Hauppauge WinTV USB Model 566 PAL-I

Hauppauge WinTV USB Model 566 PAL-I

[Chris Grove]

Hi there, I've got one of these cards but I'm having trouble getting it to
work. The problem is that it loads ok, but when I try to use it, it turns
out that the tuner module has loaded the wrong tuner type. Instead of using
tuner type 1, a PAL-I tuner which mine is, it selects a PAL-BG tuner. Now
I've tried using type=1 in the modprobe line but it turns out that, that is
no longer supported. 

 

System Info.

I'm using GeexBox which is built on linux-2.6.21.3 kernel.

 

The Init.d script is:

#!/bin/sh

#

# setup tv cards

#

# runlevels: geexbox, debug, install

 

echo "### Setting up TV card ###"

modprobe tuner pal=I

modprobe tveeprom 

modprobe usbvision

modprobe saa7115 

 

echo -n "" > /var/tvcard 

exit 0  

 

And the output from dmesg is:

<6>usbvision_probe: Hauppauge WinTv-USB II (PAL) MODEL 566 found

<6>USBVision[0]: registered USBVision Video device /dev/video0 [v4l2]

<6>USBVision[0]: registered USBVision VBI device /dev/vbi0 [v4l2] (Not

Any ideas please, and if someone has already asked this, sorry but I'm new
to the list and haven't worked out how to search the archives yet.

Thanks in advance, Chris.

The option has probably been moved into the decoder module; check to see
if it has facilities for such a parameter with: /sbin/modinfo saa7115

I use marc ( http://marc.info/?l=linux-video ) , but there are a few
other ways too (gmane etc etc).

please try a modprobe tda9887 debug=1 to see some debug messages where it fails.
Proceed like this:
modprobe tda9887 debug=1
modprobe saa7115 
modprobe usbvision
Then, plug-in your device.
Geeksbox is based on mplayer, I tested OK mplayer but with some tuning like this:
mplayer -tv driver=v4l2:width=320:height=240:norm=SECAM:outfmt=yuy2:channels=21-F2 tv://

[Chris Grove]

Hi,
Ok I've tried it and it works, sort of. I've managed to get a picture that
works, the problem now is that the old bug of white lines on the display and
noise on the audio is back. Any ideas if there is a tweak or something I can
use to fix it please??

Do you use external audio or the audio via usb?
Please use the external audio, much better sound quality (44KHz whereas 16KHz via USB).
What are the white lines on the display? Interferences, constant lines, other?

RE: Hauppauge WinTV USB Model 566 PAL-I

[Chris Grove]

Hi,
Yes I am using the external audio, mainly because I haven't got a clue how
to get the audio via USB to work. If you've got any pointers on that,
that'll be really cool I'm not bothered about the 16KHz sound. The white
lines on the picture are constant but move up and down the screen. It very
much reminds me of an old TV fault called sound on vision where the video
and audio carriers aren't separated properly.

RE: Hauppauge WinTV USB Model 566 PAL-I

[Chris Grove]

A further, slightly interesting development is that the s-video input works
fine with no interference at all, also the TV picture in fine in windows.
Just thought that might help with a solution.

Hi,
Yes I am using the external audio, mainly because I haven't got a clue how
to get the audio via USB to work. If you've got any pointers on that,
that'll be really cool I'm not bothered about the 16KHz sound. The white

Do you use external audio or the audio via usb?
Please use the external audio, much better sound quality (44KHz whereas
16KHz via USB).
What are the white lines on the display? Interferences, constant lines,
other?

Right, this helps. We can deduce this does not come from the decompression algorithm since it is the same whether the TV input or the s-video input is selected.
I suspect a tda9887/saa7113 interface problem but just my intuition.
As it works under windows, can you do an usbsnoop (http://www.linuxtv.org/v4lwiki/index.php/Usbsnoop)
Just open the TV application, let it tune the channel and stop the application immediately in order to have a minimal capture file.

For the audio over USB, in the ancient times I developed a audio extension for usbvision. I don't even know what I did from it. I can look for it if you want. I will need to sweep the dust (compilation errors and so on) but should work.

P.S.: this thread is really hard to follow now... please reply under my answer so that we will be able to read that again :)

I found the audio-over-usb code (see attached). The code may need some
cleanups and can cause kernel oops.
The USB snoops need to be analyzed. Can you put it on a site so that I can
download it?
Nevertheless you can read what I wrote when I was programming the
audio-over-usb driver here:
http://thierry.merle.free.fr/articles.php?lng=en&pg=82
The page was translated to English using google translate so there may be
some problems of understanding :) For some more information about the
usbvision chip, I wrote a page here:
http://thierry.merle.free.fr/articles.php?lng=en&pg=68

As a first step, I will look at the register accesses. They begin with a
line like this:
00000000: 00000000: 42 33 00 00
With the datasheet I can understand what the windows driver is setting.

For example here you have a register programming #07 (SER_MODE from the
NT1004 datasheet).
Value is 0x30 (TransferBufferMDL line). Means MODE=3.
This is just for the example, this one is not interesting.
There are other registers more interesting but I should have the complete
log to find out.

You may have sent me the sufficient data to investigate but in doubt give me
the complete logs.
Of course you can look at the problem if you are interested.

Thanks
Thierry

Hi Thierry, Thanks for the links to you code, I'll download it and have a
look. Here's hoping I can work out what's going on in it. I've uploaded the
whole of the log to my skydrive, the link is below. 
http://cid-19380f9184511dde.skydrive.live.com/browse.aspx/Public
To be honest I'm only a learner when it comes to linux and c++ programming,
I'm more of a basic programmer so I need all the help I can get my hands on.
Thanks in advance for all your help. Chris.

Sorry I forgot to attach the patch of audio-over-usb :)
It applies on the v4l-dvb tree and creates an optional module for audio.

usbvision: audio over USB

From: Thierry Merle <thierry.merle@free.fr>

This enables the audio over USB for usbvision that are capable to transmit
the audio data over the USB cable, to get rid of the line-in audio cable.
The quality is poor (16KHz stereo) compared to the line-in audio (44KHz stereo).

OK I have made a quick and dirty perl script that parses the usb snoop file and outputs register programming values.
Usage: usbvision_snoop_extract.pl <UsbSnoop.log

A line is interesting:
Command=USBVISION_LXSIZE_I[00 08 00] value=c0 02 20 01 06 00 01 00
Tells that you must set the X offset to 0x0006 and Y offset 0x0001 (data are swapped).
Please try modprobe usbvision adjust_X_Offset=6 adjust_Y_Offset=1

Hi Thierry
I've tried that line, but it doesn't load usbvision. It doesn't seem to like
the parameters. Is there some way using the CustomCard option??
Thanks Chris

Eeek, I was trying not to upgrade to the next version of Geexbox as it still
has many bugs and I don't really want to add X.org as I'm trying to keep
processor down to a minimum. Recompiling the drivers sounds better as I've
already managed to recompile the kernel a few times. Is there any chance you
could give me instructions on upgrading the driver please?? I'm guessing
it's not as easy as just copying the sources into the Usbvision folder,
although I might be wrong.
