Hauppage WinTV-HVR-900H

Hauppage WinTV-HVR-900H

[Ali Abdallah]

Hi,

Very unlucky, i bought a pinnacle hybrid pro and couldn't get it to work 
with linux, then i gave it up, and i found that HVR-900 card works well 
under linux, i got one, but i didn't know that the company is referring 
now for 900 same as 900H.

900H doesn't work under Linux, is there is way to get this card working?

googling i didn't find much information, all i found is work under way 
to get this card supported (2008).

Please help,
.

Mauro was working on this driver some time ago...  There is a current
thread about the tm6010 on the mailing list now, but I have not read
up on it.  Last I heard, progress on the driver has been minimal.

Almost all other Hauppauge products have relatively decent linux
support -- you were unlucky and picked the one usb stick that will
probably not be fully functional for a while.

If you're interested in helping the driver development, then take a
look at the related mailing list posts.  Otherwise, you might be
better off choosing a different product.

On the other hand, I think there's been some recent progress on the
PCTV hybrid pro -- Devin Heitmueller has been doing a lot of work on
those products lately.  For more information, see
http://kernellabs.com

Are you specifically looking for a hybrid analog / digital usb stick?
...or is digital-only good enough for your purposes?

I saw the thread, but no news since quite some time, and trust me, 
searching on the internet it seems a lot of people are getting the 900H 
instead of the 900, it is the hauppage fault here.

That's why i got hauppauge card, but well it was the 900H one.

That's a good new, i can still get that card, probably i can help 
testing the driver.

Yeah, i need to get an analog USB stick to work under Linux, because i 
replaced my desktop with a small imax mini (which i got the windows 
refund for it) but it is a very small PC that doesn't have PCI card.

So basically if i can get the analog part of the PCTV hybrid pro or the 
Win TV hvr900h to work under Linux that will be awesome.

It depends on what your needs are and whether you already own the
device.  If you own an older version of the board already, it may or
may not work depending on which board you ended up with (if you send
the USB ID, I can tell you the status in terms of support).  If you
haven't bought it yet, then the currently shipping version of this
product is not supported (I'm actively working on the support).  Also,
even once I have added the support, it will only be for the digital
part of the card, with no plans at this time to do the analog support.

Cheers,

Devin

I have the card since alsmost 3 years, it never worked, but now i'm in 
urgent need of getting an analog usb stick to work with Linux.

The PCTV hybrid:

Bus 001 Device 004: ID eb1a:2881 eMPIA Technology, Inc.

Thanks for you support, but i need an analog usb stick, well hopefully 
the wintv 900H will get supported soon.

Well, I added support for that device last month, so I would suggest
you install the latest v4l-dvb code from
http://linuxtv.org/hg/v4l-dvb.  Directions can be found here:

http://linuxtv.org/repo

Available from 20th Oct on so in 11 days. There are not many
competitive devices (none) available for
linux which deliver such support. On the other side it's not kernel
based either, it's entirely in userspace.
It's also  entirely supported by all participating companies.
The driver is using the same components as the Windows driver.
There's no way to crash the kernel with that driver, and it works from
2.6.15 kernelseries on
without having to fiddle around.
In any case it's up to the customer if he wants an easy installation
or a complicated one,
similar devices for Mac are available at a higher price.
Even though when drivers are officially in the kernel still not all
distributions are shipping all the kernel drivers
especially the firmware isn't shipped with most distributions either.
We do have customers who are not comfortable with having to compile
kernelmodules and just want
to have it work.
Another positive side effect every system can use the same driver,
updates are easily possible for everyone
(unlike kernel drivers for such devices which have to be recompiled
for every system).
The installation of it usually takes below 10 seconds on any system we
tested (Ubuntu, Redhat, Suse, Sidux,
Gentoo, Acer One Netbook, Arch Linux)

Markus

this is a mailing list for the open source dvb drivers
you are talking about a closed source solution
what does your solution have to do with linuxtv.org?

I see linux-media, you can find the sources of a patched tvtime version on the
website.
It shows an alternative way how to integrate usb chipsolutions in linux.
Aside of that the official DVB(3/5)/V4L(1/2) API has been reviewed
through our work and bugreports have been
submitted to various places (linux media, some linux distributions).
It integrates
flawlessly and helps to improve the overall media support with linux.

The posting was pointing out to Ali's email that he was looking
for a working analog TV solution for France. He has bought this
Pinnacle device 3 years ago,
the vendor does not care about support for it.
We provide solutions which work within a few seconds, nevermind what
distribution.

