This release expires August 1, 2008
This should fix one hard-to-reproduce bug reported by Paul where the
video stream would stop after a very long (15 hours) period of use.
It appears that the cause was a hardware problem (or electrical
noise, etc.) on his system which results in an occasional bad packet
being sent -- while this should cause a dropped or possibly bad video
frame, it should no longer cause the driver to stop sending video.
There are no user-visible changes from b13.
Please test with as many applications as possible and let me know of
any problems. Also, let me know of any problems that would prevent
going to a public beta.
Thanks again for your help,
-Steve

Know issues:
1) There is a bug that sometimes creates strangely named files at the
root of your hard drive -- I can not reproduce the problem here, but
they appear to be harmless -- still looking for the cause of this.
2) Motor control not connected to face tracking on UVC Logitech Orbit/Sphere
3) Need a better firmware workaround for 2MP Logitech cameras
----- changes in 1.1.2b14 -----
Don't allow transient errors (bad packet checksum, etc.) to stop USB
isochronous data stream.
----- changes in 1.1.2b13 -----
Fix bugs in FireWire driver instantiation code
Don't match FireWire webcams in Industrial Camera Driver
----- changes in 1.1.2b12 -----
Patch Apple Sequence Grabber Component to prevent SGIdle() from
reentering SGStop() due to a bug in QTKit Image Capture
----- changes in 1.1.2b11 -----
Work around firmware from crash on newer Logitech 2MP cameras,
including the QuickCam Pro 9000 and a few other models, at the slight
cost of slowing down the process of starting the video stream for all
Logitech UVC cameras. (It adds a 1/4 second delay in the right spot
to keep the camera from crashing)
----- changes in 1.1.2b10 -----
Finish Bayer on Intel, switch to 3x3 on both platforms
Fix several bugs related to IIDC controls
Fix enable/disable software zoom (all cameras)
----- changes in 1.1.2b9 -----

Fix FW video freeze (race condition starting stream)
Remove 4088 byte limit for FW Isoch packets
Fix bug in Raw support in Basler 600 series
Increase register access timeout in Sony XCD-SX series
----- changes in 1.1.2b8 -----
FireWire support on Intel (except Bayer and Format 7)
----- changes in 1.1.2b7 -----
restructure FireWire code in preparation for Intel support.
----- changes in 1.1.2b6 -----
bump expiration date (no substantial changes)
----- changes in 1.1.2b5 -----
Fix bug where screen image ends up as two blue squares over some
noise, like this:
<http://www.laservall.com/~francesco.rolando/screenshot_04.jpg>
when video is resized from 320x240 to 640x480.
It may also fix the other reported crash in the Apple RAW codec,
where the top of the stack of the crashed thread looks like this:
>Thread 0 Crashed:
>0 ...ickTimeComponents.component 0x99cffe1c Copy32ARGB32ARGBScale + 156
>1 ...ickTimeComponents.component 0x99cfcc88 RAW_CDDrawBand + 2104

