Hobbynet SANE sn9c10x vidcam backend, under development

Main Index, webcam info, Info, links, documents, Camera info, Progress, Download, To Do list

Goal for this page is to collect data about the sn9c10x pc camera controller and to give
information about the SANE sn9c10x Vidcam backend.
Some parts of the sn9c10x and spca5xx kernel module and some userspace programs are expected to
be used for this backend zie links below. Intention is also to use first the usb bulk read
mode before trying to use the usb isochronous read mode.

For using these pre alpha files SANE sn9c10x backend the following files need to be patched/placed:

sane backends (use version 1.0.18 or higher):
placed in backend directory:              sn9c10x.c, sn9c10x.h, sn9c10x.conf.in,
placed in doc/descriptions directory:     sn9c10x.desc file.
patched in backend directory:             Makefile.in, 
					  dll.conf.in (added sn9c10x)
patched                                   configure.in (add to list BACKENDS: sn9c10x)
patched in tools/udev                     libsane.rules (add line with vid and pid webcam)

Run:                                      autoconf

patched Makefile.in:                backend/Makefile.in 
                                    add lines after "# We must not build SANE backend libraries ..":
                                    libsane-sn9c10x.la: ../sanei/sanei_constrain_value.lo
                                    libsane-sn9c10x.la: ../sanei/sanei_usb.lo
				    Check/add by DISTFILES: sn9c10x.c sn9c10x.h sn9c10x.conf.in
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_SN9C10X=255" to enable debugging.

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.

sane-frontend (use version 1.0.14 or higher):

patched /etc/hotplug/              blacklist (add line with: sn9c102, gspca or spca5xx)

At this moment there are two frontends which can be used with the sn9c10x 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 sn9c10x:libusb:001:002 --batch=out.pnm --batch-count 5 --mode "Color RGB"
   for different files use =out%d.pnm
3. saned: not tested yet.
4. 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.
