Hi,

I'm trying to write a driver for a webcam based on Topro TP6801/CX0342
(06a2:0003). My first attempt (needs gspca) can be found on:

http://www.control.lth.se/user/andersb/tp6800.c

Unfortunately the JPEG images (one example dump is in
http://www.control.lth.se/user/andersb/topro_img_dump.txt), seems to be bogus,
they start with (data is very similar to windows data):

00000000: 0xff,0xd8,0xff,0xfe,0x28,0x3c,0x01,0xe8,...
...
0000c340: ...,0xf4,0xc0,0xff,0xd9

Anybody who has a good idea of how to find a DQT/Huffman table that works with
this image data?

Best regards

Anders Blomdell

Hi Anders,

Thomas Champagne (See To:) was also writing a driver for this webcam.
Maybe you may merge your codes...

About the JPEG images, the Huffman table is always the same and the
quantization tables depend on the compression quality.

>From the USB trace I had from Thomas, I saw that:

- when a packet starts with '55 ff d8', it is the first part of the
  image. This one should start at the offset 8 of the packet.

- when a packet starts with 'cc', it is the next part of the image.

In the function pkt_scan, when finding the image start, you must add
the JPEG header: 'ff d8', DQT, huffman table, SOF0 and SOS.

As we don't know the quality used by the webcam, in my test repository,
I added a control for that: the JPEG header is created at streamon
time, and the quantization tables may be modified by the control on the
fly (have a look at stk014.c for an example).

This solution is not the right one: the JPEG quality must be set by the
VIDIOC_S_JPEGCOMP ioctl instead of VIDIOC_S_CTRL. I think I will update
the concerned subdrivers next week.

BTW, don't use the video4linux-list@redhat.com mailing-list anymore: all
the video discussions are now done in linux-media@vger.kernel.org.

Best regards.

You can search in the Windoz binary driver for JPEG markers (FFxx). 
Maybe, you can find a basic DQT/Huffman table in there.

Thomas, if you have DQT/Huffman tables for this camera, please drop me a 
note.

>

Does this mean that it's the same for all JPEG images or only for one 
camera?

If it's the same for all images, it should mean that I have a way to 
determine how much I have to chop off after the 0xfffe tag (no illegal 
huffman codes -> possibly chop at the correct position).

Comments anyone?

This is even in the docs, and is implemented in the driver.

OK, will see if I can find the DQT (and possibly the Huffman table) in 
the windows driver (as suggested by Thomas Kaiser).

I'll look into that monday.

OK, so Google hit http://www.linuxtv.org/v4lwiki/index.php/Main_Page is 
no hit then...

As per definition of JPEG, the Huffman table is always calculated 
especially for each picture to get the best compression. Thus the 
Huffman table and the DQT has to be in the JPEG stream like you see on 
JPEG picture on your HD.
With webcams, it is a bit an other story. The webcam hardware is usually 
not powerful enough to calculate the Huffman table for each frame. 
Therefor a static Huffman table is used. This Huffman table should fit 
more less to the image the camera is producing. With the drawback that 
we cannot achieve the highest compression possible. On the other hand 
the Huffman table is always the same the cam has not to send this in the 
video stream and the stream has less overhead.

In short, the Huffman table is always the same for a given webcam.

I don't think 0xfffe is a valid JPEG marker. 0xfffe is a comment marker 
and the next 2 bytes after this markers tells the length of the comment 
(including the two length byte). So, your comment would be 10300 Bytes 
long. I don't think that such many Bytes are used for a comment when 
they try to have as less as possible overhead.
I think 0xfffe is the start of the compressed data stream and has 
nothing to do with JPEG markers.

I already explained it:

- when a packet starts with '55 ff d8', it is the first part of the
  image. This one should start at the offset 8 of the packet.

In gspca, the file "jpeg.h" contains all the material to build a
complete JPEG header. With the new mechanism of my test repository, you
must:

- at streamon time (function sd_start):
	- allocate a buffer for the JPEG header,
	- set the resolution and number of samplesY (0x22 or 0x21) by
		the function jpeg_define,
	- set the quantization tables by the function jpeg_set_qual,
	  the quality being in percent (15..95).

- when getting the start of a new image in sd_pkt_scan, add the JPEG
  header as the first packet.

- at streamoff time (function sd_stop0), free the JPEG header.

- on VIDIOC_S_JPEGCOMP (function sd_set_jcomp which you must create),
  redefine the quantization tables by jpeg_set_qual.

Cheers.

Hi Anders and others,

I have already tried to create a module for my webcam (Topro TP6800).
It have the same usb id (06a2:0003).
But I have the same problem as you about the image data. I don't know
what is the comment tag (FF:FE). I tried to skip the tag or to skip
the comment with the length after this tag but the image is never
good. I don't know where start the image. If you want an example of
the bad result you can download this image :
http://lafeuil.free.fr/webcam/images/1.jpg
So, I am also in the dark.

If you want to take a look to my code, you can download this file :
http://lafeuil.free.fr/webcam/tp6800.c

If somebody have an idea how can I transform the data, Tell me !

