Avichal Rakesh	e6a88a8119	ExternalCameraHAL: Check for empty native handle instead of null. ... AIDL cannot send nullptr when parceling NativeHandles. Instead, it sends an empty handle. Logic which previously relied on null checks should now rely on checking if the native_handle is empty or not. This CL updates ExternalCameraUtils to check for empty handles instead. Bug: 299170474 Test: CameraAidlTest#processCaptureRequestInvalidBuffer passes Change-Id: Id4ba928defaa061708a3c1cd68aa510b376f6cb3	2023-11-02 17:27:43 -07:00
Avichal Rakesh	e1857f8dbd	Migrate reference external HAL implementation to AIDL ... Android T migrated the HAL interface to AIDL, but the reference HAL was never updated to use AIDL. This CL migrates the reference HAL implementation for external cameras to use AIDL as well. The external HAL uses V4L2 standard to expose USB cameras to the cameraserver. The reference HAL implementation for internal camera was dropped because it is not possible to write a generic HAL that works with some large percentage of internal cameras. Bug: 219974678 Test: Existing CTS tests pass with external camera connected. Change-Id: I35f3dc32c16670eca7735a4ac00fed3daf36aa65	2022-12-01 05:09:18 -08:00
