I'm just lurking but tonight was looking to do the same thing and found this
program for piping live 1394 DV to ffmpeg.

It is thanks to: Ryutaroh Matsumoto <ryutaroh@xxxxxxxxxxxxxx> Maybe it
will be helpful for you.

Gidday there,
I have an application that requires me to take still images (nominally
jpegs), and pop them into some YUV buffer of a video card so that another
piece of software can make funky overlays. Currently the other software
expects a video4linux device making use of the XVideo API.
I'm a newbie to both of these APIs, and I would like to know whether it
would be easier/quicker in one or the other. Unfortunately issues about
portability and doing things the Right-Way(tm) are secondary to my
horrendous time constraints.
Any hints? Clue sticks?
I've just downloaded the 40Megs of mailing list archive, which I'm slowly
going through.
I know absolutely nothing about XVideo, but for v4l, I am guessing that I
would base the driver on some sort of USB device which receives individual
frames. Then I would figure out some sort of FIFO to userspace in order to
allow any sort of networked program to pipe data in.
Any help is appreciated.
Joshua
