They serve as output buffers, even when a processed stream is produced. At most one raw stream and at most one processed stream are supported and can be combined. An example of producing both raw and processed files using `cam' application: cam -c1 -C100 -Ffile# \ -s role=viewfinder,width=1920,height=1080,pixelformat=RGB888 \ -s role=raw,width=3280,height=2464,pixelformat=SRGGB8 \ Note the difference in viewfinder and raw stream sizes due to the fact that debayering requires enlarging the image width, which enforces selecting a larger sensor resolution in this case. In order to distinguish between different cases, processedRequested_ and rawRequested_ flags are copied from SimpleCameraConfiguration to SimpleCameraData after successful configure(), similarly to useConversion_ flag. This is the final step to make raw streams working.
