Hi Frank, 

I'm not sure what the problem might be. 
Your camera uses the MySPCA500Driver[.h.m]
The USB communication is probably fine, since it says 
"Playing"; if there were some prblems then this would change. 

If you can, try your camera with a PPC Mac, remember you 
only need to run the macam application, which does not need to 
be installed, so you can run  it from a disk image or a flash drive. 
If this works, then it is a byte order issue. Actually, you can probably 
just set the macam application to run in Rosetta mode or something 
(I don't have an Intel Mac, so I don't know exactly). That is 
probably much easier.

In any case, I would put some kind of printf statement between 
lines 709 and 710 to examine the contents of the currBuffer; to 
make sure that is has enough data (> 10K), and maybe to see 
what it looks like. Then you need to figure out whether your 
images are compressed or not. You may want to try different 
settings of the compression slider. 

If it is a byte-order issue, then it is probably something with 
one of the decoding routines, sometimes there is code that 
assumes certain byte-orders. Beware of pointers to things
that are bigger than bytes. 

Let me know what you find out, and I'll help out too.
Thanks,

Hello Macam developers,

I found the Macam project when looking for an OS X driver for my  
Kodak EZ-200 webcam. I'm familiar with coding using Xcode and  
software development in general so if some technical stuff is  
required to troubleshoot this I'm not hesitant to jump in.

I'm using Tiger 10.4.6 on a 1.83 Ghz Macbook Core Duo. It's pretty  
much a stock machine without any software updates applied because  
Quicktime 7.1.3 breaks the current Flip4Mac WMV components. I can  
retest on 10.4.8 with updates if necessary since I've got some free  
space on my HD to fiddle around.

I downloaded Macam 0.0.9 and started the "Macam" application. I get  
the brushed metal interface with a black rectangle and "Status: No  
Camera".

Now, I connect the Kodak EZ-200 to one of my Macbook's USB ports, the  
Macam application window gets updated: the "Play" button gets  
activated and the status bar now reads "Status: Connected to Kodak  
EZ200 (experimental)". The black rectangle inside the window also  
resizes from 320x240 to 640x480. So far so good it seems.

Since I'm not familiar with Macam or how it should work, I pressed  
the Play button. Three things happen then: the Play icon becomes a  
Pause icon, the status bar now reads "Status: Playing" and the black  
rectangle turns a solid shade of grey. Also, the toolbar icons change  
their state a bit ("image snapshot" is now enabled).

Nothing much happens at this moment. I can create image snapshots by  
clicking the button, but they're all grey. Adjusting the sliders in  
the camera video settings drawer doesn't do a thing - I can not  
change the shade of grey, it remains hex color #808080.

Since nothing seems to work, I press the Pause button. The rectangle  
turns black again. I tried changing the "Format" of the camera  
settings, but none seem to work - the rectangle size changes but I  
only get a black or grey rectangle. Quitting the application works  
properly when the application is in Pause mode.

I'd gladly help debugging this problem and getting the camera to  
work, but I would need some tips to start my journey. Thanks in  
advance for your time and replies, keep up the good work!

With kind regards, from the Netherlands,

Frank Schoep
