At most one raw stream and one processed stream (possibly both at once) are supported. An example ‘cam’ invocation requesting a raw stream rather than a debayered stream: cam -c1 -C8 -s role=raw,width=1920,height=1080 -Ffile#.raw Or for both raw and processed streams: cam -c1 -C8 -Ffile# \ -s role=viewfinder,width=1920,height=1080,pixelformat=RGB888 \ -s role=raw,width=3280,height=2464,pixelformat=SRGGB8 \ When only a raw stream is requested, there are no exposure/gain adjustments applied. This could be improved in future, once software ISP gets a mechanism to gather image statistics without processing and using them to make the adjustments, or once manual exposure controls are added to software ISP. In the meantime, exposure must be changed externally. Changes in v4: - Broken range pruning due to passing a value rather than a reference fixed. - New common function isFormatRaw introduced. - The patch assigning colour spaces in the simple pipeline, previously posted separately, included in this series, as the first patch. It can still be handled separately; in any case the rest sort of depends on it. - Setting metadataRequired to false where needed to prevent freezes and assertion errors; related to metadata reporting support merged to master since v3. Changes in v3: - Significantly reworked, with both functional and clarity improvements. The level of guesswork and confusion is hopefully reduced enough now to drop the RFC prefix. - The number of streams is set to 2 only with software ISP. - SimpleCameraData::pipeConfig_ nullptr check patch dropped. - PPM/raw file output patch dropped from this series. Let’s handle this separately as the patch series is already complex enough. Changes in v2: - Completely reworked. - Extended to be able to produce a raw stream together with a processed stream.
