Hauppauge ImpactVCB-e 01385

Hi Guys,

Sorry to go on about the Hauppauge ImpactVCB-e 01385, but it's a couple of years and version 12.04, since I last asked.

This page:

http://linuxtv.org/wiki/index.php/Hauppauge

Now shows:

Table of analog-only devices sold by Hauppauge Model Standard Interface Supported Comments ImpactVCB-e Video PCIe ✔ Yes No tuners, only video-in. S-Video Capture works with kernel 3.5.0 (Ubuntu 12.10).

As my distribution is 13.10 with kernel 3.11, I believe it should work.

uname -a gives:

3.11.0-19-generic #33-Ubuntu SMP Tue Mar 11 18:48:34 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

When I plug in my 01385 I get the same old stuff in dmseg, ie:

cx23885 driver version 0.0.3 loaded

[ 8.921390] cx23885[0]: Your board isn't known (yet) to the driver.
[ 8.921390] cx23885[0]: Try to pick one of the existing card configs via

[ 8.921393] cx23885[0]: Here is a list of valid choices for the card=<n> insmod option:

Etc.

Does anyone have any idea of the issue here?

Best regards

Steve

Sure. The issue is nobody cares enough to update the driver to support your card and make it work out of the box.

So I'm back to the Hauppauge ImpactVCB-e 01385.

Apparently it's fully supported by the current Linux kernel:

Model Standard Interface Supported Comments
ImpactVCB-e Video PCIe ✔ Yes No tuners, only video-in. S-Video Capture works with kernel 3.5.0 (Ubuntu 12.10).

http://linuxtv.org/wiki/index.php/Hauppauge.

So is this a typo or have I just encountered an install problem?

Would the daily build resolve this? I haven't installed it on this test system, but I'm never clear when I should install it or whether I should just download a single driver from somewhere.

Regards

Steve

I have serious doubts whether this is actually supported. I see no mention of that board in the cx23885 driver. I wonder if there is a mixup between the ImpactVCB (which IS supported) and the ImpactVCB-e.

You can try some of the existing cards: one of 1, 2, 3, 6, 20, 24, 32 might just work. Look in drivers/media/pci/cx23885/cx23885-cards.c.

Each card definition there defines the inputs that are supported by the card. There is no perfect match, so you will have to change inputs to see which input produces an image. You can also add a card definition yourself and just fiddle around with the vmux/amux/gpio values to see which work. It is probably something close to what is used by other Hauppauge cards.

There is no point in using the daily build. The cx23885 driver hasn't been updated in a long time.

Regards,

Hans

Hi Hans,

Thanks for this, I'll do as you suggested.

Do you think there is another internal card out there that would do the job of capturing raw SD video?

What would you recommend.

I'm currently using the Dazzle DVC100, stripping the case off and installing it internally with cable ties. It's just a bit basic. I'd like something a bit more professional like a half-height PCIe board. Which is why I selected the ImpactVCB-e, but really I have no attachment to it.

Regards

Steve.

Actually, I would recommend that you try playing with the 'card=' option to see if you can get something that works. I suspect that adding support for this card isn't hard.

Alternatively, you can wait. I've ordered this card myself (it's about time I start cleaning up the cx23885 driver, so some extra hardware to test with won't hurt) so once I have it I'll work on adding support for it to the cx23885 driver. The problem is that it has to be ordered, so it may take some time before it arrives.

There aren't all that many alternatives available for PCIe (PCI is easier). You can look at the list of supported cards in cx23885-cards.c and see if you can get any of those other cards.

Regards,

Hans

Hi Hans,

Well I did try the card= option before and it worked in a way. The raster was compressed though and the image was not really acceptable.

I'm happy to wait.

Is there something I can do in the mean time? If I can download some code and start playing, I would do so if I knew where to look.

Tell me where to start and I will do.

Regards

Steve

PS In fact I think I have 2 x ImpactVCB-e's, so if your card is very delayed, I could send you one. If you're in the Netherlands it won't take long to get to you.

Hi Hans,

Well, I've been installing the patch today. I finished the compilation script and the card is not detected. Here's what I did:

It's been a bit hard-going because my ISP has been on a go-slow and everything has taken much longer than it should.

1    I did a fresh build of linux tv.  Deleted ~/linuxtv/media_build and then typed:
2    user$ git clone git://linuxtv.org/media_build.git
3    user$ cd media_build
4    user$./build --main-git

This seemed to be fine.

5    tried to apply the patch (patch -p1 cx23885) but had issues (only the main ...card.c was updated and ....h and ...video.c were not updated).  As it was only one line each, I applied the updates manually.
6    user$ cd media
7    user$ sudo -s
8    root$ make -C ../v4l  (it scrolled up quickly, but completed with no apparent errors
9    root$ make -C ../ install
10    root$ make -C .. rmmod (had a number of errors because of stk1160 so unplugged EasyCap and re-ran, lots of errors - see below)
11    tried to modprobe cx23885, but got "invalid agrgument"
12    tried to reboot, but ls /dev/video* showed nothing.