Although this was my last mail addressing your questions.

Your business is so bad that you can't even pay to an adds on some magazine, for
you to spam the open source mailing lists as a desperate trial to sell a single
unit of your product?

As an information for you it's going very well. Just because you don't
have any influence
anymore in blocking our work as you had done in the past it's better
for you to remain silent in the background.

What a plain nonsense.

Mauro did never block any of your work.

You have been blocked by the "dvb maintainers", and Mauro was excluded
from them and had no authorization to deal with your patches concerning
dvb.

You have been pointed to deal with the few remaining dvb issues with
Oliver, he was backed by Johannes and there was no more noise from Manu
or Mike.

Instead you preferred, and I told you not to do it, to put an ultimatum
on Mauro, to pull in, IIRC, all your 79 patches over the weekend or you
would do something cruel.

Getting it sick,
Hermann

The answer was responsive to the question, a couple of links to software 
which might serve. I would think your going off about it was further 
off-topic, it certainly didn't help the O.P. any. When someone ends a 
question with "please help" I would assume that any answer would be 
better than "we're working on it." Answering an on-topic question with a 
short list of links is hardly "spamming" or even advertising, it's 
called being polite and helpful.

I would rather run commercial software on Linux that open source on 
Windows, thanks, if those are the choices.

After several months of looking I have yet to find any video app that a 
typical office worker can use. Something no more complex than xawtv, 
which has been running fine on FC4 and FC6 for these folks. I would 
certainly consider a commercial solution rather than have them go back 
to the dark side of the force and Windows-7.

i've followed the advice of marcus in the past
and that is why for over a year i had a completely useless piece of hardware
in the end the "real" developers here sorted the problem out

this list is for people who run or want to run the drivers at linuxtv.org
so no, i don't think i was off-topic
he constantly spams the list here with his closed source commercial solution
just about my only job on this list is to counter his bull

with kind regards

I have followed this one too for a longer time too. In general it
seems like that people were
just fighting the existing and working solution from Marcus. I'm
actually glad that someone is standing
up and trying to make everything easier now. It would be more helpful
if you could
add some helpful information how to get the devices work, rather than
complaining about
someone (especially on personal level as it seems) who supposingly
brought up a competitive solution.
The only issue I see is that this announced work is not opensource,
but I'd also rather leave that
one open to the enduser instead of generally fighting against it..
Some people here have an aggressiv
potential it seems.

just my 2 cents,
James

That's your opinion, I do appreciate every mail which is about linux
and TV here commercial and non commercial.
I'm not interested in reading about flamewars or personal attacks.

The problem lies in the easy to use applications and UI being married to 
analog. The Linux digital applications are "build it yourself" like ham 
radio, while the Windows applications are like CB, plug and works. I 
have been trying for months to find any solution for a group of office 
workers who are trying to move off Fedora FC4 and FC6 (tvtime and mostly 
xawtv) and old Windows to new desktop, preferably FC11. I support their 
Linux servers, I am helping find a desktop solution because I believe in 
Linux (ie. I'm donating my time and the price of cards I bought for 
testing).

Their install "support" guy will plug cards in the box, or USB adaptors, 
and install an RPM. He won't install a bunch of RPMs, configure a 
database, and play dba to get mythtv working. The users understand 
selecting transport like digital-cable-us, analog-braodcast-us, S-video, 
and channels. They are not going to look up frequencies, build channel 
tables, of type transponder frequencies in kHz into vlc and similar. So 
if I could find a commercial solution for them, which they could install 
and run with minimal problem, I'd be happy. I like open source, I have 
supported open source back to stuff I wrote on MULTICS, but sometimes 
"working now" solutions are needed, not "help with development." And 
putting a bunch of partial solutions together is fine for Lego or 
Erector sets, not so much for office working wanting to install and use 
an intuitive solution.

Is this list to promote video on Linux, or just some particular 
implementation of it? Is there a better list, where all competing 
hardware and software can be discussed as solutions without people 
getting flamed? I don't want to offend by talking about the wrong 
hardware brand, or software which can be used by a ten year old, but 
those are the kinds of Q&A I thought I'd find here.

Okay, i installed the latest drivers+the firmware of the device using 
extract_xc3028.pl, the device seems to be detected now, i can detect all 
the analog TV of my cable using tvtime, but manually, i mean i had to 
disable signal detection when scanning, otherwise i got no results, 
since the picture quality is terrible.

