Problem with bttv-drivers

gargi · 06-29-2003, 10:00 PM

Hi there,

I have a huge problem. I want to switch to linux instead of windows. my current problem is my tv-card (Hauppauge WinTV PCI-FM). I recently installed the v4l and the bttv-drivers and xawtv. when i run xawtv it tells me "Can't open device /dev/video0" so I looked for the problem and came to the end that the bttv-module isn't loaded.

I have tried to load the bttv-module a thousands of times but everytime I do so, it puts the following message to console:

Code:

/lib/modules/2.4.21-0.13mdk/kernel/drivers/media/video/bttv.o.gz: unresolved symbol i2c_bit_del_bus_Rdd11c972
/lib/modules/2.4.21-0.13mdk/kernel/drivers/media/video/bttv.o.gz: unresolved symbol i2c_master_send_R85828c3a
/lib/modules/2.4.21-0.13mdk/kernel/drivers/media/video/bttv.o.gz: unresolved symbol i2c_bit_add_bus_R8ca8253b
/lib/modules/2.4.21-0.13mdk/kernel/drivers/media/video/bttv.o.gz: unresolved symbol i2c_master_recv_Reffb2cf3

I'm sure that there is one module I've forgotten to load.

After this module there will be the message "Device not found" when insmod bttv..

I hope anyone can help me!

Feel free to ask for some logs!

Try to load the module using modprobe instead of insmod, it'll load dependant modules first so you don't have to deal with this problem.

But, just in case your stubborn the modules your missing are :
i2c-algo-bit
i2c-core

Ok, I loaded these two modules and now the following message appears on modprobe bttv:

Code:

[root@flo gargi]# modprobe bttv

Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
      You may find more information in syslog or the output from dmesg
modprobe: insmod /lib/modules/2.4.21-0.13mdk/kernel/drivers/media/video/bttv.o.gz failed
modprobe: insmod bttv failed

part of /var/log/syslog:

Code:

I think that the module needs the device /dev/bttv is that correct? So now the problem is that /dev/bttv is a folder (don't ask me why!). Maybe it is another device, init_module is talking about?

acid_kewpie · 06-30-2003, 07:15 AM

/dev/bttv isn't a standard device. It might be looking for a systems block device like /dev/v4l or /dev/video0 (i think video0 is controlled via v4l though, not bttv directly). Alternatively it might refer to the card itself. is it clearly listed in "lspci"?

At 00:06.0 and 00:06.1. One device is AFAIK the card and the other one the IR-Receiver...

--- edit ---
Ok, I've looked up the code of bttv.c and come to the result that the Module doesn't recognize my card at all... I'm now looking for the Cardlist...

Another thread by me about the same problem...

hi,
i've got the same problem, well if you are looking for additional information have a look at your kernel-docs file:/usr/src/linux-2.4.21-ac4/Documentation/video4linux/bttv
there is a list of the supported cards and a script for creating the video devices (maybe you must make it executeable) an example modules.conf is also included, maybe it helps.

gargi · 07-03-2003, 12:05 AM

Did you actually get the card running or are you the same state as me?
I think that the bttv driver doesn't recognize my card, because on "lspcidrake -v" there is no vendor or device information about the particular card.

Is there any way to set the vendor and device information manually?

pyro · 07-03-2003, 05:18 AM

Hi,
I managed to get the card working today at 1 o clock in the morning, all i changed was the bios option plug and play os to no and i changed the slot of the tvcard. I think the last thing is more important. It used the irq of the tvcard before, if you want to have al look at the irqs make a cat /proc/pci. My modules conf entrys are

options i2c-core i2c_debug=1
options i2c-algo-bit bit_test=1
alias char-major-89 i2c-dev
alias chat-major-81 videodev
alias chat-major-81-0 bttv
options bttv radio=1 pll=1 card=24
options tuner type=5

S-Vide Composite and sound is working, too. I wonder if the remote control is supported by linux, I don't think so, anyway I'm sitting in front of my computer so I don't need it

The important loaded modules are
tuner 11744 1 (autoclean)
tvaudio 15068 0 (autoclean) (unused)
bttv 78496 0
videodev 7872 3 [bttv]
i2c-algo-bit 9064 1 [bttv]
i2c-core 21192 0 [tuner tvaudio bttv i2c-algo-bit]
soundcore 6276 0 [snd bttv]

If the sound isn't working, check if headphones are working on the tvcard. My soundcard doesn't digitalise the analog input, so I didn't hear it on the digital out.

Good luck

Finally, I found out why the card isn't working!

It seems that I have a CX 23881-27 Chip on my Hauppauge WinTV PCI-FM. That's why I now installed the cx88* modules but now my problem is the following.

When starting xawtv in console (so that the messages appear in console), the following text appears in console:

Code:

This is xawtv-3.85, running on Linux/i686 (2.4.21-0.13mdk)
/dev/v4l/video0 [v4l2]: no overlay support
v4l-conf had some trouble, trying to continue anyway
ioctl: VIDIOC_DQBUF(index=0;type=VIDEO_CAPTURE;bytesused=0;flags=0x0 [];field=ANY;;timecode.type=0;timecode.flags=0;timecode.frames=0;timecode.seconds=0;timecode.minutes=0;timecode.hours=0;timecode.userbits="";sequence=0;memory=unknown): Input/output error
v4l2: read: Input/output error

So, my new problem is that I don't understand the error-message... Maybe there is someone having the same problem (already solved). I'm also unable to set any channels. Is there a manual for xawtv?

Thanks in advance!

Hello,

"I'm also unable to set any channels. Is there a manual for xawtv?"

I had a similar problem...try man xawtvrc

mad_ady · 07-15-2003, 06:31 AM

gargi, Mandrake has a Control Panel that supports configuring the tv card. Try it if you didn't do it already.

To set channels in xawtv you must tune in on them (make sure you have the correct settings), add them to the list and then save the list. It should write a .xawtv file.

As for remote control support, try lirc.

gargi · 07-16-2003, 01:58 AM

Nice idea. I think I've tried it a hundret times. Everytime I press OK, after typing PAL and something else I don't know anymore, a small window pops up and vanishes again.

I actually changed to gentoo Linux.. Hope I will have better luck with this distribution (but I think, if I can get Gentoo running, the tv-card shouldn't be the problem) ;-)

What I've learned so far: If something isn't working, check out everything even if you are sure that the tv-card has particular chipset...
