Syntek USB 2.0 Video Camera
===============
Sources: Download http://sourceforge.net/projects/syntekdriver/
Swivel: http://sourceforge.net/projects/syntekdriver/forums/forum/616182/topic/2879518
Post-2.6.38 doc: http://doc.ubuntu-fr.org/syntek
Required files:
Media:usyntek.tar.gz Media:Makefile-syntekdriver.bin
Current "dirty" method, as from ubuntudoc.fr:
Specific hack for kernel version >=2.6.38 Download, blindly trust and pray the above Media:usyntek.tar.gz file doesn't harm your machine. You should not download and use such a file from an unknown person, really. It's only the mod'ed sources for the driver, so please unpack, and browse carefully before use.
CD to the unpacked ./syntek/driver/ in a terminal;
To compile, do:
# make -f Makefile-syntekdriver # make -f Makefile-syntekdriver install # modprobe stk11xx
Test
$ lsmod | grep stk $ vlc v4l://dev/video0 --noaudio OR $ mplayer tv://dev/video0
Old README from sourceforge - dead as of 2008, 2010 at the latest:
Note : The syntek USB 2.0 video camera driver for DC-1125 ans STK-1135 is currently being developed on Linux. This driver can do damages. Use this driver only if you know what you are doing.

1. Requirements
Kernel 2.6.18 or higher Doxygen to compile the documentation
2. Compilation
2.1 Documentation
To build documentation : $ make -f Makefile.standalone doc $ make -f Makefile.standalone cleandoc
2.2 Kernel module
To build the kernel module :
$ make -f Makefile.standalone
or
$ make -f Makefile.standalone driver
$ make -f Makefile.standalone clean
3. Installation
TODO...
4. Usage
4.1 Option "fps" module
The syntek module waits the option "fps" (10, 15, 20, 25, 30) : $ modprobe stk11xx fps=30
By default, the fps is set to '25'.
4.2 Options "hflip" and "vflip" module
The syntek module waits the options "hflip" and "vflip" (values are 0 or 1): $ modprobe stk11xx hflip=0 vflip=1
By default, the hflip and vflip are set to '1'.
4.3 Options "contrast", "colour", "brightness" and "whiteness"
The syntek module waits the options "contrast", "colour", "brightness" and "whiteness" : $ modprobe stk11xx contrast=0x7F00 colour=0x7F00
By default, the value of these options is set to '0x7F00'.
4.4 Use the "sysfs"
In the directory : /sys/class/video4linux/videoX (by sample video0), you can read and write some parameters : $ cat hflip $ echo 0 > hflip
To display informations about driver :
$ cat informations
5. Status
The kernel module is currently being developped.
The driver supports several webcam models : - 0x174F:0xA311 : Quiet good supported (developper's model) - 0x174F:0xA821 : Supported (only the video stream) - 0x174F:0x6A31 : Supported (only the video stream) - 0x05E1:0x0501 : Like '0x174F:0xA311' (it's the same model)
To increase the support, I need some help... Or somebody gives me the webcam !
6. Test experimental
To build and load the driver, follow the steps :
$ make -f Makefile.standalone clean $ make -f Makefile.standalone $ modprobe videodev $ insmod stk11xx.ko
To test the driver with the V4L v1 API (map methode) :
$ camorama -D --width=640 --height=480
To test the driver with the V4L v1 API (read methode) :
$ camorama -D -R --width=640 --height=480
To test the driver with the V4L v2 :
$ xawtv
To use mplayer / mencoder :
$ mplayer tv:// -tv driver=v4l:width=640:height=480 $ mplayer tv:// -tv driver=v4l2:width=320:height=240:fps=25:outfmt=rgb24:device=/dev/video0 $ mplayer tv:// -tv driver=v4l2:width=320:height=240:fps=25:outfmt=yuy2:device=/dev/video0 $ mplayer tv:// -tv driver=v4l2:width=320:height=240:fps=25:outfmt=uyvy:device=/dev/video0
$ mencoder tv:// -tv driver=v4l:width=640:height=480:outfmt=rgb24:device=/dev/video0 -nosound -ovc lavc -o out.avi $ mencoder tv:// -tv driver=v4l2:width=320:height=240:fps=25:outfmt=rgb24:device=/dev/video0 -nosound -ovc lavc -o out.avi
7. Debug
7.1. 'lsusb' output
[root@Dahlia driver]$ lsusb Bus 002 Device 002: ID 046d:c047 Logitech, Inc. Bus 002 Device 001: ID 0000:0000 Bus 005 Device 001: ID 0000:0000 Bus 004 Device 002: ID 0b05:1712 ASUSTek Computer, Inc. Bus 004 Device 001: ID 0000:0000 Bus 003 Device 001: ID 0000:0000 Bus 001 Device 004: ID 174f:a311 <== Our Webcam Bus 001 Device 001: ID 0000:0000 [root@Dahlia driver]$ lsusb -d 174f:a311 -vvv > lsusb.txt
7.2. USB logs from Windows
There is 3 USB logs useful : - Log 1 : when you plug your webcam - Log 2 : when you run VideoView.exe (with the default settings) - Log 3 : when you run VideoView.exe, then change the resolution to 1280x1024
7.3. USB logs from Linux
Use the kernel module usbmon (enable option debugfs in the kernel)
7.4. Enable module traces
You can enable : CONFIG_STK11XX_DEBUG and CONFIG_STK11XX_DEBUG_STREAM
8. Licence
The kernel module is distributed under the licence GPL.
