SANE m560x vidcam backend under development

SANE m560x vidcam backend ( development on hold)

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

Goal for this page is to collect data about the m5603c usb bridge and to give
information about the start of writing of a SANE m5603c Vidcam backend. 
No datasheet found on the ALI website, which sensor is present in the Q-TEC webcam 300 USB 2.0?

Q-TEC Webcam 300 USB 2.0: Chip:   Ali M5603C
                          Sensor:  maybe OV7640 or MI0360 or HV7131,

For using these skeleton files SANE m5603c backend the following files need to be patched/placed:

sane backends: 			   (Use SANE-Backens 1.0.19 or higher)
placed in backend directory:       m560x.c, m560x.h, m560x.conf,in
patched in backend directory:      Makefile.in, dll.conf
patched in doc/description:	   m560x.desc
patched in doc directory:	   m560x.man
patched in include/sane directory: sanei_usb.h
patched in lib directory:          sanei_usb.c
patched                            configure.in

system
patched /etc/hotplug/              blacklist (add line with: ????? kernel module)

At this moment there are two frontends which can be used with the m5603c backend:
1. xcam: for display (no streaming video (SANE bugreport 300832) only snapshots in 
   display and save to file is possible).
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 -d m5603cx: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.

Progress
2007	Status: on hold, orking on backend
20-01-2005 21-01-2005 Working on skeleton files m560x.c, m560x.h and m560x.conf.
16-01-2005 m5603c.txt, output from lsusb -vv
15-01-2005 Start of webpage, some test done (lsusb -v, sane-find-scanner -v -v,
           xcam, xawtv, camorama, spacagui, gtkam, gphoto2).
	   No working driver found yet.

TO DO list
1. Work on skeleton files m560x,
2. Waiting for ALI to release some documentation?  :-(
3. Check the sniff-usb commands and info from cdrom.
   For this chip a lot more usb commands are needed compared
   to other webcams, makes it a lot more difficult.
4. No isochronous libusb routine yet to read the frames.