><snip>
Improvements to internal resource loading.
----- changes in 1.1.2b4 -----
Bump expiration date, improved logging.
----- changes in 1.1.2b3 -----
Don't attempt to cache preferences at static init time -- causing
coreaudiod to crash
----- changes in 1.1.2b2 -----
Change Isoc stream logic to be tolerant of Leopard's high USB call latency:
Don't attempt to calculate if we're close to the current time: try a
block of frames and see if we get a TooOld error
----- changes in 1.1.2b1 -----
Bump expiration date to 4/1
----- changes in 1.1.2a47 -----
Fixed the double-install bug -- you should now be able to install
over any version of the driver on any OS version.
----- changes in 1.1.2a46 -----
The new serial number scheme is in place for all drivers (USB Webcam,
FireWire Webcam, FireWire Industrial) so that new purchases will have
a new (1.2) serial number.
Old serial numbers are now properly recognized and supported until we
have an automatic upgrade system in place. (Fixed a bug in a46)
----- changes in 1.1.2a45 -----
I think we have the new serial number scheme is in place and new
purchase with get a new (1.2) serial number -- this release should
work with a 1.1 serial number and 1.2 serial numbers should work with
any previous driver.
I also may have fixed a crash where QuickTime was crashing if fed a
0-length MJPEG buffer.
----- changes in 1.1.2a44 -----
Bump expiration date, fix web page.
<http://www.ioxperts.com/products/webcamx_1.2.html>
----- changes in 1.1.2a43 -----
This release is mostly to bump the expiration date before 1.1.2a42 expires
I'm still working on the purchase and registration code, but made a
number of improvements to the logging code so that it won't log
anything (and fill up your hard drive) if you leave an expired demo
running after the 30 minute limit.
Also, this version is built with Xcode 2.5 (rather than 2.4.1) so
that I can debug on both Tiger and Leopard.
As always, please report any problems.
Also, we've added updated compatibility notes on our website for
Leopard and various previous operating system
<http://www.ioxperts.com/leopard.html> -- please let me know if you
see anything incorrect.
(We're still cleaning up the pages, but figured is was better to have
something close to correct posted rather than waiting longer)
Happy New Year,
-Steve
----- changes in 1.1.2a42 -----
This is also primarily a regression test release as I've been
cleaning up the purchase and registration code in preparation for
doing a paid update.
(If you're currently testing a demo version and are about to purchase
a copy, please contact me off list as I could use some help verifying
the process once it's ready)
Also, I bumped the demo expiration date to 12/31 as the current betas
expire in in 3 days on 12/15. Please speak up if there are any
problems so they can be fixed before that happens.
Known issues:
1) Installing over 1.1.2a38 or later will give "no cameras" --
reboot and reinstall to work-around (2nd install will work).
----- changes in 1.1.2a41 -----
This is primarily a regression test and should be functionally
identical to 1.1.2a39 except that I've done a major cleanup of the
core logging code to allow better debugging of application
initialization and IPC.
I'd appreciate it if you could verify that no new bugs are introduced
relative to a39 while I add code that takes advantage to the new
functionaity.
----- changes in 1.1.2a39 -----
Fixed a crash in the logging version of the driver for the divio
chipset (passing a class instead of POD type to printf())
----- changes in 1.1.2a38 -----
Change ioxdeviced from StartupItem to launch-on-demand launchd daemon.
This fixes the problem with ioxdeviced quitting, resulting in no
cameras being visible -- it also has a bit more logging in case there
is still a problem.
My suspicion is that the daemon was being loaded to soon and either
getting in contention with one of the Apple drivers for the hardware
or running before something was ready.
Under Mac OS 10.4 and later, it is now registered with launchd and
loaded only when the video digitizer is accessed by QuickTime, which
will be much later.
It will also be relaunched automatically if it falls over.
One thing I did notice is that there may be an installer problem if
you install 1.1.2a38 over itself -- in this case no cameras will
appear in Camera Identifier. Please let me know if you see this
problem, but you can work around it by rebooting and installing again.
----- changes in 1.1.2a35,36,37 -----
bump expiration date.
----- changes in 1.1.2a34 -----
This is functionally equivalent to a33, except that I've updated to
the latest eSellerate SDK and added support for a few new Logitech
cameras.
----- changes in 1.1.2a34 -----
Update to latest eSellerate SDK
Support for new Logitech cameras
----- changes in 1.1.2a33 -----
Changes to Isochronous bandwidth allocation code and Isoc stream
startup code to prevent stream from restarting when stopping
----- changes in 1.1.2a29 -----
Fix to correct Gamma on newer Logitech cameras
Possible fix (and additional logging to detect) the Skype crash
Prefer YUY2 over MJPEG in UVC video mode selection
----- changes in 1.1.2a28 -----
1.1.2a28 extends the expiration date and includes a few minor
performance improvements.
I've also added some additional logging to try and isolate the
problem with the Philips SPC900NC not being detected after restart.
----- changes in 1.1.2a27 -----
Enabled Intel support for VLSI Vision CPiA-based Cameras
Use physically contiguous Isoch buffers on CPiA and Philips-based cameras.
Allow Isoch pipe reset when stopping stream -- should speed start/stop
----- changes in 1.1.2a26 -----
Added Intel support for cameras based on the Divio NW801 and NW802 chipsets.
Also fixed a few byte swapping errors in common code that may have
caused a few isolated problems.
----- changes in 1.1.2a21 -----
If you're having problems with crashes in Skype, this build _may_ help.
The primary change is that it holds off on some initialization of the
video pipeline until the as late as possible -- this may provide a
slight performance increase as well.
Hopefully there will be a matching Skype update to address the
threading issues we've been seeing.
The cause of the registration dialog popping up multiple times in
Skype is that Skype is opening and closing the digitizer multiple
times at startup -- this is not a problem, but somewhat annoying --
I'm looking at a fix to make the dialog appear only once per
application launch.
----- changes in 1.1.2a20 -----
1.1.2a20 adds support for Face Tracking on Intel-based machines.
In the process, we've done major work on the software pan/tilt/zoom
code which should result in improved performance, but should be
tested thoroughly for compatibility as there are significant
differences in the math.
----- changes in 1.1.2a18 -----
This is primarily to bump the expiration date as 1.1.2a17 expired
today, but we may have fixed a problem in the camera registration
code that could cause a camera to not be recognized under certain
circumstances.
For anyone who has one of the newer Logitech cameras and is having
problems with the audio, drop me a note off-list -- we have an audio
driver that works aroud the bug in the camera about ready for testing.
----- changes in 1.1.2a17 -----
This should fix the problems a few of you reported with the QuickCam
Pro 5000, Fusion, and (Black) QuickCam for Notebooks Pro.
The issue was that the firmware in those cameras returns incorrect
data for some of the controls related to the snapshot function, and
the driver caught and reported the error, unfortunately causing it to
fail on load with those cameras.
I've added code in the driver to work around the bug -- please
versify that the problem is fixed and that the fix didn't cause
issues with any other cameras.
There is still a known issue that the snapshot button on the new
Logitech cameras in not working -- I was hoping to get it fixed, but
didn't want to hold up getting something out with the previous
version expired.
---------
As always, please post any problems to the list.
