`mediaStream.enableHardwareAcceleration(true)` always resolves to `false` which I think means is its failed to enable hardware acceleration. Is the API not supported yet? **Which Web Video SDK version?** 1.2.0 **Device :** - Device: Macbook Pro - OS: macOS 11.6.1 - Browser: Chrome, Firefox ---

Hey @shoaib Thanks for your feedback. The `hardware acceleration` is a prerequisite for enabling 720P, Video SDK Web can only support Intel or Nvidia graphic cards on Windows platform. So the `mediaStream.enableHardwareAcceleration` always return `false` on macOS. We are working on the solution for other platforms. Please stay tuned. Thanks Vic ---
