    Here are a few simple ways that can help solve the problem with the Calista remotefx codec. Alternatives to Hyper-V RemoteFX can Microsoft recommends that consumers use DDA instead of RemoteFX after April 2021. DDA (Discrete Device Assignment) is a feature that makes it easy to connect a smartphone (in my case, a PCI Express device) directly to a virtual machine.

    remotefx calista codec

    Microsoft RemoteFX is a trademark of Microsoft and covers a range of browsing enhancement technologies related to the Desktop Remote Protocol (RDP) remote display protocol developed by Microsoft.[1] RemoteFX should have been first introduced in Windows Server 2010 R2 SP1 and is based on intellectual property acquired by Microsoft and has been enhanced since the acquisition of Calista Technologies.[2] It is part of all Remote Desktop Workload Services.


    Windows Server R2 2008 SP1

    RemoteFX components introduced in Windows Server R2 2008 SP1 include:

  • RemoteFX vGPU: The ability to showcase a virtualized instance of the physical GPU in various Windows 7 virtual machines. Allows your virtual machines to access the traditional GPU and enables hardware acceleration for graphics-heavy e-book scenarios such as 3D rendering . to games.
  • RemoteFX USB Redirection: Often used to support redirecting USB devices to a virtualWindows 7 virtual machines. These devices, connected to thin patient terminals, are used in electronic machines.[3] [4]
  • RemoteFX Codec (also known as RemoteFX Calista Codec): An all-new lossy codec that provides reliable, high-fidelity video and text playback. The RemoteFX codec requires absolutely no special hardware and uses the CPU for encoding. Server [5]

  • In Windows Server 2012, implementation components have been added to RemoteFX.[6]

  • RemoteFX Responsive Graphics: The RemoteFX graphics direction dynamically adapts to different conditions, runtimes such as graphics content types, processor, available network bandwidth, and client speed. [7]
  • RemoteFX for WAN. The a-series introduces network bearer changes to support UDP and provide unified survivability across WAN and wireless network settings.[8]
  • RemoteFX Multi-Touch: Improved remote gesture control (such as pinch and zoom) between client and host, and up to 256 touch pointssled[9]
  • RemoteFX Multimedia Redirection API: Provides native integration of IP Voice into Applications (VoIP) with RemoteFX in mind and enables the transmission and playback of audio and video content directly on the client side.[10]< /up>
  • GPU selection. All RemoteFX features can be used with the software-emulated GPU available by default in all virtual machines and session companies, or they can be electronically accelerated by hosting the graphics card and then enabling RemoteFX. vGPU.[11]
  • RemoteFX vGPU: new support for DirectX 11[9]
  • RemoteFX USB Redirection: Updated to support all remote communication scenarios on desktops, vGPU-enabled VMs, traditional VMs, desktops, and physical session desktop hosts[9].
  • RemoteFX Codec (also known as RemoteFX Progressive Calista Codec): Updated to enable progressive rendering, which is more efficient when rendering content on any of our WANs by sending images from high resolution only when bandwidth allows.[12]< /sup >
  • Windows 2016, Windows 10 Enterprise Server

    In Windows Server 2016 (RDP 10), each of the following has been added to RemoteFX.[13]

  • Enable the OpenGL 4.4 and OpenCL 1.1 APIs in the virtual machine using the RemoteFX adapter
  • More video memory for the RemoteFX adapter
  • Various performance improvements in vehicle implementations and APIs.
  • RemoteFX Media Streaming (H.264) replaces Media Redirection (MMR). Note. MMR is now completely removed from RDP 10 as RemoteFX Media Streaming works for all types of video content, while MMR only works for some.[14]

    Discontinuation Of RemoteFX VGPU Support

    Is RemoteFX deprecated?

    In early July 2020, the RemoteFX virtual GPU was deprecated due to security vulnerabilities in all versions of Windows.It is expected to be phased out completely in February 2021.

    As of July 2020, the RemoteFX virtual GPU has been deprecated in all versions of Windows due to security vulnerabilities. It should be completely removed in February 2021. Windows [15]

    In Server 2008 R2, the entire RemoteFX codec could be used to host both sessions (Remote Desktop Session Hosts) andVDI scenarios (and remote desktop virtualization hosts). The benefits of RemoteFX vGPU and RemoteFX USB Redirection can only be used in VDI (Remote Desktop Virtualization Hosts) scenarios.[16]

    How do I enable RemoteFX 3D video adapter?

    Open Hyper-V Manager, navigate to the virtual machine settings and select “Add Hardware”. Select RemoteFX 3D Graphics Adapter, and then select Add. As a general rule, set the maximum number of monitors, maximum LCD resolution, and dedicated video memory and leave the default values.

    Windows 10 version 1511 introduced the RemoteFX – Hyper-V client, which removes the dependency on the Remote Desktop Services role.[17]

    How do I enable RemoteFX in Windows 10?

    Click Start, click Run, type gpedit. msc, then click OK. Navigate to: Computer ConfigurationAdministrative TemplatesWindows ComponentsRemote Desktop ServicesRemote Desktop Session HostRemote Session Environment. Now double-click Configure RemoteFX, click Enabled, and then click OK.

    Gen 2 virtual machines on Windows Server 2012 R2 do not support RemoteFX.[18] Windows Server 2016 added this support.[19]

    In Windows Server 2012, all RemoteFX features (except the associated virtual GPU) can be used with or without the dominant physical GPU on the server.[20] If the server does not have a GPU a web server processor emulated by synthetic content rendering software. If an absolute GPU is present in the Internet Calculator, it can accelerate any vGPU function to share graphics via RemoteFX.

    RemoteFX VGPU Requirements

  • Hyper-V is installed on the server. VMs must be running and created in Hyper-V.
  • The server processor must support Enable second level address (SLAT) and translation and must be enabled.
  • For Windows Server 2008 R2 SP1 or later, the server can have at least one DirectX 9.0c and 10.0 compatible graphics card installed.
  • For Windows Server 2012, the server must have at least a DirectX 11.0 compatible graphics card with a WDDM 1.2 card and driver.[22]
  • The computer host does not have to be a domain controller. For a single server installation, Microsoft supports transferring a domain as a controller to a Hyper-V web machine.[23]
  • Windows Server 2008 R2 SP1 has been tested on a maximum of 14 virtual machines per GPU, for a total of twenty-four virtual web servers on two physical GPUs.
