has anyone gotten V4L2 streaming (mmap) capture to work with bttv 
0.8.31?  i could really use a few pointers on module options or kernel 
configs.  below is the full question:

i'm trying to make the switch to bttv2 to bttv 0.8.31.  i have RH 7.2, 
kernel upgraded to 2.4.16, all of gerd's latest patches applied, and 
bttv 0.8.31 installed successfully.  i can do capture via read() with no 
problem.  streaming capture does not work though, and i need it badly.

here's what happens when i try to run xcaptest from the V4L2 apps 
collection:

G_PARM in capture_init: Invalid argument
S_PARM in capture_init: Invalid argument
QUERYBUF in capture_start: Invalid argument
called v4l2_set_fps with fps=30
time per frame is: 134594864
time per frame is: 333667
time per frame is: 0

when i try to run my own apps, the same kinds of failures occur.  all of 
these worked fine under bttv2.  here's what i have in my modules.conf:

# i2c
alias char-major-89     i2c-dev
options i2c-core        i2c_debug=1
options i2c-algo-bit    bit_test=1

# bttv
alias char-major-81     videodev
alias char-major-81-0   bttv
options bttv            card=10 v4l2=1 mmap=1

am i missing a kernel module or option to enable mmap capture?  can 
someone point me at a doc?  thanks in advance.
