This allows the pipeline to return any stream buffer requested by the application as zero-copy. Advertise the Unicam Image stream as the RAW capture stream now.

2020-09-18libcamera: ipu3: Always use sensor full frame sizeJacopo Mondi
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.

2020-09-18android: camera_device: Rework CameraStream handlingJacopo Mondi
The CameraDevice::streams_ vector of CameraStream instances is currently mostly accessed by index. The current implementation creates all the CameraStream during the first loop that inspects the camera3_stream instances and then update the index of the StreamConfiguration associated with the CameraStream during a second loop that inspects MJPEG streams. A third loop creates the JPEG encoder associated with camera streams that produce MJPEG format. As the index-based association is hard to follow and rather fragile, rework the creation and handling of CameraStream: 1) Make the StreamConfiguration index a constructor parameter and a private struct member. This disallows the creation of CameraStream without a StreamConfiguration index assigned. 2) Create CameraStream only after the associated StreamConfiguration has been identified. The first loop creates CameraStream for non-JPEG streams, the second for the JPEG ones after having identified the associated StreamConfiguration. Since we have just created the CameraStream, create the JPEG encoder at the same time instead of deferring it. This change removes all accesses by index to the CameraDevice::streams_ vector. No functional changes intended, but this change aims to make the code easier to follow and more robust.

While the camera service isn't supposed to behave incorrectly, gracefully handling the error when opening cameras isn't costly, and provides better diagnostic than a crash.

2020-08-27pipeline: raspberrypi: Set sensor default orientation before configure()Naushir Patuck
The default sensor orientation must be set early on in match() to ensure generateConfiguration() and configure() return out the correct Bayer ordering to the application. This is particularly important for RAW capture streams.

The sensor aligns the width and height to multiples of two pixels, and the scaler has a x3 hardcoded factor. The output size must thus be aligned to 6 pixels, not 3. Fix it.
