A brief look into libdc1394-devel archives suggests that the API hasn't been
finalized yet. And it should be possible to install it alongside libdc1394-1.x,
like Nicolas suggests.

Unfortunately, it appears to contain patent-encumbered code:
dc1394/bayer.c:
...
/* Edge Sensing Interpolation II from http://www-ise.stanford.edu/~tingchen/ */
/*   (Laroche,Claude A.  "Apparatus and method for adaptively
     interpolating a full color image utilizing chrominance gradients"
     U.S. Patent 5,373,322) */
void
dc1394_bayer_EdgeSense(const uint8_t *restrict bayer, uint8_t *restrict rgb, int
sx, int sy, int tile)
...

Which is a simple interpolation algorithm. Software patents need to die!
