Creative Live! Cam Vista IM test

[Thomas Hickethier]

Dear developers,

I'd like to support you (and me) in testing the macam driver with the
Live! Cam Vista IM camera by Creative Labs.

I tried it but it doesn't work properly. Some time ago I was already in
contact with Harald (hxr) in March of this year, but we did not get
progress. Now I tried just the new CVS build (2007-10-17)  but still
without success.

In the 0.9.1 release note the webcam is listed with the remark:
• Added support for Creative Live! Cam Vista IM (needs testing)
So I would like to do that because I'm interested in getting this
camera working with your drivers.

My system is an iMac G5 1.8Ghz, 1GB with WLAN and Bluetooth inside. OS
X is version 10.3.9 including all updates (except iPodUpdater, iSight,
Remote Desktop Client).

When I start Macam the application I get status indication about
connected webcam:
Status: Verbunden mit Creative Live! Cam Vista IM
But the screen is black. If I press the play button, for a moment the
staus line changes into Wiedergabe and the Video record button becomes
highlighted. But screen remains black and status line changes into:
Status: USB-Kommunikationsfehler.
The greed LED at the webcam gets on when starting the application and
remains on when stopping the application.

The console displays this, when I start the application:
## Component Manager: attempting to find symbols in a component alias
of type (regR/carP/x!bt)
USB Library Version = 2.0.5
USB Family Version = 2.1.5
USB Interface ID = 215
I2C synced in 1 attempt
Found OV7xx0 sensor.

When I press the play button, it displays this:
alt interface 0:
   pipe 0: ANY 0 CONTROL 8 0
   pipe 1: IN  1 ISOC 0 1
alt interface 1:
   pipe 0: ANY 0 CONTROL 8 0
   pipe 1: IN  1 ISOC 384 1
alt interface 2:
   pipe 0: ANY 0 CONTROL 8 0
   pipe 1: IN  1 ISOC 512 1
alt interface 3:
   pipe 0: ANY 0 CONTROL 8 0
   pipe 1: IN  1 ISOC 768 1
alt interface 4:
   pipe 0: ANY 0 CONTROL 8 0
   pipe 1: IN  1 ISOC 896 1
Setting alt to 4, (with packet-size = 896), return is 0
Checking pipe status, return is 0
Checking pipe properties, return is 0
   pipe 1: IN  1 ISOC 896 1
usbGetIsocFrameSize returning 896
JPEG compression is being used, decompression using method 1
2007-10-25 23:30:01.054 macam[454] GenericDriver: grab aborted because
of invalid data stream (too long without a frame, 1050 invalid frames,
0 invalid chunks)

The macam.component I also checked with Skype (v2.5.0.85). It also
detects the camera correctly (seen at the preferences, Video) by
displaying the correct camera name, but the preview window remains
white.

Can I do anything else to get progress here?
The camera works with a windows PC, so its not a HW defect.

Thanks for your reply in advance,
Best regards,

Thomas

Hi Thomas,

Thanks for your detailed report.

I am guessing that your camera has a sensor that is
very slightly different from the one in the code.
Other OV519 cameras do work, so yours is very close!

It should be possible to figure out which sensor you have,
and to initialize it properly (I am guessing that this is where
the problem is). I will soon make a "debug" build available
that will generate even more information!

You should be able to compile on your machine if you wish,
although there is probably some complication.

I'll let you know when a debug build is available.
Thanks,
Harald