Good luck
Thomas Champagne

Hi Thomas and Anders,

I add a look at your image (the samplesY is odd) and also at some other
ones in the USB snoop you sent me, and, yes, the exact start and the
parameters of the image are not easy to find.

I tried to ignore the first 7 to 25 bytes without any success. The
image samplesY should be 0x21 (it is not 0x22 - can it be something
else?).

If the webcam can record photos or if the MS-win driver could output
raw images, it would help. Is it possible?

The last solution is to trace the tiny JPEG decoder changing the input
offset until it does not see error of the Huffman code anymore...

Cheers.

Thanks for trying, though...

Beats me.

Don't know. The driver states 'TWAIN/VFW/Direct show' compatibility, but if any
of those can be used to get RAW images (do you by this mean JPEG as it comes
from the camera, or truly RAW images [RGB/YUV]).

> The last solution is to trace the tiny JPEG decoder changing the input

Where can I find that?

I have also tried to backtrack through the distributor chain in order to try to
get technical info, since TOPRO doesn't seem to answer emails from ordinary
users. Will see if that gives any results...

Best regards

Is the 5x directly following the FFD9 (in my camera, the next frame [55] is in a
new ISO frame)?

I have only seen ISO frames starting with 55 (new frame) AA (abort frame) CC

Or perhaps JPEG encoded data.

Since the manual states that the chip does JPEG compression, and the frames are
significantly smaller than 640*480 and varies in size, I expect it to be in some
compressed format, and so far I expect JPEG (but with unknown Huffman/DQT tables).

It would be interesting to know if somebody well versed in windows programming
could write a program to get JPEG frames out of the driver directly (provided
this is possible of course), if the image part of such a frame matches the data
seen on USB, we would then have the Huffman/DQT tables.

At the moment I'm stuck, since I see no way to find out what Huffman/DQT tables
that are used.

Will do (TP6801 manual), also available at:

What do you base that on (just curious, I'm not in a position to argument)?

What makes you so sure? FF00 perhaps?

Hmm, perhaps setting all entries in the gammatables to the same value would give
some useful information then. See more below...

Looks like 17 DQT tables to me, if one assumes that the description for register
79 (QUALITY):

  JPEG compression quality factor 0 ~ 31
    0: good quality
    15: smallest size
    16 ~ 31: ultra fine quality

can be interpreted as that there are 17 different quality levels, that should
mean that we have some information. If we then set the gammatables (Bulk-Out
with prefix) to constant values, we should know what data goes into the Huffman
encoding, which might give some additional information.

Don't know, but it's new data to chew on...

When I set the RGB/YUV gains to zero, I get:
> 5a ff d8 ff fe 14 1e 00 fd f5 45 7e e8 f8 b8 df 49 57
     ff d8 ff fe 28 3c 01 fc ff 00 45 66 9a 69 a2 95 4d 2a 12 d1 00 a2 b4

followed by a big number of repeated (0x152c bytes total):

  02 8a 00 a2 80 28 a0 0a 28

and ending with:

  02 8a 00 a2 80 ff d9

In binary the repeating sequence can be diveded in half:

  0000 0010 1000 1010 0000 0000 1010 0010 1000
  0000 0010 1000 1010 0000 0000 1010 0010 1000

Which approximately adds up to 1200 repetitions of this bitpattern 2*(0x152c -
23)/9.

And a 640*480 image divided in 8*8 subframes gives (640*480/(8*8)) 1200
subframes, so now the question is how much info about the Huffman table this
gives us?

When I change the quality setting of the camera, the bitpattern changes, but
size stays approximately the same, here follows the start of the frames at
different quality settings. Notable facts:

  1. Byte 6 seems to be currently used quality setting
  2. Byte 4 & 5 are exactly twice as big as in Thomas dump, could it be related
     to size?
  3. Quality settings 0x10 to 0x1f seems to generate the same bit-patter, which
     indicates that the file Thomas found might be the DQT, now the quistion is
     if my dumps together with those tables are enough to determine the huffman
     table used (hopefully the same for all quality settings)

That is more less the same sequence I get when I do my saturation stuff 
(white picture) :-) . As of coincidence, the same Bit pattern is found 
in the PAC7311 when I do the saturation stuff. And I know the PAC7311 
stream. That's the reason why I wrote I am 100% sure that this is JPEG 
;-) PAC7311 has a special marker between each MCU which has to be 
removed. I don't see such thing in this stream. So it must be pure JPEG.

I think nothing :-( , but you found the MCUs :-) As it looks quite the 
same as on the PAC7311, why not just try the Huffman table from the PAC7311?

The frame header on the PAC7311 is ff ff 00 ff 96 62 + 1 Byte MCU Marker 
44, then the JPEG data starts. Look at this:
ff ff 00 ff 96 62 44 f7 ca 28 01 10 a2 80 11 0a 28 01 10 a2 80 11 0a 28
Side note: the first 01 10 is the MCU marker 44 embedded in the Bit stream.

TP8610, first few Bytes with frame header:
5a ff d8 ff fe 14 1e 00 fd f5 45 7e e8 f8 b8 df 49 57 ab 0a 28 73 0a 28 
02 8a 00 a2 80 28 a0 0a

Therefor I think this is the start of the stream:
ab 0a 28 73 0a 28 02 8a 00 a2 80 28 a0 0a

Don't know why we have 73 in between :-(

Hope this one helps....

