Hello
I have a Suyin crystal eye webcam that lsusb give as
Bus 004 Device 002: ID 064e:a103 Suyin Corp
that I have been trying to make work for the last week
to no avail. From what I've read this device
should be no problem. What I am getting is as follows:
Luvcview
--------
1) sh-4.0# luvcview -f yuv
luvcview version 0.2.1
Video driver: x11
A window manager is available
video /dev/video0
Unable to set format: 22.
Init v4L2 failed !! exit fatal
2) sh-4.0# luvcview
luvcview version 0.2.1
Video driver: x11
A window manager is available
video /dev/video0
The green light is on and I have a green screen. The application
is alive until Play with some of the buttons and I messages like
ioctl querycontrol error 22
Set Sharpness down error
ioctl querycontrol error 22
Set Sharpness down error
and then it dies. I have to use kill -9 to terminate it.
Xawtv
-----
sh-4.0# xawtv -v
This is xawtv-3.95, running on Linux/i686 (2.6.29.2)
/dev/video0 [v4l2]: no overlay support
v4l-conf had some trouble, trying to continue anyway
Warning: Cannot convert string "-*-ledfixed-medium-r-*--39-*- .....
ioctl: VIDIOC_G_STD(std=0xbffca810b7d4e000
[NTSC_M_JP,?,?,SECAM_G,SECAM_K,SECAM_L,?ATSC_8_VSB,ATSC_16_VSB,(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null)]):
Invalid argumen
when I click "Grab image (ppm) or "Grab Image (jpeg)" I get:
no way to get: 384x288 16 bit TrueColor (LE)
no way to get: 2048x1572 24 bit TrueColor (BE: rgb)
Uvccapture
----------
sh-4.0# uvccapture -v
Using videodevice: /dev/video0
Saving images to: snap.jpg
Image size: 320x240
Taking snapshot every 0 seconds
Taking images using mmap
Resetting camera settings
ioctl querycontrol error 22
Camera brightness level is -20
Camera contrast level is 0
Camera saturation level is 60
ioctl querycontrol error 22
Camera gain level is -1
Saving image to: snap.jpg
the green light goes on and off momentarily and gives me the picture snap.jpg
but nothing (xv, gimp, mplayer) seems to understand what it is. The first
group of hex chars is
0d 7c 0c 7f 0d 7b 0f 7d
uname -a gives
Linux lapsystemx 2.6.29.2 #15 PREEMPT Sun May 3 08:09:40 PDT 2009 i686 GNU/Linux
dmesg gives:
usb 4-1: Product: Crystal Eye webcam
usb 4-1: Manufacturer: SuYin
usb 4-1: SerialNumber: CN0314-SN30-OV032-VA-R01.00.00
and
uvcvideo: Found UVC 1.00 device Crystal Eye webcam (064e:a103)
input: Crystal Eye webcam as /class/input/input6
usb 4-1: adding 4-1:1.1 (config #1, interface 1)
One thing that puzzles me is that in a letter to Linux-uvc-devel Tue Feb 17
19:26:30 CET 2009, thread titled: [Linux-uvc-devel] Device ID of my UVC WebCam
Martin Koller gives lsusb -v as
Bus 004 Device 002: ID 064e:a103 Suyin Corp
which is the same as my webcam but the devices are not the same. Below I
includea diff of the two listings.
Any help to get this thing working is appreciated.
Regards
