Introduction

This document provides an overview of the High Level testing requirements for the Device Settings Video Device module. It outlines the scope of testing, objectives, testing levels and approaches, specific test requirements, and expected deliverables.

Interface of the test is available here: dsVideoDevice HAL header

Module Description

DS Video device HAL provides a set of APIs to initialize, query and set information about about the zoom mode, HDR capabilities, Video encoding formats and frame rate.

Interface specification is available here: dsVideoPort HAL Spec

Testing Scope

#	Test Functionality	Description
1	Check the Zoom Control	Verify setting and getting the zoom modes
2	Check the HDR Capability	Check the HDR Capability
3	Check Video codec and Formats	Check supported video codec formats
4	Check the Display frame rate Capability	Check supported Display frame rates

Emulator Requirements

Boot configuration: Check video ports, encoding formats, profiles, frame rates, and device-supported zoom modes, along with the number of ports supported by each device.

Check the Zoom Control

Test Functionality	Description	HAL APIs	L2	L3	Source	Sink	Control plane requirements
Check the zoom mode status	Loop through each supported video device and the zoom mode can be set using Source_VideoDevice.yaml(dsVideoDevice/Device/[Device Number]/SupportedDFCs) profile file and verify using get function.Note:Supported Number of VideoDevices check this profile file for source Source_VideoDevice.yaml(dsVideoDevice/NumVideoDevices)	dsGetVideoDevice(), dsSetDFC(), dsGetDFC()	Y	N	Y	NA	NA
	Loop through each supported video device and the zoom mode can be set using Source_VideoDevice.yaml(dsVideoDevice/Device/[Device Number]/SupportedDFCs) profile file and verify using get with Video playback & connected device. Note:Supported Number of VideoDevices check this profile file for source Source_VideoDevice.yaml(dsVideoDevice/NumVideoDevices)	dsGetVideoDevice(), dsSetDFC(), dsGetDFC()	NA	Y	Y	NA	Y
