When a raw stream is requested, whether alone or together with a processed stream, its buffers must be handled outside the software ISP machinery. They serve as output buffers, even when a processed stream is produced. But when both processed and raw streams are requested, the buffer can be completed only after the processing is finished, to make sure it's untouched by the application as long as the processing runs. 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 track whether a raw stream is requested and which one it is, SimpleCameraData::rawStream_ member variable is introduced. This is the final step to make raw streams working.
