libgphoto2
----------
Hello and welcome to the wonderful world of gphoto! This is libgphoto2, the
successor of gphoto with lots of new features and additional camera
drivers.
If you miss a feature, would like to report success or failure, or have any
questions, please don't hesitate to contact our mailing list.
What is libgphoto2?
-------------------
libgphoto2 is a library that can be used by applications to access various
digital cameras.
For more information on gphoto, see
@URL_GPHOTO_HOME@
There, you can also get information on mailing lists, supported cameras,
and availability of gphoto2. Another source of information is
@URL_GPHOTO_PROJECT@
where you can access our CVS server to fetch the source code of
gphoto2, gtkam and GnoCam (see below).
What is libgphoto2 not?
-----------------------
libgphoto2 itself is not a GUI application, opposed to gphoto. There are
GUI frontends for the gphoto2 library, however, such as gtkam for
example.
libgphoto2 can only talk to cameras the language of those it understands.
That is, if you own a camera that speaks a language that isn't published
anywhere and nobody has been able to figure out the meaning of the sentences,
libgphoto2 cannot communicate with those cameras.
Then, there are cameras supporting the so-called USB Mass Storage protocol.
This is a protocol that has been published and lets you access any storage
device, be it a camera or a disk connected via USB to your computer. As there
are already drivers for this protocol out there, you don't need an additional
library like libgphoto2. The list of camera that use USB Mass Storage is getting
longer everyday, so we won't publish it.
For a more up to date list, you can consult
@URL_DIGICAM_LIST@
Your operating system will tell you about that because it is likely to recognise
the device as a SCSI disk that you can mount (for Linux 'dmesg' will tell you).
Again, those cameras *cannot* be accessed through libgphoto2. Some of them can
be switched to use a different communication protocol and might be in that case
useable with libgphoto2.
Other camera support a protocol called PTP or USB Imaging Devices that has
been developped by Kodak and other. libgphoto2 does support PTP.
Here is a short incomplete list of camera that use this protocol:
* HP PhotoSmart 318, 612, 715
* Kodak DC-4800, DX-3215, DX-3500, DX-3600, DX-3700, DX-3900, MC3 and all the
camera that use Kodak Easy Share(tm) system.
* Sony DSC-P5, DSC-F707, DSC-P30, DSC-P50, DSC-S75, DSC-S85, MVC-CD300
(all need user configuration of the camera)
PTP camera unknown to libgphoto2 can be detected as a generic PTP camera and
will work as is.
You still may try jPhoto <URL:@URL_JPHOTO_HOME@> for ptp cameras
alternatively if libgphoto2 fails.
Platforms
---------
libgphoto2 should compile and run on pretty much all Unix-like platforms.
Additionally, there is a port for OS/2 available. libgphoto2 has _not_ (yet?)
been ported to any operating system from MicroSoft.
How to set up libgphoto2
------------------------
For information on how to set up libgphoto2 and its frontends, see
The gPhoto2 Manual.
It is available at the following places:
- At the gphoto website: @URL_GPHOTO_HOME@
- In the CVS module gphoto2-manual
The gPhoto2 Manual includes information about setting up USB
hotplugging.
If you run into problems, you may also consult the FAQ (also included
in The gPhoto2 Manual).
Frontends
---------
gphoto2 is a command line frontend which is quite powerful,
especially in combination with scripts. See The gPhoto2 Manual
for a short description.
For the GUI lovers, there are for example gtkam (GTK based), and
GnoCam (GNOME). Additionally, there are plugins for other programs
available like kio_gphoto (KDE - Konqueror).
Reporting Bugs
--------------
Every piece of software contains errors and flaws. So does
libgphoto2. When you encounter something that does not work, please do
the following:
1. Find out whether this is a known problem.
2. Reproduce the problem with debug output enabled and the language
set to English, so that the development team will understand the
messages. You can do this by running:
env LC_ALL=C gtkam
if you're using the gtkam frontend or running:
env LC_ALL=C gphoto2 --debug <options>
using the gphoto2 command line interface.
3. Report the problem on the mailing list with the corresponding debug
output if it is small. If it is more than a few kilobytes, please
don't post the complete debug output on the list.
