At most one raw stream and one\nprocessed stream (possibly both at once) are supported.\n\nAn example ‘cam’ invocation requesting a raw stream rather than a debayered stream:\n\n cam -c1 -C8 -s role=raw,width=1920,height=1080 -Ffile#.raw\n\nOr for both raw and processed streams:\n\n cam -c1 -C8 -Ffile# \\\n -s role=viewfinder,width=1920,height=1080,pixelformat=RGB888 \\\n -s role=raw,width=3280,height=2464,pixelformat=SRGGB8 \\\n\nWhen only a raw stream is requested, there are no exposure/gain\nadjustments applied. This could be improved in future, once software\nISP gets a mechanism to gather image statistics without processing and\nusing them to make the adjustments, or once manual exposure controls are\nadded to software ISP. In the meantime, exposure must be changed\nexternally.\n\nChanges in v3:\n- Significantly reworked, with both functional and clarity improvements.\n The level of guesswork and confusion is hopefully reduced enough now\n to drop the RFC prefix.\n- The number of streams is set to 2 only with software ISP.\n- SimpleCameraData::pipeConfig_ nullptr check patch dropped.\n- PPM/raw file output patch dropped from this series. Let’s handle this\n separately as the patch series is already complex enough.\n\nChanges in v2:\n- Completely reworked.\n- Extended to be able to produce a raw stream together with a processed\n stream.\n\nMilan Zamazal (8):\n libcamera: simple: Set the number of software ISP streams to 2\n libcamera: simple: Don't use raw output formats with conversions\n libcamera: simple: Add plain output configurations\n libcamera: simple: Identify requested stream roles\n libcamera: simple: Consider raw output configurations\n libcamera: simple: Validate raw stream configurations\n libcamera: simple: Don't enforce conversion with an added raw stream\n libcamera: simple: Make raw streams working\n\n src/libcamera/pipeline/simple/simple.cpp | 231 +++++++++++++++++------\n 1 file changed, 173 insertions(+), 58 deletions(-)"}
