From bb67630b1cb81ba18f34add9eda0f81927ed9c85 Mon Sep 17 00:00:00 2001 From: Umang Jain Date: Tue, 30 Aug 2022 13:17:24 +0530 Subject: tests: stream: Add a colorspace adjustment test ColorSpace can be adjusted based on the stream's pixelFormat being requested. Add a test to check the adjustment logic defined in ColorSpace::adjust().
