raspberrypi/libcamera / src/android/camera_device.cpp / sortCamera3StreamConfigs / L66-L165

Reorder the configurations so that libcamera::Camera can accept them as much as possible. The sort rule is as follows. 1.) The configuration for NV12 request whose resolution is the largest. 2.) The configuration for JPEG request. 3.) Others. Larger resolutions and different formats are put earlier.

raspberrypi/libcamera / src/android/meson.build / 2ca75f012f

android: Disable build on platforms without mbrtoc16() The Android camera HAL uses mbrtoc16(), which is not provided by uClibc. We could work around the issue by adding an implementation of the function to libcamera::utils (probably based on mbrtowc()). Usage of the Android camera HAL with uClibc however is such a nic…
