could write two separate apps:
App A controls the UI and all the sound
App B just receives a sound stream from the first app and plays it
App A then routes the "headphone track" to App B and plays the "main track" as normal.
You could then (maybe) use an application such as Soundflower to route the sound from App A and App B to separate outputs (where one could be the headphones and the other would go to some speakers.)
This all is very dependent on your sound card. You'll most likely need an external sound card to handle the two separate audio streams.
So, I'm working with a video source that I'm feeding into my Adobe AIR application via some native extension work, with the goal of ultimately getting it to a Flash Media Server. The video is H.264 encoded and muxed into a FLV container, which aligns me with supported Flash Media Server codecs and NetStream (appendBytes) requirements. I can get the data into AIR just fine.
The mine I stepped onto today, however, is that documentation for NetStream.appendBytes states I must call NetStream.play(null):
Call this method on a NetStream in "Data Generation Mode". To put a NetStream into Data Generation Mode, call NetStream.play(null) on a NetStream created on a NetConnection connected to null. Calling appendBytes() on a NetStream that isn't in Data Generation Mode is an error and raises an exception.
NetStream.play() called with a null parameter yields local FLV playback. I can't publish the stream to FMS in this mode. But my research into Flash seems to indicate NetStream's byte access is my only real hope here when dealing with non-camera or non-web video data.
Q: Can I latch onto the video playback buffer for publish to a FMS? Can I create a sort of pipeline of NetStreams or NetConnections to achieve this? Or is there an alternate approach here for transmitting H.264/FLV data to FMS? (The source of my video cannot communicate with FMS directly.)
The answer to your question is quite simply no. This is apparently implemented as a security feature, which is probably less of a security based issue and more of a sales issue. Adobe likes to block certain capabilities intentionally in order to create the possibility of, or need of another product aka more revenue.
I tried looking into this for you to see if there was some dirty hack where you could attach a camera or something and override the binary data being sent to the stream like you can with Audio but unfortunately, to my knowledge, no such hack is possible. More nfo here: NetStream.appendBytes
Update
You might be able to do something hackish by using ManyCam which is a virtual webcam driver (from what I understand). This will provide a valid camera you can select from flash and you can also select a video file as the source file for ManyCam. See http://manycam.com/user_guide/#HowtoSelectaVideofileasthePictureSourceforManyCam
Update #2
If you're looking for something open source that will do the same thing as manycam, check out the following:
http://code.google.com/p/webcamstudio/wiki/VideoSourceMovie (GPL Licensed)
I have an interesting project wherein I need to allow users to capture video of themselves with a webcam at a kiosk, after which I email them a link to their video. The trick is the resulting video needs to be a 'slow motion' version of the captured video. So for example, if someone creates a 2 minute movie, the resulting movie will be 4 minutes.
I'd like to build this in Flex / AS3 if possible. I don't have issues capturing the video and storing it / generating and emailing a link, but slowing down the video is the real mind bender. I'm unsure how to approach 'batch post-processing' a set of videos using Adobe tools.
Has anyone had a project similar to this or have suggestions on routes to take in order to do this?
Thanks!

This is absolutely feasible from the client side, contrary to what some may believe. :)

Just adjust the capture rate, which shouldn't be too difficult all the source is there.
Alternatively, you could write an AIR app that launches Adobe Media Encoder after writing a file and launch it with a preset that has FTP info etc. Or you can just use the socket class to connect and upload over FTP.

It is not feasible to do this client-side.
Capture the video and send it to the server.
Use a library like FFMpeg to do your coneversions
I'm writing a game to be run locally, on the user's computer. NOT over the internet.
I want to have a file that will hold the usernames and avatar indices (they're in an array).
I want to know if there's a way to write to files through Flash with AS3. I'm using CS4.
I'd also like to know if you can delete files through Flash, though that's just optional.
Thanks in advance for any help you can give.
If you want to make a game that runs locally on someone's computer, you should make it in Adobe AIR. AIR apps can read and write files, and do all sorts of useful things like show updates in the taskbar, etc. Whereas a simple SWF that you download and run locally can't do anything useful that it couldn't already do in the browser - it can't write or delete local files, for a start. (It can read local files, but only if you disable it from accessing the network.) Moreover, the standalone Flash player is not generally disseminated, so unless the user is a Flash developer they're just going to view your SWF in a browser anyway (unless you plan to publish projectors, which I also wouldn't recommend).
With all that said, however, even if you do your game as local flash content, you can still store information by using SharedObjects. They work the same way offline as online. You can't write the data out as a separate file, but you can store it between sessions easily enough.
if i understand what you are trying to do then why dont you use Adobe AIR? this is flash for the desktop
