Re: Lenovo webcam problem which using gspca's vc032x driver

[AceLan Kao]

Dear Jean-Francois,

I use "Lenovo WebCam Center" and "Dorgem" to do the webcam preview
function, there are the following resolution settings
160x120
176x144
320x240
352x288
640x480
Do you need all the resolutions logs?

I try to use "Device Monitoring Studio" to log the USB traffic this time.
You can download the QVGA and VGA USB snoop log and the .INF file from here.

Dear Mauro,

Sure, I'll give you the patches against the V4L/DVB hg tree.
But I think I should come out a conclusion with Jean-Francois, right?

Best regards,
AceLan Kao.

Hello Acelan Kao,

Thanks for the files. I could not look at the dms logs, having no tool
to do. Anyway, the .inf gives the exact USB sequence you set.

I got a return from one guy with the same sensor. He said the driver
works better (with the LEDs), but there are still some frame overflows
and the image is upside down. Have you such a problem?

The sequence for the SXVGA mode (1280x1024) is defined in the .inf. I
extracted it and attached. Does it work for you?

Best regards.

Dear Jean-Francois,

The SXGA setting works for me if the resolution set to 1280x960 and
the image is upside down.
===
        {1280, 960, V4L2_PIX_FMT_JPEG, V4L2_FIELD_NONE, /* mi13x0_soc only */
                .bytesperline = 1280,
                .sizeimage = 1280 * 960 * 1 / 4 + 590,
                .colorspace = V4L2_COLORSPACE_JPEG,
                .priv = 2},
===

And for the QVGA and VGA resolution preview, my display is good, not
upside down.

Best regards,
AceLan Kao.

Dear Jean-Francois,

I would like to know which version of vc032x.c won't make 041e:405b
device display upside down.
And have you let the 041e:405b device owner to test the SXGA setting
and with the 1280x960 resolution? What's the result?

Best regards,
AceLan Kao.

Hi AceLan Kao,

The 041e:405b had a good display with the current version of vc032x
(i.e., including the change 'Webcam 041e:405b added and mi1310_soc
updated').

I've just asked the 405b owners to test the XGA resolution. I'll give
you the results as soon as I will get them.

Best regards.

Dear Jean-Francois,

It sounds like that the Lenovo webcam(0x17ef, 0x4802) sensor and the
0x041e, 0x405b device sensor doesn't be placed at the same direction
and the initial tables seems not so compatible.
Do you think that it would be better to split the code for these two
model of webcams? If yes, I can do some help.

Best regards,
AceLan Kao.

Hi Acelan Kao,

An other guy with the 405b said that all modes were correct but 640x
and 320x upside down.

Looking at the .inf of the ms-win driver, it seems that the Mirror and
Vertical controls exist for the mi1310_soc sensor. May you change them
on ms-win? If yes, may you do a snoop to know which registers do the
job? Then, in the vc032x subdriver, only the set h/v flip had to be
inverted for the 2 webcam types.

Otherwise, I compared the sequences of the ms-win files C0130Dev.inf
(041e:405b) and usbvm323.inf (17ef:4802). The bridge sequences are
close enough, but the sensors sequences are completely different, as if
the sensors were different! So, it is not easy to find how the image
may be upside down...

BTW, I can't read your binary USB snoop. Have you any tool to read it
or may you send me a more readable version?

Best regards.

Hi Acelan Kao,

I got news from a person who has the sensor mi1320_soc and had a
vertical flip problem. She found that the sensor register 0x20 sets the
image flips: bit 0 = vertical, bit 1 = horizontal.

Comparing the sequences of the mi1310_soc, the bit 0 is inverted in the
sxga (0x0303 instead of 0x0302). May you change it and see if the image
is normal? (line ~ 706  {0x20, 0x03, 0x03, 0xbb}, -> 0x03, 0x02)

Best regards.

Dear Jean-Francois,

I put the USB snoop log here
http://people.canonical.com/~acelan/bugs/lp310760/UsbSnoop_{1,2,3,4,89}.log.gz
The utility, USB Snoop, seems to have some problem with the camera
preview utility, so the log may not so complete.
And the dmslog is the USB traffic in binary form, you can read all USB
traffic from dmslog by hexdump the files.

Best regards,
AceLan Kao.
