[vlc] Re: mini howto for low level frame grabber...

[jonathan dumaresq]

no the frame grabber is a 6 video input and it's not directly support in
windows. So I have to write something to make this work.

so is why I want to know if I only write a module will do the job ?

To compile vlc under cygwin is very painful !

3 days now I try to compile vlc...

so
