Abstract: A method of handling a hardware request in a computing device including one or more processors, comprises receiving a request for a hardware-related function from an application service module, determining if the hardware-related function can be provided by an OEM-specific SDK; based on a determination that the hardware-related function can be provided by an OEM-specific SDK, providing commands and parameters related to the hardware-related function to the OEM-specific SDK; based on a determination that the hardware-related function cannot be provided by an OEM-specific SDK, providing commands and parameters related to the hardware-related function to an operating system hardware abstraction layer.

Abstract: A system is provided that detects a start of a camera session, captures initial raw data frames and stores them in memory. Upon determining that the camera session corresponds to a video recording session, the system activates a video recording pipeline and upon determining that the video recording pipeline is active, the system retrieves the initial raw data frames, encodes the initial raw data frames using the video recording pipeline, accesses additional captured raw data frames, and encodes the additional captured raw data frames using the video recording pipeline until detection of an end of the camera session. Upon detecting an end of the camera session, the system deactivates the video recording pipeline.
