Mauro,

Please pull from

http://linuxtv.org/hg/~awalls/cx18

for the following:

cx18: Fix coding style of a switch statement per checkpatch.pl
cx18: Normalize APU after second APU firmware load
cx18: Smarter verification of CX18_AUDIO_ENABLE register writes
cx18: Defer A/V core initialization until a valid cx18_av_cmd arrives

Note that in my new setup on Fedora 10, kernel 2.6.27.9-159.fc10.x86_64,
the automatic checkpatch doesn't seem to be working. (I think it's
missing the --no-tree argument.) Here's what I get on commits:

# WARNING: /lib/modules/`uname -r`/build/scripts/checkpatch.pl version
0.21 returned some errors.
# Please fix.
#
# Must be run from the top-level dir. of a kernel tree
#

Regards,
Andy

I do this:

$ v4l2-ctl -v width=480,height=480,pixelformat=MPEG

And look what I find in the log:

Feb 28 11:41:37 palomino kernel: cx18-0 843: 480x480 is not a valid size!

Oopsie. The cx18 broadcast A/V decoder driver code is unhappy, and that
code was significantly perturbed by the recent changes.

Thanks for the testing and reporting. I can reproduce your symptoms.
I'll work on a fix this weekend.

Regards,
Andy

Fixed (I missed a non-obvious magic number with sliced VBI changes). If
you want to test, please try the latest at:

http://linuxtv.org/hg/~awalls/cx18

It works for me.

Andy
