cx18 analog cable problems

Post #1 of 17 (9197 views)

I have just gotten my HVR 1600 working, well sortof, and I'm running
into some problems. I have used the latest driver from linuxtv.org.
The driver and firmware load just fine and dmesg report nothing which
would indicate an error. When I try and view the tv feed with mplayer
tv:// the following is the output:

$ mplayer tv://

Playing tv://.

When I do cat /dev/video0 > test.mpg then play the file there is no
audio and the video is not clear. I can barely tell what channel it is
but it is in black and white and is very badly distorted.

My linux distro is Gentoo with the latest, 2.6.30-gentoo-r4, kernel.
Can anyone help with this problem? I just want to be able to watch tv
from my linux box, no fancy mythtv or recording.

Hmmm, that should always work. Perhaps trying to use the tv:// option
to mplayer set the cx18 driver to an unusual state. Unload and reload
the module just to be sure you're in a known good state before running
the above test.

Thanks a lot it worked. It's not too crucial but when there is a lot
of motion it seems like every other pixel row is laggin behind the
rest. It kinda looks like something to do with deinterlacing. Is there
some setting in mplayer that can get rid of this.

Also, what is the status of the IR remote that is included with the
HVR-1600? I didn't see too much information while researching the
other topics with the card and linux.

I'm not sure about mplayer. You can try playing around with the MPEG
encoding controls in the driver:

$ v4l2-ctl --help
$ v4l2-ctl -L

It should work with the ir-kbd-i2c module in the latest v4l-dvb sources.

The unfortunate problem is that the latest v4l-dvb branch is broken for
LIRC. I2C subsystem changes in the latest kernels broke the interface
LIRC used to hook up to I2C connected IR chips within V4L. I updated
the cx18 driver to at least work with ir-kbd-i2c. LIRC is undergoing
updates by Jarred Wilson, so that one day lirc_i2c and lirc_zilog (aka
lirc_pvr150) will work again. See discussions within the past year on
the linux-media and linux-kernel mailing lists.

I need to do an analogous change for ivtv, but haven't gotten to it yet.

Andy

Alright thanks. I'll mess with it when I have more time, classes have
just started for me. I appreciate all the help getting it working, it
was bugging me that it was working in Windows but not Linux. Keep up
the excellent work bring free software to the Open Source
community.

Hmm, I must have gotten lucky when I downloaded a version 8 days ago. LIRC is working for me with the HVR-1600. FWIW, the ir-kbd-i2c module is not loaded. Here are the i2c modules I do have loaded:

$ lsmod|grep i2c
lirc_i2c 18948 1
lirc_dev 22088 1 lirc_i2c
i2c_algo_bit 15364 4 cx88xx,ivtv,bttv,cx18

Here's a link to the changeset I downloaded, in case it helps someone:
http://linuxtv.org/hg/v4l-dvb/rev/3f7e382dfae5

IIRC, LIRC didn't work after compiling, installing, unloading and modprobing cx18. But it did after a reboot.

Hmmm. Well then good. It's more than what I would have expected. The
breakage I would have expected is probably kernel dependent then.

I know I2C subsystem maintainer worked with me to keep ir-kbd-i2c
working when he did his changes to the kernel. (LIRC is out of kernel
right now, so changes to the kernel don't wait for LIRC.) I'm not going
to look at it too hard at the problem, and am happy that it continues to
work for you.

What kernel version are you using?

Andy

I'm using 2.6.28-14-generic, Mythbuntu 9.04 distro. I did a synaptic update at that time, which included security updates to the kernel, and thought I'd use the latest v4l-dvb. I had been using your cx18-av-core-9beb99150ab1 until that time.

Can you help me understand why lirc_pvr150/lirc_zilog is not in the
mainline lirc? I've gotten information on these from you before, and
I've downloaded them and fooled around a little, but really digging in
is still down a ways on my things-to-do list. Gentoo has has lirc at
0.8.4 for a long time, and recently moved to 0.8.5. The lirc_pvr150
patch I saw was against some 0.8.5 version, and I've never actually seen
lirc_zilog, only heard about it. At least one reference was on lkml, so
it sounds as if there has been at least one attempt to get lirc into the
mainline kernel.

Thanks,
Dale

Nope. :)

I suspect it has something to do with the "firmware" image that is
extracted from the Windows driver.

lirc_zilog is the new name for lirc_pvr150 that Janne and Jarod gave it
when trying to get lirc into the kernel the first time. The Hauppague
HD-PVR, for which Janne maintains the hdpvr driver, also has a Zilog Z8
microcontroller for IR.

Jarod's still working it.

http://git.wilsonet.com/linux-2.6-lirc.git/?a=shortlog

It looks like he just merged the recent kernel changes into his working
lirc repository, so you'll have to scan through the summary for lirc
related stuff. (If you care...)

When I try and load ir-kbd-i2c it reports:

ir-kbd-i2c: ir-kbd-i2c: Unsupported device at address 0x71

in the output to dmesg. The command used to load the module was:

# modprobe ir-kbd-i2c hauppauge=1 debug=1

If this is a bug where should I file it and what additional information
would be helpful?

Well good news. I decided to bite the bullet and just do a reinstall of Fedora and now things work. Thanks for the help.

Cool.

I've had a DTV STB connected to my HVR-1600's Analog TV RF input and
haven't been able to reproduce the problem with Fedora 10.

I was almost to the point of setting up Fedora 11. (I think I'm going
to wait 'til 12).

Andy

Argh, this bug belong to me. I either didn't do the changes to
ir-kbd-i2c.c:ir_probe() properly or cx18/cx18-i2c.c:cx18_i2c_new_ir() .

What kernel version are you using?

Are you using the ir-kbd-i2c and cx18 drivers compiled from the latest
v4l-dvb repository?

I never tested these changes as I don't have a 2.6.30 kernel availbe in
my home setup. I guess I'll need to download one and do some real
testing.

Andy
