Configuring TV tuner card PixelView PlayTV Pro in Linux

Configuring TV tuner card PixelView PlayTV Pro in Linux

Post by José Romildo Malaqui » Sun, 10 Mar 2002 13:06:40



Hello.

Recently I have acquired a TV tuner card. It is a Prolink
PlayTV Pro (PV-BT878P+ W/FM Rev. 8E). But I am having
difficults in configuring it in my Red Hat Linux 7.2
(with upgrades) system, even after reading the bttv driver
documentation on the kernel, the xawtv manual and the
BTTV Mini-HOWTO.

I have already tried the following:

   # insmod bttv card=37 radio=1

with the following log out in /var/log/messages:

   i2c-core.o: client [Philips PAL] unregistered.
   i2c-core.o: adapter unregistered: bt848 #0
   i2c-core.o: driver unregistered: i2c TV tuner driver
   bttv: driver version 0.7.83 loaded
   bttv: using 2 buffers with 2080k (4160k total) for capture
   bttv: Host bridge is VIA Technologies, Inc. VT8367 [KT266]
   bttv: Bt8xx card found (0).
   bttv0: Bt878 (rev 17) at 00:0a.0, irq: 10, latency: 32, memory: 0xee000000
   bttv0: using: BT878(PixelView PlayTV pro) [card=37,insmod option]
   i2c-core.o: adapter bt848 #0 registered as adapter 0.


   i2c-core.o: driver i2c TV tuner driver registered.

   bttv0: i2c attach [client=(unset),ok]
   2c-core.o: client [(unset)] registered to adapter [bt848 #0](pos. 0)

And v4l-conf gives me:

   # v4l-conf
   v4l-conf: using X11 display :0.0
   dga: version 2.0
   mode: 1920x1440, depth=24, bpp=32, bpl=7680, base=0xe0000000
   /dev/video0 [v4l2]: ioctl VIDIOC_QUERYCAP: Invalid argument
   done

Also I do not know which frequency table I should use
with scantv (from the xawtv package). If I run

   # scantv -n pal-m

   please select a frequency table
      0: us-bcast
      1: us-cable
      2: us-cable-hrc
      3: japan-bcast
      4: japan-cable
      5: europe-west
      6: europe-east
      7: italy
      8: newzealand
      9: australia
     10: ireland
     11: france
     12: china-bcast
     13: southafrica
   nr ?

I am presented a set of frequence tables to choose one from,
but none of them seems to be adequate for use in Brazil.

I would apreciate any tips from people using a TV tuner
card with Linux.

Also I would like to know which options I have for watching
TV on Linux, besides the xawtv program.

Regards.

Romildo

 
 
 

1. Btaudio and PixelView PlayTV Pro

Hi,

I am new to Linux and is trying to get the analog audio ADC on the
Prolink Pixelview PlayTV Pro card (PV-BT878P+ version .9D) to work.
There are descriptions mentioned at
http://www.domenech.org/bt878a-adc/index-e.htm but what I got are not
the sampled data. It looks more like a saturated input when the
waveform is viewed using Audacity.

I am trying all these using the live Linux CD listed below. Btaudio
comes together with these distribution.

1) Knoppix with kernel version 2.4.26
2) Cool Linux with kernel version 2.4.22 and 2.4.20

All got the same result, saturated waveform. I have tried all
combination of mixer inputs but to no avail. To be sure thats the
correct mixer, I remove the
PC sound card module using "rmmod via82cxxx_audio". Btaudio is loaded
using
"insmod btaudio"

The wav file is created using
sox -w -r 32000 -t ossdsp /dev/dsp1 -t .wav sound.wav

/dev/dsp1 is the correct device as seen from /var/log/syslog

Anyone manage to get proper recording on the PlayTV Pro card ?. Or
anyone have any hints for me on how to get the recording to work ?

Regards,
HowChee
