This directory contains hacked drivers for cx2388x tv capture cards.

If you build them you get a whole load of new insmod options. 
You can see them using modinfo or by looking at the source (cx88-core.c, cx88-video.c)
Most of the new options are just a way of forcing registers at a certain value.

For example we have the module option cap_raw_all 
cap_raw_all,"A value of 1 enables continuous raw data mode capture."

This just sets bit 6 of Capture Control Register 24 h310180


By making all these registers user_settable it is easier to discuss and test different options without having to change the source and recompile all the time.

For the unpatient:
tar zxvf cx88-0.0.4-mdvh-hack5.tar.gz
cd cx88-0.0.4-mdvh-hack5
make KDIR=/path/to/your/kernel/source
insmod v4l1_compat.ko
insmod ./cx88xx.ko
insmod ./cx8800.ko cap_raw_all=1 frm_size=2048
do some capturing in 8-bit grayscale mode with normal and special capture_sizes (see cx2388x_testsx.txt for explanation) 

I first grabbed the latest video4linux sources and modified them only to find out that they don't compile on my machine.
So I changed back to an older version of the cx2388x video4linux driver.
This one (cx88-0.0.4-mdvh-hack4.tar.gz) does compile on my machine against kernel 2.6.7.
Now there is also hack-7 which is based on the latest video4linux source and only compiles against recent 2.6.x kernels. (2.6.11-rc2 compiles)

                                      The insmod parameters moved a bit around (and must sometimes be duplicated for 
                                      different cx??.ko modules.)
                                      Do a modinfo on all cx??.ko modules to find which parameter is in which module(s).
