Quickstart
|
||||
==========
|
||||
|
||||
Ubuntu
|
||||
$ sudo apt-get install libglib2.0-dev libusb-dev build-essential gcc automake mercurial
|
||||
$ hg clone http://bitbucket.org/ahixon/r5u87x/
|
||||
$ cd r5u87x
|
||||
$ make
|
||||
$ sudo make install
|
||||
$ sudo r5u87x-loader --reload
|
||||
|
||||
The loader will automatically be run on boot when it detects your webcam.
|
||||
|
||||
Installation from source
|
||||
========================
|
||||
|
||||
Simply install the dependencies required above on your system, then run
|
||||
'make'.
|
||||
|
||||
Now you can proceed to installing the tool system-wide:
|
||||
# make install
|
||||
|
||||
If you have udev installed, your system will automatically load the firmware
|
||||
to the camera, and then reload the uvcvideo module at boot time.
|
||||
|
||||
Please note that the loader is installed system-wide as 'r5u87x-loader', but
|
||||
compiles as just 'loader'.
|
||||
|
||||
You can either reboot or follow the instructions below.
|
||||
|
||||
Usage
|
||||
=====
|
||||
|
||||
To upload the firmware to your camera, simply run (as root):
|
||||
# loader --reload
|
||||
|
||||
`# ricoh-webcam-loader`
|
||||
|
||||
Do note that this only lasts while the camera still has power to it. Shutting
|
||||
down and starting up again will cause the camera to lose its state. Rebooting,
|
||||
however, won't.
|
||||
|
||||
If your camera appears to be playing up, you can try forcefully resetting it:
|
||||
# loader --force-clear
|
||||
|
||||
`# r5u87x-loader --force-clear`
|
||||
|
||||
There are also useful arguments for testing, see docs/extracting_ucode.txt

Bugs
|
||||
====
|
||||
|
||||
The following issues are known already, so please *do not* report them (you
|
||||
can, however, subscribe to any of these tickets):
|
||||
* Broken pipe (code 32) - http://www.bitbucket.org/ahixon/r5u87x/issue/6/
|
||||
* Distorted/stripy video - http://www.bitbucket.org/ahixon/r5u87x/issue/17/
|
||||
* HP Pavillion dv9000 or similar aren't detected (make sure you uncomment
|
||||
only *ONE* device, not both) - http://bitbucket.org/ahixon/r5u87x/issue/26/
|
||||
* Upside down video - http://www.bitbucket.org/ahixon/r5u87x/issue/7/
|
||||
|
||||
Please note WDM devices WILL NOT WORK.
|
||||
You can check what type of model you have by looking at the model chart found
|
||||
in docs/model_matrix.txt. If you're running a WDM based device, you can try to
|
||||
look on the internet for a patched version of r5u870, however it will probably
|
||||
not work with more recent kernels.
|
||||
|
||||
You should also register, otherwise you may not get notifications of any
|
||||
replies to your bug.
|
||||
|
||||
Report any bugs by creating a new ticket at
|
||||
http://www.bitbucket.org/ahixon/r5u87x/issues/new/. If possible, make sure
|
||||
that the bug you have hasn't already been reported by searching the issue list.
