Expose the self stream to applications and prefers it for the viewfinder
and video roles as it can be extended to produce RGB. Keep preferring
the main path for still capture as it could be extended to support RAW
formats which makes most sense for still capture.
With this change the self path becomes available to applications and a
camera backed by this pipeline can produce two streams simultaneously.

Extend the format validation to work with both main and self paths. The
heuristics honors that the first stream in the configuration has the
highest priority while still examining both streams for a best match.
It is not possible to capture from the self path as the self stream is
not yet exposed to applications.

The buffer ready handlers are designed for a single application facing
stream from the main path. To prepare for multiple application facing
streams from main and/or self path the handlers need to be prepared.
The data keeping track of the frame number and advancing the timeline
can be moved from the application facing buffer ready handler to the
statistics handler. For each request processed there will always be a
statistic buffer and as the ISP is inline and is the source of both
main, self and statistic paths there is no change in behavior.
The application facing handler no longer needs a special case for
cancelled frames and can be made simpler. With this change the handlers
are ready to deal with any combinations of application facing streams.

follow the buffer ordering (be it internal or external) given by
incoming Requests.
This is essential, otherwise we risk dropping frames that are meant to

When calculating the pipeline configuration for the IPU3 platform,
libcamera tries to be smart and select the smallest sensor frame
resolution large enough to accommodate the stream sizes
requested by the application.
While this makes a lot of sense, in practice optimizing the
selected sensor resolution makes the pipeline configuration calculation
process fail in multiple occasions, or results in stalls during capture.
As a trivial example, capturing with cam with the following command
line results in a stall:
$ cam -swidth=1280,height=720 -swidth=640,height=480 -c1 -C
Likewise, the Android HAL supported format enumeration fails in
reporting smaller resolutions as supported when used with the OV5670
sensor.
320x240:
DEBUG IPU3 ipu3.cpp:192 CIO2 configuration: 648x486-SGRBG10_IPU3
ERROR IPU3 imgu.cpp:408 Failed to calculate pipe configuration
ERROR IPU3 ipu3.cpp:299 Failed to calculate pipe configuration: unsupported resolutions.
640x480:
DEBUG IPU3 ipu3.cpp:192 CIO2 configuration: 320x240-SGRBG10_IPU3
ERROR IPU3 imgu.cpp:408 Failed to calculate pipe configuration
ERROR IPU3 ipu3.cpp:299 Failed to calculate pipe configuration: unsupported resolutions.
Furthermore the reference xml files used for the IPU3 camera
configuration on the ChromeOS platform restricts the number of sensor
resolution to be used for the OV5670 sensor to 2 from the 6 supported by
the driver [1].
The selection criteria of the correct CIO2 mode are not specified, and
for the time being, as a workaround, always use the sensor maximum
resolution at the expense of frame rate and bus bandwidth to allow the
pipeline to successfully support smaller modes for the OV5670 sensor and
solve pipeline stalls when capturing with both sensors.
[1] See the <sensor_modes> enumeration in:

The stream assignment was based on the order in which elements were

need to keep that association in place, and the streams_ vector is now
