Re: LoopBack Feature?

[Cristian Thiago Moecke <birkoff inf ufsc br>]

Well, I'll try to explain better (sorry about my english, not a
nativeenglish speaker as you all should already have noticed).

My idea is to work on a vloopback like system for v4l2. For ME it would
be usefull for fliping the webcam, but I think it would be nice to use
the other effects on webcam image on ANY software. 

But why I am here, on cheese list about it?

For v4l devices, effectv works for that, USING vloopback. All effects
you aply can be used on skype, on amsn, on ekiga, because effectv output
feeds a vloopback device that can be used by this software. Is realy
nice. But obsolete. People are not working anymore on effectv and
vloopback. 

Then I found Cheese. It is active, growing, working with v4l2. Excelent.
So I was thinking: well, why not try to make a vloopback for v4l2, AND
make cheese work with it like effectv works with vloopback. I WILL try
to work on it. But then I was thinking: well, maybe anyone is already
working on something like this. Or maybe anyone someone get interested
on working on it too, to show all skype friends Cheese effects :o). And
thats why I sent the email to the list.

Well, I hope now I was clear on what I want/mean :)
