TV Video capture card Kworold PVR-TV 7131SE

Post by JulijanAndjelic »

Hi people,

I have bought this used card and trying to get it working on my linux mint.

I did a lot of research and I'd say, if it's possible to make it work, I'm on a good track. I need some help though.

I'll share what I've found out so far so we can come to a conclusion together, and hopefully make it work for me, and others using the same/similar card.

First thing first, lspci:

Code: Select all

04:01.0 Multimedia controller: Philips Semiconductors SAA7131/SAA7133/SAA7135 Video Broadcast Decoder (rev d1)
Good start, we know the chip which the card uses, which lead me here.

Now we know which driver (kernel module) has to be loaded, and so I did:

Code: Select all

modprobe saa7134
And the command ran smoothly.

All that said, my card is still not working.

When I was about to give up, I remembered that dmesg often knows what the problem is, and it was the case this time.

Code: Select all

Cute, a little rant and clearly stated what the problem is...but it wasn't as cute finding out that my card isn't (or is it?) listed here.

Ok, so we know that the driver is loaded and working, and that it supports my card, I just need to tell it which card number it is.

I've tried unsuccessfully with 59, but I'm not even sure I've done it the right way. This is where I need your help.

I've created a new file /etc/modprobe.d/options.conf with the following content:

Code: Select all

options saa1734 card=59
It didn't seem to change anything, same message in dmesg...

Thank you for reading my long post through, hope we will manage to solve this and eventually I'll be able to enjoy some TV after a few years of not watching it :D

Re: TV Video capture card Kworold PVR-TV 7131SE

Post by JulijanAndjelic »

More investigation tells me it must be 112 or 125, tried with both + reboot but same result.

Must be that /etc/modprobe.d/options.conf is either ignored or my syntax is incorrect. Any ideas?

I just did more investigation to find that more users had problems with ignored /etc/modprobe.d/options.conf
I've tried the suggestions from the user from this topic, but it didn't help in my case. I'm not even able to execute the rmmod -f saa7134 as it's used by another module (saa7134_alsa) which I tried killing but it kind of froze my system so rmmod probably isn't the best solution.

More research (post from RaSca here) allowed me to see the following:

Code: Select all

If these are true, that proves that the above mentioned file is ignored. I didn't really go into what the function actually does but I believe it shows the right values.

So, the new question would be, how to pass kernel module parameters on system boot?

Thanks in advance for reading through all this, it's like, even if you don't write anything you've done much. I'll greatly appreciate any help though.

EDIT 2:
I managed to make the driver recognize the card. Card number was 2. I ended up writing a little script which would reload the deivers with different card no and then test if tvtime sees the card, it will stop once the card is recognized telling you which card no to use:

Code: Select all

for i in {1..187}
do

echo "------ PROBING $i ------"
rmmod saa7134_alsa
rmmod saa7134
modprobe saa7134 card=$i

cat /dev/null > /tmp/saa7134_detector
tvtime-scanner &> /tmp/saa7134_detector

	if (cat /tmp/saa7134_detector | grep -q "No tuner found")
		then echo "Not found at card $i"
		else echo "**** FOUND AT $i ****"
	fi
sleep 6s
done
I had to run it as root from safe mode.

Once you have the card number make a file:
/etc/modprobe.d/saa7134.conf with the following content:

Code: Select all

alias char-major-81 videodev
alias char-major-81-0 saa7134
options saa7134 card=<card no> tuner=<tuner>
I still don't have a picture though the card is recognized and now I have the scan channels option in tvtime. I believe the problem is that I must specify the correct tuner but I still haven't managed to get it to work.

Does someone have an idea which tuner number should I use?
