2020-10-02src: android: exif: Set the class byte orderingKieran Bingham
The exif object sets the byte ordering on construction, and then during later calls re-states the byte ordering when setting values. It could be argued that this ordering should already be known to the exif library and is redundant, but even so we must provide it. Ensure we are consistent in always using the same byte ordering by setting a private class member to re-use a single value.

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.

When producing the list of image resolutions to claim as supported by the camera HAL, the JPEG stream was assumed to be 'always valid' as, at the time, there was no JPEG support in place at all. With the introduction of support for JPEG compression, reporting non-valid sizes as supported obviously causes troubles.

2020-09-16android: Protect against null callbacksLaurent Pinchart
According to the Android camera HAL C interface documentation, the camera service is supposed to set callbacks after initializing the HAL and calling get_number_of_cameras(), before any other calls to the module. We rely on this behaviour and use callbacks unconditionally, which would lead to a crash if the camera service behaved incorrectly. 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.
