2021-01-22android: camera_device: Copy camera3 buffers in descriptorJacopo Mondi
The camera3_stream_buffer_t instances part of a capture request contain information on the stream for which capture has been requested (size, format and fences) and a handle to the stream's memory buffers. This information is copied in the descriptor one piece at the time while processing the camera3 streams to be re-used at request completion time. Simplify the code by copying the stream information in the descriptor at construction time.

The Camera3RequestDescriptor class can access the number of buffers and the frame number from the camera3_capture_request_t instead of having the caller passing them to the constructor. This change allows to access other fields of the capture request, such as the capture settings.

Add support for setting V4L2_CID_VBLANK appropriately when setting V4L2_CID_EXPOSURE. This will allow adaptive framerates during viewfinder use cases (e.g. when the exposure time goes above 33ms, we can reduce the framerate to lower than 30fps). The minimum and maximum frame durations are provided via libcamera controls, and will prioritise exposure time limits over any AGC request.

2021-01-04android: camera_device: Only advertise RAW support if RAW16 is availableNiklas Söderlund
The Android camera2 API defines a RAW capture capability ([1]) for devices that support "outputting RAW buffers and metadata for interpreting them". This capability requires the camera device to support RAW_SENSOR ([2]) as an output format. Despite what its name may sound like, the RAW_SENSOR format is defined as a 16 bits RAW format, not an opaque implementation-dependent format (which is instead called RAW_PRIVATE). Devices may additionally support the RAW10 and RAW12 formats, but that isn't enough to claim RAW capture capability. To comply with the API requirements, only report the ANDROID_REQUEST_AVAILABLE_CAPABILITIES_RAW capability when 16-bit RAW is supported.
