• [mac, uvc-ctrl] uvc-ctrl 1.02alpha out..

  update: regarding the iSight, to get the it into uvc-ctrl menu it has to be active..
  
  update 2: This was originally the release announcement for 1.0a, but i did some minor changes that i realized fixed some really annoying things in that version so i uploaded the new one (1.02a) and just replaced the download link here.. if you’re one of the first five to download the 1.0a version, i’m sorry!
  
  here’s the new alpha version of uvc-ctrl, it looks pretty much as the screenshots in the previous post. function-wise it doesn’t differ much from the last one but it now comes with a native gui localized in english and swedish and is completely dependency-free. note that it’s a status-bar app so no windows are displayed until you select a camera in the menu. there are still some functions missing, most notably the cam-profiles.. also, i’ve only had the chance to test it on 10.6.8. if anyone would like to report success/fail on other os x versions that would be super!
  since this is a complete rewrite any and all bug-reports are very welcome, either to sluggo@dm9.se or in the comments below. It would be great if the they included your os x-version, any messages from the Console-app in the Utilities folder (you can filter with the phrase se.dm9) and what led up to it.
  lastly, since i wouldn’t be able to draw a stick-figure if my life depended on it there’s no icon!

• [mac, uvc-ctrl] new, mainly bugfix version of uvc-ctrl

  new version out
  not much done but since i got rid of the most annoying thing i figured i’d release it anyway.. here’s what’s done

  • could not claim interface: access denied error fixed. settings are still reset when some progs are started but they can now be set whilst running e.g. skype.
  • show configuration works again.
  • power line frequency control (manual 50/60Hz anti-flicker setting) added.

  This version is also compatible with Klaus’ gui.

• [mac, uvc-ctrl] uvc-ctrl gui!

  Klaus has written a gui for the latest version of uvc-ctrl! to use it all you have to do is place the uvc-ctrl in the same folder as his app and you can point-and-click-control your uvc cam. if you wish to bundle uvc-ctrl and Klaus’ gui you just copy it into the app. the easiest way to do that is by unpacking uvc-ctrl and uvc-ctrl-GUI in your home-folder, start the terminal (Applications > Utilities > Terminal) and type

  mv uvc-ctrl uvc-ctrl-GUI.app/Contents/MacOS/

  and then hit enter.
  Thank you Klaus for you awesome work!

  note libusb is still required.

• [mac, uvc-ctrl] new version of the uvc-controller

  new version out
  gui available
  
  since people actually seemed to like this and i won’t have time to fix a gui for the new version for some time i’ll publish it without gui.
  the new beta fixes some bugs (especially the white balance one) and adds some feats.. no changelog available but here’s what you can get/set if your camera supports it: auto-focus, absolute focus, relative focus, auto-exposure, absolute exposure, absolute iris, relative iris, auto-white balance temperature, absolute white balance temperature, brightness, contrast, gain, saturation and sharpness.
  note that the argument order has changed since the last version, think “get/set <value> of <function> on <cam>”. also included the source this time!

  the binary included is “universal” (i386/x86_64) and have been tested on both os x 10.6 and 10.7 (thanks to Arvid). the source has also been compiled on freebsd9. it does not require python as that was only the gui. it does however require libusb.

  known bugs (thank you Matthew and F-red for the reports)

  • interactive session can’t take negative values
  • auto-exposure value description in wrong order
  • show configuration segfaults

  update thanks to Klaus’ report it seems possible to fix the problem with programs resetting settings made by uvc-ctrl. if you have this trouble: try starting the program that resets your settings, from within it switch to your iSight, update the settings you want with uvc-ctrl on your other cam and then switch back. your settings should now still be in place.

