[Linux-uvc-devel] Partial succes with Logitech QC Fusion

[Mikael N. <mi...@na...>]

Hi!

I wanted to report a partial success with my new QuickCam Fusion.

Bus 002 Device 002: ID 046d:08c1 Logitech, Inc.

I'm running Debian unstable, using kernel 2.6.15. 

Compilation works, the module is however installed
in /lib/modules/2.6.15 and not /lib/modules/2.6.15-1-686 as it should,
and it seems to be because Debian stores the EXTRAVERSION in
$KSRC/.extraversion, and I don't really know a general way around it...

Anyway, trying the test program I get

Device /dev/video0 opened: .
Unable to set format: 22.

(22 is invalid argument)

Trying instead using

        fmt.fmt.pix.width = 640;
        fmt.fmt.pix.height = 480;
        fmt.fmt.pix.pixelformat = V4L2_PIX_FMT_MJPEG;

it seems to work: it creates a number of files that "file *" tells me
are JPEG files, but I cannot view them using regular image tools. Tips
for checking them?

I have not gotten xawtv or tvtime to work (xawtv does not like my Xorg
server: XF86DGANoDirectVideoMode, and tvtime complains about not having
studio quality capture). Other tips on applications I should try?

It seems some of my problems might be related to the fact that this
laptop only has USB 1... 

Thanks for the driver, and please let me know if there is something I
could help debug...

Luc,
You only need to pass your output buffer to pic, your input buffer to buf 
if the jpeg data width or height in the header are different from *width and 
*height jpeg_decode realloc the pic buffer (that is why we need **pic) and of 
course change *width and *height so the caller can adjust the output windows 
on the fly.
The routine provide YUYV palette in pic 
Of course you can used it .The original code is from the bootstrap project 
adapted by Suse and by me for the UVC need  (YUYV palette) . It should be 
simple for me to patch the routine to get something shortest and able to 
decode the stream without the huffman table, if you need just tell me.

Why don't used the library from uvcview in utils.c 
int jpeg_decode(unsigned char **pic, unsigned char *buf, int *width,

If you need i can patch this function to accept jpeg data without huffman

Damien told me that Craig Southeren might not want to link against libjpeg. 
You should contact him.

When possible, I'd like to avoid adding workarounds for broken applications if 
the applications can be fixed. That way we won't have to care about backward 
bug compatibility during development.

Ok i've done the code for gnomemeeting (the easy part). I use the YUY2 format
(so it's not very efficient to convert from 1024x576, but i can be use if
another webcam don't support MJPEG stream. I'll send the patch to damien (one
for v4l2 plugin and the other for ptlib). Next step is to add the mjpeg
codec.

I'm attempting to understand what those messages indicate.
One thing I'm not sure I have included is that I'm using the
driver on a labtop, not with an external video card.

You definitely need a library to decode MJPEG. libjpeg might be a bit too big 
to do the job (MJPEG is a small subset of all possible JPEG formats), but 
it's the easiest to use for prototyping.

> I'll look Qt. For now, i only do conversion for the YVY2 format.

The Qt patch I wrote modifies the Qt JPEG codec which uses libjpeg, so you 
will be able to reuse the code in Gnomemeeting. Be careful about licensing 
issues though. pwlib is licensed under the Mozilla Public License 1.1 and Qt 
under the GNU Public License. You can reuse my code in pwlib (I grant you the 
right to use it under the MPL), but not Qt code.

Yes, I've made it to uncompress mjpeg data from an avi, and mov file for my
gallery program (photon) written in python. I known it's not the best langage
to play with bitstream, but it's working i recreate a full jpeg header from
the stream. Else, i dont' known how to decode jpeg data + huffman table

To support ENUM_STD. Only to not return -EINVAL. But it failed somewhere

This doesn't seem related to the driver. The dmesg log seems perfectly normal 
(the 'failed to query control' messages can be ignored for now).

Have you tried to above fixes ? If it fails, can you try to get support from 
tvtime ?

Great news ! Damien Sandras will be happy. I've had a look at pwlib. The code 
is quite clean, but I don't have time to do it myself, so I'm glad you 
offered your help.

> I hope that gnomemeeting is link to the jpeg library or something like that.

I don't think it will be a problem to link to libjpeg (even if Damien would 
rather avoid it if possible). Remember that the MJPEG data doesn't contain 
the Huffman tables, so you need to add them manually (see the Qt patch I 
posted on this list).

I'll see if I can code MJPEG support for Kopete in the not-so-distant future. 
I'm currently working on adding proper controls support to the driver.

Last week, i've made a patch for gnomemeeting, to add a new format to support
the pwc driver, i can add the mjpeg format. I hope that gnomemeeting is link
to the jpeg library or something like that. I've try to modify the driver,
(and a little mplayer) to support uvc but it crash my kernel seems to be the
bug related with ati chipset. I've not retested with a more recent kernel.

Note that one another webcam is using mjpeg, It's the motion eye (meye) on

Don't worry, there's always hope :-)

You can already use your webcam with uvcview or tvtime (if you apply following 
patch to tvtime: 
http://svn.berlios.de/wsvn/linux-uvc/patches/tvtime/tvtime-1.0.2-videoinput.patch?op=file&rev=0&sc=0).

IM support will come (hopefully) soon. It's "just" a matter of implementing 
proper v4l2 and MJPEG support in Kopete and Gnomemeeting. Is there someone 
here who could fix one (or both :-)) of those applications ?

> Finally what can I do or wil be able to do  with my webcam ?

You will be able to use your webcam with all Linux video applications. There 
is no video multimedia framework widely used in Linux applications today, so 
all applications must implement MJPEG support. Maybe KDE4 will fill a big 
hole. But don't worry, Kopete will support your webcam before KDE4. Is there 
someone here already involved with the KDE multimedia development team ? It 
sounds like the right time to raise the video acquisition matter with them.

Hi Simo,

Sorry, I haven't been clear enough. I'd like the output of lsusb -v with the 
CVS version of usbutils (http://sourceforge.net/cvs/?group_id=3581). If you 
can't do that, please cat /proc/bus/usb/your/device and send me the result.

Do you have any experience with device driver development ? The starting point 
here would be to read the UVC spec. You can find a link at the bottom of the 
Linux UVC page.

Could you please send me the whole USB descriptors ? It seems from the snipet 
in your mail that your digital camera works in bulk mode, which is not 
implemented yet (I don't own any bulk mode hardware). If you're interested in 
implementing bulk support, please contact me.

Yes. Unfortunately, neither Kopete nor Gnomemeeting support the image formats 
that your webcam can produce. I expect vlc has the same problems. 
Applications will need to be fixed to handle MJPEG. I had a look at the video 
support code in Kopete, it will probably need to be rewritten.

You're welcome :-)

I've just buy a new webcam : logiteck webcam pro 5000
I've just compile uvcview and its works really well, for the
first time I see the image from my webcam

I've got still a probleme with vlc (VideolanClient) or
