[libvidcap-devel] MacOSX: Getting rid of those deprecated warnings

[Roman H. <rom...@po...>]

Hi,

a few Months ago I was developing my own  platform independed webcam  
library, before I found this library.
At least the Mac version was very similiar to your version  because  
both take the sequenceGrabber and extract the video
  picture by picture form the GWorld with the deprecated functions  
GetGWorldPixMap and Un-/LockPixels.

This is the way the QuickTime Sample Hack TV Carbon Example (http://developer.apple.com/samplecode/HackTVCarbon/index.html 
) or
BrideOfMungGrab Example (http://developer.apple.com/samplecode/BrideOfMungGrab/index.html 
)
has done it as well.

Now  as I understood the GWorld concept has been replaced by the new  
CoreImage system, but I don't find any functions to simply get the  
same functionality with CoreImage than the GetGWorldPixMap and Un-/ 
LockPixels functions.

Now my question:

Is there somebody working on this? Or should I investigate further?

I am not happy with the performance of the current version, since it  
takes more cpu load than the Windows Version. Perhaps the Locking and  
Unlocking of the GWorld is too expensive and there is a better way.
