Extension SDK Developer Guide

DCV enables high-performance remote access to WorkSpaces instances for a wide range of workloads and use cases. With the Amazon DCV Extension SDK, developers can customize DCV WorkSpaces experience for end users, including:
+ Facilitating custom hardware support.
+ Enhancing the usability of third-party applications in remote sessions. For example, adding local audio termination for VoIP applications or local video playback for conferencing applications
+ Providing accessibility software like screen readers with information about the remote session and applications running remotely.
+ Allowing security software to analyze the security posture of the local endpoint to allow conditional access policies.
+ Performing arbitrary data transfers over an established remote session.