Thomas

Which seems to be encoded in the stream and not defined in the sourcecode (but
I'm tired, so I might well be wrong). Do you think you could extract it somehow?

I think it should be in the gspca source or in the v4l_library? I didn't 
follow gspca code and v4l_library code lately. Anyway PAC7311 is working 
AFAIK.

I'll check and try.

Thanks for trying though.

I tested some more, and by starting at offset 7 (based on that ff00 indicates
jpeg stream, and that byte 8 differs between quality 1 & 2, [byte 7 follows
quality])

  Size=152d, quality=1
  ff d8 ff fe 28 3c 01 fc ff 00 45 66 9a 69 a2 95
  ...
  Size=152a, quality=2
  ff d8 ff fe 28 3c 02 f9 55 15 29 a5 52 95 34 a8

I get img0 with the DQT you found on your installation disk, while img1 is what
you get with the standard DQT. Could it be that yuv=0,0,0 implies a black image?
Length is still bogus though, and with yuv != 0 I still get garbage, so I assume
there is some problem with the huffman coding still!

I guess what I have to do, is to transform a yuv=0,0,0 image using the 17
different DQT tables you found and try to generate a huffman table that matches
that data and the 17 different samples I have (of course this table will have
unknowns, but it might be a starting point).

Hello Anders

What is the resolution of your black frame?

I changed the component subsampling to 4:2:0 and the image size to 
320x240. No your black frame looks OK :-)

The black one is frameA-1.jpg and I attached my almost white one 
frame5-1.jpg.

Hello Anders

Good news, I could decode a frame which I extracted from the usbsnoobs I 
did :-). See attached picture frame3-03.jpg. It uses the quality 0.

Your black frame you sent me gets now correctly decode, too (frameA-01.jpg)

I found the Huffman table in the Windoz driver file (TP6810.sys) at 
offset 0x2a59c. The QTable which I found in a text file on my Windoz box 
can be found in this driver file, also.

I attached some binary files which I used to build the 2 attached jpeg.

For example use:
cat FFD8-Q0-320x240.bin huffman1.bin FFDA.bin frame3-3.bin >frame3-03.jpg
to make the picture frame3-03.jpg.

This information should the cam get going in Linux ;-)

Happy Hacking,

Thomas

PS: I sent this to the linux-media mail list, because somebody else is 
interested about this information, too.

Just some comments about the observation you made on the frame header:

ff d8 ff fe 28 3c 01

- Byte 6: Yes, it is the current quality setting
- Byte 4 & 5: I think it is related to resolution. My snoops were done with 320x240 (0x141e) and Anders were made with 640x480 (0x283c), twice as big!
- The rest is static

Youhhhouuu ! You are the King of the snoop ! How did you find an
huffman table in the middle of a file ?
But, I don't have received any file with the mail ? Have you correctly
attached the files in the mail ?
Thank you again for this good news !
Thomas

OK,

Things are looking brighter, I can capture single images with a slightly
modified uvccapture and streaming with mplayer (with bogus colors, but
identifiable image data)

ucview doesn't work though; complains on huffman, but I'll look into colors first...

Regards

/Anders

Hello.

Today I became to be (un)happy owner of 06a2:0003 device. I found nice
discussion here in this list, but I've just subscribed to it.
So, I have some free time to test and improve existent code. If I will
be helpful, tell me, please!
(I'm using Fedora 9, but I could compile any additional driver for
that 2.6.27.15 kernel)

New version attached, handles both 640x480 and 320x240, corrected gamma table.

Seems to work OK with mplayer, vlc and https://launchpad.net/python-v4l2-capture

 vlc v4l2://dev/video0:width=320:height=240
 vlc v4l2://dev/video0:width=640:height=480

Jean-Francois: feel free to add this to gspca if it lives up to your standards,
otherwise tell me what needs to be changed.

Best regards

/Anders

Hi Anders,

Before submitting a driver, please make sure it passes the
checkpatch.pl script found in the linux/scripts/ folder.
When I checked the tp6800.c file I got about ~4300 errors.
This is due to that the file isn't using the indentation used by
code in the linux tree.

If you first run the Lindent script (found in the same folder) about
23 errors pop up that need to be corrected. Beware though that
Lindent sometimes screw up lines so manual inspection of the code is
needed.

Best regards, / hälsningar,
Erik

Hi Anders,

Your driver seems fine, but, to add it to gspca, I need a full patch,
i.e the diff of the source, Kconfig, Makefile, webcam reference in
gspca.txt (linux/Documentation/..) and your SOB (signature).

You should also ask Mauro to add you as a maintainer with a diff of the
MAINTAINERS file from the last Linux kernel.

Cheers.

Hello Anders

I found a small time for testing your code. But your code doesn't work
with my webcam. :-(
I think it doesn't have the same sensor. Can you add in the sd_init
method the check of the sensor id ? You can adjust this patch with
your sensor id :

Please, tell me what is your sensor id.