Following are the errors from make -C .. rmmo.

The ImpactVCB-e card is installed. Should I unplug it before doing point 11?

Thanks

Steve

You may have to do a 'depmod -a' here. Try that first.

Somewhat strange error message. Does 'dmesg' give you any useful info?

Regards,

Hans

I get this:

image@image-H61M-DS2:~$ dmesg | grep -i cx23885
[   13.237914] cx23885: disagrees about version of symbol altera_init

image@image-H61M-DS2:~$

There were altera_init issue in the dump I gave you earlier too.

Regards,

Steve.

Hi Hans,

I tried that. It worked fine. No more error messages from

make -C .. rmmod

However this error message is the same. It actually:

ERROR: could not insert 'cx23885': Invalid argument
If I do a search for cx23885.ko, I find one that I have just created. If I cd to that directory and modprobe ./cx23885 I get no error messages.

However, lsmod | grep -i cx only finds cx2341x.

Dmesg continues to give:

[   13.237914] cx23885: disagrees about version of symbol altera_init
[   13.237917] cx23885: Unknown symbol altera_init (err -22)

altera_ci.ko is the only other file in /lib/modules/3.11.0-18-generic/kernel/drivers/media/pci/cx23885/*

Regards

Steve

Is it a regression issue?

https://github.com/ljalves/linux_media/issues/2#issuecomment-23365778

I'm on 3.11.0-18.

Regards

Steve.

Try this:

find /lib/modules/uname -r/|grep altera

If you have duplicate altera-stapl.ko files, then that might explain it. In that case remove the older module.

It does install correctly for my 3.13 kernel.

Regards,

Hans

Hi Hans,

Thanks for this.

There are indeed duplicates. I removed the older one and dmesg went wild :) Dump follows at end of email.

However looking at the tree structure I have to say I don't understand it. Firstly there seem to be two equivalent branches in /lib/modules/:

1) drivers/linux/drivers/misc/altera-stapl/

and

2) drivers/misc/altera-stapl/

Before I do the patch and build, altera-stapl.ko is in 2) but the make install puts the new version in 1).

If I delete the version in 1), I delete the effects of the patch, if I delete the version in 2), I get the dump below.

I upgraded to 3.11.0.19 and reinstalled linux tv, but same effect.

Note that the dump here gives err 0, but the original error was err -22. Is -22 significant, does anyone know what it means?

Also, there is an altera.h of size = 0 in lib/modules/...../include/config/spi but as it is not duplicated on linuxtv/media_build I imagine it doesn't affect the compile.

There has been quite a bit of discussion about this error in previous releases and patches have been applied (as I'm sure you saw). It seems we still haven't quite got to the bottom of it as it is still reappearing. I think it would be quite useful to put it to bed once and for all.

Thanks so much for your help.

Regards

Steve.

image@image-H61M-DS2:~/media_build$

Weird. It looks like media_build misinstalls this. If altera-stapl is in the wrong place, then I suspect the other modules are also in the wrong place and thus duplicated, which will cause all the things you see below.

Which distro are you using?

Anyway, I would recommend that you make a safety copy of your modules first (just in case :-) ), and then move all the newly install modules to the right place.

Regards,

Hans

Yeah, I generally recommend that in such cases you just "rm -rf /lib/modules/uname -r/kernel/drivers/media" before running "make install", so you know you're in a clean state (make a backup copy first though, just in case). This avoids having to figure out which driver moved and the old version of which didn't get deleted.

Hi Guys,

Well after much soul-searching about how to find out how many files were in the wrong place, it turns out it was JUST one: altera-stapl.ko

It was the only one in drivers/linux/drivers/misc/altera-stapl/. When I moved it everything fell into place the card was detected.

So this is the solution to issue one.

My distribution is Debian (Kubuntu 13.10) and this appears to be the only file that goes in the wrong place. How do I log this as a bug?

I set up a video feed and the video was detected.

Results follow in next email.

Regards

Steve.

Hi Guys,

Ok, here is the first issue:

1) I have a 640x480 video feed which displays appropriately through stk1160, but only displays at 320x240 in ImpactVCBe.

In fact this is the same issue I had last year with:

echo cx23885 card=5 | sudo tee -a /etc/modules

Is your card giving you 640x480?

Thanks

Steve.

For no good reason AFAICT the initial resolution is set to 320x240. But you can just set it to 640x480 (or more likely, 720x480 for NTSC or 720x576 for PAL):

v4l2-ctl -v width=640,height=480

Regards,

Hans
