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

[Sigmund Augdal]

The development version of vlc allready have a access module that uses
microsoft directshow. It is reported to work with webcams and tv-tuner
cards. So the first thing you need to do, is to check if this is enough for
you. Grab a nightly build from www.videolan.org/~videolan/build and write
"dshow://" in the MRL-field

If this doesn't work then try to grab the source from cvs (look at
developers.videolan.org for instructions). The compilation failure you
reported should be fixed there.

I want to make this work in windows. I have all I need to capture frame from the grebber. (all the windows api). I don't know where to start. I try to compile vlc on cygwin ... but I always got error on compiling.
