As far as I know, you can use the v4l API (ioctls) and and develop a tv app with any card listed (supported) in bttv drivers. The driver takes care of low level issues for you. What you have to do in user level is call the correct sequence of the v4l ioctls and some other details related to your graphic application. > > I'm thinking of the following software structure: > > Capturing App > | > | > v > My SDK > | > | > v > Video for Linux See videodev.h in the kernel includes. > | > | > v > Device driver See the bttv driver in the kernel source tree. > > > Eric Chao > Software Engineer > Merlin Software Technologies, Inc > Hope this helps, Daniel > > > > > _______________________________________________ > Video4linux-list mailing list > Video4linux-list@xxxxxxxxxx > https://listman.redhat.com/mailman/listinfo/video4linux-list > >
