Hi, there is comments from our expert

It seems that the code is run on Linux.

Make sure that the latest version from CVS is used (that provides much video capturing support than beta 4).

Install libdc1394 and libraw1394, then configure and build OpenCV.

If it still does not work, probably, some extra initialization and color conversion code should be added to cvcap_dc1394.cpp.

Vladimir
