This release expires Dec 15, 2007

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.

Thanks,

-Steve

----------------

As well as the fixes in a38, I think I've fixed a crash in the 
logging version of the driver for the divio chipset.

This has the same problem as a38 where you may see "no cameras" after 
installing over a previous version.

If this happens, restart and reinstall -- the 2nd install should be successful.

Sorry for the delay,

-Steve

----------------

I think I may have a fix for 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.

If you have been having this problem, I'd appreciate it if you can 
disable any workarounds you've been using and try this release to see 
if it fixes the problem.

My suspicion is that the daemon was being loaded to soonand either 
getting in contention with one of the Apple drivers for the hardware 
or 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.

I'd also appreciate it if someone running 10.3.9 or older could 
verify that the fix does not cause problems on older OS versions 
where launchd is not available.

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.

Thanks,

-Steve

----- changes in 1.1.2a38 -----

Change ioxdeviced from StartupItem to launch-on-demand launchd daemon.

----- 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.
