Has anyone build a AS3 Camera-Select-algorithm, ready to use?
With MacBooks you have the problem that the build-in webcam is not rightly choosen from the webplayer.
You have to select the USP-Cam by youself from the list
DV Video
IIDC FireWire Video
USB Video Class Video
by
camera = Camera.getCamera("2");
THNX!
I found kind of a workaround here
You cant actually set the camera programatically. The best you can do is prompt the user to set it next to a video panel to show them if the camera they've chosen actually works. example here: http://www.neave.com/webcam/
to prompt them to change cameras you use:
Security.showSettings(SecurityPanel.CAMERA)
there is no event to wait for, though you can poll your video panel's bitmap data for changes and prompt the user behind the security panel when you think they've chosen the right camera.
Having done battle with this problem, I would suggest that everyone use this library.

Flash + webcam should = easy + awesome.
Unfortunately, it is pain + suffering.

I understand how to record microphone input in AS3 from this doc.
Is it possible to record sound exactly as they are being output/played?
The reason is I applied some sound transform (via the global SoundMixer) to sounds that are currently playing; and I also want to record this sound data while it is being played.
I just saw this question, to clarify, I am not trying to record just all sounds on the user's computer (which is not possible). My flash app has a Youtube player in it (via their AS3 API), and it's playing some sounds. I applied transforms using SoundMixer.soundTransform, and I want to record what's being played when the user is playing it.
Thanks in advance.
Just a passing suggestion.. on my desktop it seems ABLE to record sound into Flash from a different tab playing Youtube (HTML5).. I don't know how it's doing that!!
I allow microphone here.. (none actually plugged in, and speaker out has in-ear headphones)

PS: Anyone trying this must reduce Windows volume since anything above 10-20% is distorted audio into the Flash app.
And this HTML5 youtube trailer was recorded fine into the Wav file produced by Flash app above

So after a quick search it seems my Realtek Audio is classed as a Full-Duplex soundcard and also within its own control panel I have an option called "Multi-streaming" which is enabled/ticked. I think Full-Duplex is enough to do this though. Try options within your soundcard's own settings software. Don't know about your end-users. Some hardware will do it, some wont, there is no all-round solution outside of AIR (which makes desktop apps out of your AS3 code).
I have made a flash as3 project in adobe flash pro with the dimensions 20px x 150px.
i would like to ceep it this size, but the problem is that my application needs to ask for the MICROPHONE premissions
( like in the image )
but this only happens if the flash object is big enough.
are there any workarounds with maybe the "overflow = visible" method or something ?
thx for any help
Here are a couple of options:
Temporarily increase the dimensions of the SWF in HTML. I've never done this, but I imagine it would work and is the most simplest solution.
Use wmode="transparent" or wmode="opaque" in your embed code. In both of these modes you can layer HTML on top of or underneath the Flash object. The SWF should be sized so that it is big enough to display the dialog. When the dialog is not visible, you can hide portions of the Flash app by covering them with HTML.
I've used the 2nd option successfully, not for this purpose, but for showing some HTML elements (arrow images and text) to guide the user through these "allow" camera/microphone dialogs.
For both of these options to work, you need to be able to detect when the user has closed the dialog. Though there is no official Flash API for doing this, however, there are some good work arounds for doing that.
I want to write a Windows Store App that can capture video (without any sound) and take pictures. Imagine a digital camera: you can preview the picture on the screen of your device before pushing the button which takes the pic.
The problem I'm facing now is the fact that the Windows.Media.Capture namespace has only classes for objects that capture video with sound (CameraCaptureUI, MediaCapture). I'm not troubled by the objects' capabilities, but by the fact that I will have to include in the manifest of the app the Microphone capability and it does not make sense for the app to use it. I need a class that uses only the Webcam capability.
Any ideas?
I found the answer and I thought I should share it. I'm sorry for answering my own question, but here goes:
One can specify in the settings of the MediaCapture object, when initializing it, that it will use only the Video part:
var mediaCaptureMgr = new MediaCapture();
var captureSettings = new MediaCaptureInitializationSettings();
captureSettings.StreamingCaptureMode = StreamingCaptureMode.Video;
await mediaCaptureMgr.InitializeAsync(captureSettings);
RTFM!
Is there some straightforward technique to play only a certain part of a HTML5 video? For example in a 30 second clip I would like to play only the part 5-20 sec. Additionally the rest of the video should not be accessible from the UI at all (meaning the video timeline should only show the 5-20 sec part).
I've been going through some HTML5 video players but none of them seem to be supporting this kind of functionality. If anyone knows a (good) way to implement this feature please give me a hint.
Thanks in advance!
Even though this question has already been marked as answered, here's something that may interest you and anyone else who stumbles across here: Specifying playback range.
It's part of the Media Fragment API and currently works in the latest versions of Firefox, Chrome and Safari 6+.
You can implement it there is a Player.Play() event in a players, whenever Play() called start a timer and call the Player.stop() on the specific time you want.
I got the same problem and I didn't found something that can solves this problem, what you can do is to implement your own controls and display the video with a canvas...
and if you are trying to implement this in IOS you will not be able to do it.
My thought would be to use custom controls, as I don't believe that functionality is available natively. All the functionality of html5 controls (play, pause, start at timestamp, etc.) can be called via javascript. In this case you are going to want to edit the currentTime variable.
So you may want to consider setting up your own slider, where the start of the slider represents your starting point, and the end your ending point. Set the video to not play on page load. Then on page load have a javascript function change the currentTime to your starting point. For stopping you could occasionally query the currentTime. I wouldn't use a timer as delays like slow loading could throw it off.
I am trying to implement a similar video in "Preview Mode". I am utilizing the methods stated above by adding an event listener and then pausing the video at a currentTime()=='x' postition. To prevent user from simply hitting play again, the currentTime listener wont allow playback past the 'x' time in the timeline so each time the user hits play, it is automatically instantly paused again. Furthermore, at time 'x' the video container will become hidden through CSS thus preventing interaction from the user with the video.
The flash player has a little window that can be opened (similar to flash->settings) telling the user to update the player if the movie loaded is for a more recent version. How can you instruct the player to do this? ITV have managed it with their catchup-tv player.
Context: I am allowing users to copy flash into their PowerPoint presentations and would like to tell them to update their flash player if necessary. I am not embedding a web page in the power point so no JS can be run for checking etc (because I know this is not necessary).
Thanks in advance
For getting the current version of flash:
var version:String = Capabilities.version;
I don't know what ITV has done, but I don't know of any way of forcing the player to show that box, although it may do it automatically.
EDIT:
I just found a complete blog post that answers this.
There is no way to force the window to open itself. It's a user defined setting:
Have a look at the Security class. I have used it in some Flash to prompt users to increase storage limits. The panels that you can show are found in SecurityPanel. However, this may not be the way to prompt for outdated Flash version. (If you are looking to customize these panels, that is off limits.)
You can actually test the browser/Flash version in Javascript, so there really is no point in loading Flash to tell the user to upgrade Flash.
