Re: [Flashcoders] Auto Webcam Detection
I must apologize to all who have downloaded my class. I have forgotten a
very simple yet important piece of code.
I forgot to check if there were no cameras at all available.
Please replace the begin function with this one:
public function begin ():void {
_numCameras = Camera.names.length;
/* FAIL */if (_numCameras == 0) {
dispatchEvent (new WebcamEvent (WebcamEvent.RESOLVE, null,
noCameras) ); // No cameras available
return;
}
if (Capabilities.os.substr (0, 6) == Mac OS) _isMac = true;
_video = new Video();
getDefaultCamera ();
}
Thanks, and again I'm sorry.

Thanks Eric,
I have not heard about the bluetooth cameras and any related issues. I
wonder if the fps works there as well. It is hard enough for me to get
access to Macs and that's half the reason I made the class.
I initially chose 1.5 seconds for each camera and so far almost all cameras
I have tested have come out of their initial init phase before 1.1 seconds.
I don't have a lot of experience with a lot of cameras so if you say FW
cameras tend to be really slow maybe I should change the default for a bit
longer, but there are properties in the class so you can tell the object how
long it should check for. I put those in for exactly the reason you are
describing. Some cameras take longer, and if the developer using my class
wants to test each camera for a longer period of time he has the ability to.
Thanks for the feedback.

FLARCameraSource checks activity level, just like your WebcamDetection.
however, some users have reported that newer sony vaios have a 'bluetooth
camera' driver that is not attached to a camera (kind of like OSX's 'DV
Video'), but that an activity check on the vaio cam returns activity even
when there is none. FLARCameraSource gets around this by differencing
frames to check for a change in the camera feed. it looks like you're also
checking the reported camera fps; i don't have a vaio so can't check that
technique against the 'bluetooth camera', but i wonder if it works there
too...
also, i notice you're checking across 1.5 seconds for each camera. i have
double that time in FLARCameraSource, tho i'm not happy about it...can take
a while to cycle through cameras. i've found that 2 seconds is borderline,
and 3 is safer, but i'm not sure i trust 1.5 seconds to be enough for all
cameras (some are very slow to init, particulary external FW cameras). any
thoughts on that?
nice work, wish i had found this a month ago, would have saved me some

I've made an update to my class. I added better Mac detection so the
process
goes quicker on Macs. I've also updated the detection math in general.
Please if you downloaded it, re-download and update with the new version.
Feedback is nice, and I hope you like it.

So I've noticed that Facebook will automatically detect which Camera
object
to use on your computer.
It seems on most if not all macs there are at least three (3) Camera
objects
always available.
So, I've made a class that will automatically detect which webcam is
active

Re: [Flashcoders] Auto Webcam Detection
Henrik, The detection is based off of the activity level, so yes the moving image, but its also based off of the fps of the Camera. That way, if my user is a stiff and doesn't move much, but the Camera is good, the fps should be going strong even though the activity is not. Also, I know a lot of users are just too stupid to figure out this whole webcam thing. Heck, I hadn't even used a webcam until I got one on my laptop in April. One thing I have learned is that in your applications, do as much for the user as possible while still making them feel like they have control (but they really don't who are you kidding).
