SANE sq930x vidcam backend ( sq930 sq930b / sq930c ) + sq930 kernel module

SANE sq930x vidcam backend (sq930b/c) + sq930 kernel module

Main Index, webcam info, Info, links, documents, Progress: sq930 kernel module, SANE sq930x backend, Download, To Do list

Goal for this page is to collect data about the sq930b/c usb bridge (webcam) and to give information
about the SANE sq930x Vidcam backend and sq930 kernel module.
Some parts of the Sane stv680 backend are used for this sq930x backend.

For using this pre alpha SANE sq930x backend the following files need to be patched/placed:

sane backends (use SANE version 1.0.19 or higher):
placed in backend directory (1.0.18): sq930x.c, sq930x.h and sq930x.conf.in files.
placed in doc/descriptions directory: sq930x.desc file.
patched in backend directory: dll.conf.in (add: sq930x)
patched configure.in (add to list BACKENDS: sq930x)

Run: autoheader
autoconf
Makefile patches:
For 1.0.19 or older
patched Makefile.in: backend/Makefile.in
add lines after "# We must not build SANE backend libraries ..":
libsane-sq930x.la: ../sanei/sanei_constrain_value.lo
libsane-sq930x.la: ../sanei/sanei_usb.lo
Check/add by DISTFILES: sq930x.c sq930x.h sq930x.conf.in
For 1.0.20 or newer
patche Makefile.am backend/Makefile.am
doc/Makefile.am
add lines for sq930x, use as example the stv680 lines
Run: automake

export BACKENDS=sq930x Only sq930x backend will be compiled

Run "./configure --sysconfdir=/etc --prefix=/usr --mandir=/usr/share",
"make", and "make install" (as root) as usual.

sane-frontend (use SANE version 1.0.14 or higher):

Use "export SANE_DEBUG_SQ930X=255" to enable debugging.
Use "export SANE_DEBUG_SANEI_USB=255" to enable debugging for sanei usb functions.
Use "export SANE_DEBUG_XSCANIMAGE=255" to enable debugging for xscanimage functions.

Check file permisions from (for example 0666): (hotplug) /proc/bus/usb/0xx/0yy or
(udev) /dev/bus/usb/0xx/0yy

If you want to add your device, just add code until the backend works.

Reference: backend-writing.txt

At this moment there are two frontends which can be used with the sq930x backend:
1. xcam: xcam -B for display (no streaming video (SANE bugreport 300832) only snapshots in
display and save to file is possible).
If a modified version is used, only streaming frames is possible
remove first "stop_camera ();" line in routine "input_available".
2. scanimage: for writing in batch mode to files (files can be one file
each time overwritten or each time a frame is written to a new file).
scanimage -B -d sq930x:libusb:001:002 --batch=out.ppm --batch-count 5 --mode "Color RGB"
for different files use =out%d.ppm
3. saned: not tested yet.
4. scanadf: not tested yet.
5. USB network? see usbip

Using other frontends will be a problem, no idea if for example
writing a gstreamer-sane plugin will be a lot of work and/or difficult.
Another solution could be to use a frontend which can read the file from
scanimage which is refreshed at a rate of .. fps.
Some other idea's are on the next pages:
stv680 userspace program with sdl gui
pccam880 userspace program with v4l interface
Python sane example