Of course i'm sure that all the connections (cable to antenna, cable to 
the usb stick, ...) are correct, since it works with my old PC equipped 
with a PCI TV card.

Any advice, what could be the problem? firmware? since you said (you 
added support for this device) should i open a bug report? is this 
device reported as working by other users?

Please help if possible, almost two weeks with no real success.

Could you please provide a screen shot of the tvtime output?

Also, are you trying to capture over-the-air or are you capturing
cable television?

What analog standard are you using?  PAL-BG?

Did you make sure to tell tvtime which analog standard you are using?

Could you try the S-Video or composite input and see if the picture
quality is still bad (as this well help isolate whether it's a problem
with the tuner chip or the decoder.

It is a cable but at the end it is connected to main antenna of the

Yes i'm sure, settings are SECAM, area France.

Same picture quality with S-Video, but with composite there is no picture.

Ok, this helps alot.  This rules out the tuner and suggests that
perhaps the video decoder is not being programmed properly.

Could you please send me the output of "dmesg"?  I'll see about
setting up a tree with some additional debugging for you to try out.

Thanks,

Follow up, i manager to get the hvr 900 instead the 900H, and i got the 
same result with the analog signal, i tried with my friend's windows 
system, same result, no analog channels detected, however i got all the 
channels a hvr pci card, so i expect these USB keys needs really a very 
strong signal, so there is no problem in the driver, sorry for the 
noise, hopefully the 900H will get a driver soon.

The PC cards generally require stronger signals than TV sets. PCI cards are
worse, since there are lots of interference inside the PC box.

It should be noticed that several tuner drivers don't have signal detection (or not
have it implemented). This is the case of xc3028, so you'll need to turn off
signal detection while tuning, and be sure that you're loading the proper frequency
table used on your Country.

This is what i'm doing actually, i have signal detection disabled in 
tvtime+of course the proper frequency for my country, but still i get 
channels with very bad pictures (not watchable) with my USB sticks, but 
i get all the channels with a very good pictures with my PCI card (with 
signal detection enabled), and using the same analog cable+same 
setup+same kernel version.

libv4l does not work!

[Guilherme Longo]

Do we need include any other header file than

libv4l2.h
libv4lconvert.h

to get libv4l working?

I read Hans saying that:

Just replace open("dev/video0", ...) with v4l2_open("dev/video0", ...), 
ioctl with v4l2_ioctl, etc. libv4l2 will then do conversion of any known 
(webcam) pixelformats to bgr24 or yuv420.

But I am getting undefined reference to 'v4l2_open' and 'v4l2_ioctl'.
Can I get some help?

regards!

 You must also "link" your program with necessary libraries, for example

 gcc  code.c -lv4l2

(V4L2_PIX_FMT_SBGGR8) wierd behavior trying to get image from buffer!

[Guilherme Longo]

You guys with more experience could tell me why this strange behavior 
with my app.

First of all, I built my app from a code well known in the Video For 
Linux spec. It is a capture example.

1º - Why is this  /* Buggy driver paranoia. */?
            min = fmt.fmt.pix.width * 2;

        if (fmt.fmt.pix.bytesperline < min)
                fmt.fmt.pix.bytesperline = min;
        min = fmt.fmt.pix.bytesperline * fmt.fmt.pix.height;
        if (fmt.fmt.pix.sizeimage < min)
                fmt.fmt.pix.sizeimage = min;

2º - I am using libv4l, and using the V4L2_PIX_FMT_SBGGR8 pixelformat in order 
to get 640x480 of resolution. Otherwise I get only 160x120!

This is where the problem lies, I can´t get a good image, I am actually 
getting no more than fuzzy image. So I presumed that I am geting smth else 
from the buffer instead of the data I should get. I started checking the parameters and plz, 
have a look at this wierd response: 

fmt.fmt.pix.width:        640   <- Fine
fmt.fmt.pix.height:       480   <- Fine
fmt.fmt.pix.bytesperline: 1920  <- How comes ? It is 3 times more, in the SBGGR8 pixelformat each pixel is 1 byte!
fmt.fmt.pix.sizeimage:    921600 <- The image is (fmt.fmt.pix.bytesperline * fmt.fmt.pix.height)

I believe that this sizeimage should be set to 307200, representing 640 * 480.


Is there someone familiar with this problem and how to solve it??
Great regards.
