Please consider adding the letters dv to this name somewhere because there
is another 1394 camera format that is extremely popular called Digital
Camera that sends uncompressed video. If you want to toy around with one,
Orange Micro and ADS Technologies make some for ~110. Perhaps call them
dv1394src and dc1394src.

When my new drivers are done, I'll port your plugins to use them. They
provide better performance through DMA transfers into userspace memory. This
is not possible using the libraw1394 interface you are using. We use this
approach alot with the 1394 uncompressed Digital Cameras, and it helps
performance quite a bit esp. in conjunction with XvShm.
