> Hi Luigi, > > I am going to work on your mods is just that I am on my regular > work schedule. great. I'll leave my latest source at http://www.iet.unipi.it/~luigi/bt848.tgz they include sys/pci/brktree_reg.h sys/pci/brooktree848.c sys/i386/include/ioctl_bt848.h just get it when you are ready to work on them. They have kind of stabilized now, since I have reliable yuv packed and planar mode in single frame capture, plus working support to decode Teletext in software (I had to disable the various lowpass filters on the Y component), so I will not make intrusive changes to the code anymore. > As for your clipping idea , the existing clipping algorithm was > designed for ease of programmability specially with respect to > X.

Now that I am becoming familiar with the Bt848 code I might try to write some code to support the native VIC format (whatever it is). > Last but not least lets shoot for a checking by Monday .
