hardware encoding was recently introduced in spacedesk.
It seems that on your Windows machine, the Nvidia H264 Encoder MFT is missing – it is not listed underneath Video Encoders in the spacedeskDiag.txt that you’ve sent us.I suggest to update the driver version of your Nvidia graphics adapter. This may or may not install the components required for hardware encoding.
In case the Nvidia driver update did not help, switch to Software Encoding MJPEG (forced) in the spacedesk Android Viewer app. The option is available in the menu Settings -> Quality/Performance.

I enabled the Software Encoding MJPEG (forced) and it worked very well, thanks for the support.
