I'm trying to upgrade some old V4L2 device drivers to 2.4 (looking at http://bttv-v4l2.sourceforge.net/download/videodevX-061000.tgz ). I'm noticing that the v4l2-cc.[ch] files are not used anymore. What happened? Is there any documentation that describes the changes that need to be made to rid yourself of dependence on these files? Thanks, Chris
