hoo mike..
first of all, i just have to tell that the care you are giving to your
"customers" is SO complete that it is simply overwhelming my expectation.
i'm a long time user of free software and completely sold to this
win-win community attitude (think positive) and i daily struggle to make
my management aware of the big advantages of the free (as freedom)
software strategy and the subtle social implications of this way of
think and act in a truly cooperative mood and i believed to be quite
accustomed to the community standard "SLA" but your words are so clear
and so positive expecially for a simple clueless unknown user like me
that i am without better words to tell you my gratefulness.
now stop the chat and get down to business..
i have read more carefully your web pages and they are indeed packed of
informations to a such level and consistence unbelievable.
expecially when one thinks the really long chain of ever changing
packages involved!!
kernel - v4l-dvb - ivtv -pvrusb2
when i wrote my first email, i didn't understand completely that i
already had on my disk two complete pvrusb2 stacks:
- the 2.6.18 kernel
- the v4l-dvb 24.2.07 tree
but i have been acting as everyone in the free software frenzyness.. get
the latest. what a newbie error! :-)
now i'm getting back to try to patch and user the pvrusb2 of the v4l-dvb
tree (because i'm already using other linux dvb drivers like cinergy
pinnacle and animation..)
and i have to tell, things are going a lot better..
i had to change just one line to fake a Hauppauge 24xxxx
pvrusb2-hdw.c: [PVR2_HDW_TYPE_24XXX] = { USB_DEVICE(0x0ccd, 0x0039) },
and put these three files inside the firmware directory:
...$ls -l /usr/lib/hotplug/firmware/v4l*
-rw-r--r-- 1 root root 376836 2007-03-16 12:37
/usr/lib/hotplug/firmware/v4l-cx2341x-enc.fw
-rw-r--r-- 1 root root 16382 2007-03-16 12:37
/usr/lib/hotplug/firmware/v4l-cx25840.fw
-rw-r--r-- 1 root root 8192 2007-03-16 12:37
/usr/lib/hotplug/firmware/v4l-pvrusb2-24xxx-01.fw
bingo. when i connect the terratec grabster av400 i get a warm green
light on the device..
these are the modules involved:

anyway, the device get the same VID/PID on lsusb
== lsusb ===========
Bus 005 Device 004: ID 0ccd:0039 TerraTec Electronic GmbH
====================
i see too these errors WRT:
- cpu assert (!)
- uploading firmware1 (what's this? mpeg encoder or video decoder?)
- jammed device
anyway, i get the /dev/video0 entry in the /dev directory..
nb-venturi:/home/andrea/src/v4l/v4l-dvb# ls -l /dev/video0
crw-rw---- 1 root video 81, 0 2007-03-16 22:27 /dev/video0
as explained in the web pages, i have been able to do:
cat /dev/video0 > test.mpg
for a few seconds and i get a real mpeg ps file. at least, mplayer tell
me so:
== mplayer log ==========================
....

==========================================================================
the standard input is television (still related to the hauppauge: in
this device there's no tuner; maybe we'll purge it later..)
andrea at nb-venturi:~$ cat /sys/class/pvrusb2/unit-a/ctl_input/cur_val
television
but if put a source in the composite input, and if i set the ctl_input
to s-video (!) i can get in the mpeg ps file a good black and white
recording.
andrea at nb-venturi:~$ echo s-video >
/sys/class/pvrusb2/unit-a/ctl_input/cur_val
andrea at nb-venturi:~$ cat /sys/class/pvrusb2/unit-a/ctl_input/cur_val
s-video
SO NOW THIS IS A SUCCESS STORY! :-)
now, i can already get a black and white video from the composite input
of the grabster av400! hurrah..
now i get these more info in dmesg:

=============================
it's such an easy task to program this device thru the /sys/ fs and with
such rewarding, that i'd like to test the PAL setting
and i'm wrong again.. :-)
i tried some of these settings..
echo "PAL-B/G" > ctl_video_standard_mask_available/cur_val
echo "PAL-B/G"> ctl_video_standard/cur_val
but with always a black and white image..
anyway, it's enough for today (23.44 local time..)
i just can see these more info on dmesg

BTW, i don't see "transport stream" in the pack of streaming type.. so
it's missing on purpose because it's not a hardware thing but just a
software made container, or there's something more to do to get it?

now what to do?
i have a bunch of questions, maybe i could just wade in the code
tomorrow, or i can do some educated question today.
- in the beginning, wrong firmware ? which one mpeg encoder or video
decoder?
- i should raise the level of the debug to get a better idea of stuff going?
- i should begin to "make up" a clean entry for this terratec?
all in all, it seems it's just a matter of tweaking the right bits
(GPIO?) in the right registers.. but i'll need to proceed with trial and
error or there a cleaner path?
anyway, thank you again for this driver. it's really a wonderful
project, and not only for the quality of the source code, but it's
really all about the carefulness of the maintainer
