 Posted: Thu Jul 13, 2006 8:08 pm Post subject: howto configure and record from tv tuner? |
 |
|
The story:
I recently purchased a cheap TV tuner made by Medion (chip by Phillips) for testing.
I started with Windows to, sort of, make sure the card is working. I got some images so at least I'm positive this piece of hardware is technically ok. The quality of input is another thing, but it's unimportant right now.
I plugged the card into by Gentoo box running not-so-fresh 2.6.12 kernel. I did all the kernel configuration as stated in:
http://gentoo-wiki.com/HARDWARE_saa7134
meaning modules, card/tuner parameters and so on. After hours of trying different options I finally got it working. But, after a reboot, everything was gone and I was forced to start again, unfortunately, without any effects...
That's why I dare ask You to help me to solve this issue...

| Code: | cat /etc/modules.d/saa7134
options saa7134 i2c_scan=0 card=12 tuner=24 |
Testing
I tested the setup using tvtime, my settings are as follows:
- Freq. table: Europe
- TV standard: PAL (default in Europe)
- video source: Television
The card is connected to a tv-antenna with a coaxial cable. When I issue 'scan' in tvtime i only get blue screen with numbers switching from 0 to 140, no image.
Since I DID worked quite well before I think I must have missed something but without your help I'm unable to determine what... Any suggestions greatly appreciated 
Thanks.

In my experience, any card I have wouldn't work with an antenna - it needs a boosted signal.
Have you tried using svideo or composite input? (ie: connect to a DVD player or Camcorder or something)

1) The card does not support composite and/or svideo input, so have to stick with what I have.
2) It's not really an 'antenna'. I just call the source of the signal like that.
Any thoughts? |

Hmmm...
you have the saa7134 in modules/autoload so that you get it from boot, I assume?
dmesg should also leave some message about creating the devices...(and hopefully no errors)
However, I think that the problem is not there. I think "television" is wrong in tvtime, IRC there is also "antenna".
You can try the diffent ones. Also it would not harm to install xawtv and try there as well
whereas I think tvtime has easier tuning of the channels... |

yes, saa7134 is being autoloaded on reboot:
| Code: | cat /etc/modules.autoload.d/kernel-2.6 | grep saa
saa7134 |
dmesg:
| Code: | saa7134[0]: registered device video0 [v4l2]
saa7134[0]: registered device vbi0
saa7134[0]: registered device radio0 |
| Code: | ls -l /dev/v4l/
total 0
crw-rw---- 1 root video 81, 64 Jul 14 18:43 radio0
crw-rw---- 1 root video 81, 224 Jul 14 18:43 vbi0
crw-rw---- 1 root video 81, 0 Jul 14 18:43 video0 |
And it doesn't work... I mean, it sometimes shows an image in tvtime (only in 'singal detection' off mode) but it's very noisy. Looks like wrong tuner setting and/or wrong channel(?), location setting(?).
Any hints? |

I eventually managed to configure the card by myself. The right settings in this case are:
| Code: | cat /etc/modules.d/saa7134
options saa7134 card=12 tuner=12 oss=1 |
However, some other tuners/cards work as well:
| card | tuner |
| 9 | 11 |
| 8 | 51 |
EDIT:
My next question is about recording video/sound from the card. I've read the doc on wiki, but hey, isn't it strange to write 3 lines of text just to record a couple of minutes of a movie?
So, are there any good (read: working) GUI-enabled programes to do the dirty work for me? If not, what should I do to record?
Thanks! |