• [mac, uvc-ctrl] uvcc: uvc-controller app, alpha version out

  new version out.
  
  
  codename “ugly-code” is out!
  with it you can kill auto-focus/-exposure/-white balance and set the absolute value of these manually on a uvc camera. the gui is really just thrown together and may not recognize your cam if it returns any error in the get-all request of uvcc.app/Contents/Resources/uvc-ctrl. it does however work nicely with the logitech c910 (on both x86_64 and i386 snowy leopards). a screenshot is available in the earlier post about it.
  oh, and i stole the icon from somewhere on the internet.. can’t even remember where!

  note: requires python 2.6, shipped with os x 10.6 – snowy leopard. so if you are running os x 10.5 you can update your python installation, or just wait.. ill get a new, python >= 2.5 version up in a while.

  note 2: found a bug, the auto exposure slide should go from 1 to 8. selecting 0 will cause an error that goes unnoticed by (well, not that unnoticed.. you’ll notice the setting wasn’t saved)!

  note 3: got some reports it isn’t working.. it seems alotta progs that use a webcam resets all settings (and thus turns on auto-whatever) when opened. This may very well be an apple driver “feat” but most people i’ve spoken with says it works well if they turn off the auto-whatever after starting said program.
  btw, beer is good.

• [mac] libusb-1.0.8 package (installer) for os x

  built a libusb-1.0.8 package installer for os x. it’s a universal binary for both i386 and x86_64 archs (“32 and 64 bit”).
  it was built on a snow leopard (10.6) x86_64 machine; haven’t been able to try it on any other version/arch. used the default minimum target setting in packagemaker which was leopard (10.5) and compiled both a i386 and a x86_64 lib and lipo’d them together.
  anyone with a i386 machine and/or other versions of os x are very welcome to report success/fail.
  update: tested and working on i386 snow leopard.
  update2: tested and working in os x 10.7 (Lion), thank you F-red!

• [ocr] gocr in mac os x

  I needed to do some ocr’ing on the mac and figured i’d go with gocr.
  first off i already had libpng, libjpeg and a svn-client installed. if/when you got that covered this is what you can do:
  download tiff-3.9.5 from ftp://ftp.remotesensing.org/pub/libtiff. to build it just unpack and

  ./configure #add --build=x86_64 if you want
  make
  sudo make install

  then download netpbm via svn (for me the super-stable tarball failed, wanting an older version of libpng):

  svn checkout http://netpbm.svn.sourceforge.net/svnroot/netpbm/advanced netpbm

  it has a special kinda, interactive build process

  ./configure # interactive, i could hit enter all the way through.
  make
  # now we first need to build a package
  make package pkgdir=/tmp/netpbm
  sudo ./installnetpbm # also interactive, again i could just go with enter

  now download gocr from http://jocr.sourceforge.net/download.html. this is a simple

  ./configure #--build=x86_64
  make
  sudo make install

  before you can run it you have to add the netpbm dir to your path

  export PATH=/usr/local/netpbm/bin:$PATH

  or if you’re (like me) using tcsh

  set path = ($path /usr/local/netpbm/bin)

  and create a symlink to the netpbm-lib (note that the version may differ for you)

  sudo ln -s /usr/local/netpbm/lib/libnetpbm.11.56.dylib /usr/local/lib

  thats all there is to it, to run gocr with a gui just type gocr.tcl and get your ocr’ing on!
  note that mac os x’s x does not come with xli so there’s no preview available in the gui (aka “show”-btn does not work).

• PyQt4 on mac os x

  Through work i needed to install pyqt4 on a mac os x (snow leopard). So i went to nokia.com and downloaded the latest qt-sdk (sdk: 1.1.3, libqt: 4.7.4), then to riverbank computing and downloaded sip (needed for installing pyqt4) and pyqt4. After installing the standard way i tried a hello world but couldn’t import anything from PyQt4. The module was installed but i could not use it. To make this more google-friendly this is the error i got:

  Traceback (most recent call last):
    File "qt-test.py", line 4, in <module>
      from PyQt4 import QtGui
  ImportError: cannot import name QtGui

  I googled around and found this blog which informed me that when installing PyQt4 you have to explicitly define the path to qmake, site-packages and the arch. if you use python shipped with os x and installed the sdk to its standard path then the command to configure pyqt4 should probably be

  python configure.py -q /Users/<USERNAME>/QtSDK/Desktop/Qt/474/gcc/bin/qmake -d /Library/Python/2.6/site-packages -g --use-arch x86_64

  of course this assumes you have a 64bit os.
