rocJPEG chroma subsampling and hardware capabilities
********************************************************************

rocJPEG supports the following chroma subsamplings:

* YUV 4:4:4
* YUV 4:4:0
* YUV 4:2:2
* YUV 4:2:0
* YUV 4:0:0

The following table shows the capabilities of the VCN and total number of JPEG cores for each supported GPU
architecture:
