Blue video feeds with timestamp. (fixed)

sde · Post by **sde** » Sat Jan 28, 2006 5:25 am

I feel I am so close, but this is rough. It seems as if my card is just outputting blue. I know 100% for sure the camera works because I hooked it up to the TV.

I'm on FC4, I don' t and I'm using a 4 port card. /dev/video0 (0-3). I only have channel 0 enabled, but I've tested all channels and all video inputs with the same results.

Video Blue with a timestamp in the upper left. This is with JPG or an mpeg stream.

I've checked the logs and nothing looks irregular since before the last successful install. var/log/messages seems fine too.

Monitor settings are:
**********************
/dev/video0
0
1
rgb24
320
240
Normal
**************************

Both monitor and source on the main page are orange, so at least this seems ok.

i turned debug on, but all the logs are jsut like this:

Code: Select all

Did you insmod the card (did you add anything to modprobe.conf)?
What drivers did the kernel load (take snip from dmesg)?
What card do you have?

Corey

i did not use insmod. my linux/hardware knowledge is weak to say the least. i did see posts about modifying modprobe.conf and i did add card=77.

dmesg contains these lines if this is what you're looking for:

Code: Select all

bttv0: using: GrandTec Multi Capture Card (Bt878) [card=77,insmod option]
bttv0: gpio: en=00000000, out=00000000 in=00ffffff [init]
bttv0: using tuner=-1

is there a way to refresh changes you have made in modprobe.conf? i just know to do it by restarting the box.

the card is: grandtec xguard 4 port

Adding a card type in modprobe is a insmod.
77 my not be the correct card. By the way that was exactly what I was looking for

Try removing the insmod and reboot. The newer kernels should autodetect that card.
If that does not work try card=103
I got the card number from list /usr/share/doc/kernel-doc-2.6.12/Documentation/video4linux/CARDLIST.bttv

by default, the OS added this to modprobe.conf:

Code: Select all

alias char-major-81 bttv

demsg related lines:

That should be the only line in your modprobe.conf for your bttv unless you have to force the card type.
options bttv card=103 tuner=4
should only be there if it don't detect the correct card type on it's own. You should remove the options bttv line all together leaving alias char-major-81 then if that don't work, then do

Code: Select all

alias char-major-81
options bttv card=103 tuner=4

yes, it definately doesn't work if i don't define the card option.

it looks like it automatically sets tuner=4 because all i set was options bttv card=103

and this is the dmesg:

Code: Select all

bttv0: Bt878 (rev 17) at 0000:02:0a.0, irq: 11, latency: 32, mmio: 0xf47fe000

bttv0: PLL: 28636363 => 35468950 .. ok

tuner is set.

thanks a lot!

I'm having a very similar problem. My video is very pixelated and blue.

Here is some info...

I'm seeing some odd things in the dmesg output...

RELEVANT LINES ONLY:

Linux video capture interface: v1.00
bttv: driver version 0.9.14 loaded
bttv: using 4 buffers with 2080k (520 pages) each for capture

bttv0: PLL: 28636363 => 35468950 .. ok
bttv0: PLL can sleep, using XTAL (28636363).

It appears that it is trying to use an Osprey 200 card but I added "options bttv card=77" to my /etc/modprobe.conf so I'm not sure what it's really doing now. The card is actually an Osprey 210 and the number according the v4l2 docs is supposed to be 89.

lspci:

Can you help?

Editing /etc/modprobe.conf with "options bttv card=89" does not change video problem. The output to the above commands is correct with the changes made though.

Thanks,

hi, try to use /etc/modprobe.d/bttv instead of modprobe.conf......
so you have to write "option bttv card=77" to the /etc/modprobe.d/bttv
