[Spca50x-devs] (no subject)

Hi all, 
I have implemented a lot of new features for the rawjpeg cameras: spca500a  
spca504a spca504b and spca533a. 
All these cameras have now a hardware and a software resolutions 
 
The software resolution asked by the userspace are obtain by the first  
available hardware resolution and a crop function.Only the surface need by  
the user space is decoded (crop is in the IDCT loop). 
The available resolutions are: pal 384x288, sif 352x288, cif 320x240, qpal  
192x144 and qsif 176x144. vga 640x480 is available for the cam able todo  
that. 
A tasklet is schedule in the interrupt handler to perform the decoding in  
"safe times" this feature allow to play with rgb16 rgb24 rgb32 and yuv in  
full size full frame rate without garbage (you need a good computer i686). 
If the isoc stream is corrupted a feature drop the corrupted frame and  
recycled the buffer for a new one. 
The code source is available at http://mxhaard.free.fr for testing 
please feedback are wellcome:) 
Enjoy!!
