For some unknown reason I can't play HEVC encoded video with MP1 on my system. I have tried every trick I know, but nothing works. Video stutters and jumps, audio lags. However these same files WILL play with other media players such as VLC, MPV for Windows, stand alone Windows Media Player, and the MS Movies and TV app. So why, if HEVC plays on Windows Media Player in stand-alone mode, does it not play using MediaPortal?
I have ruled out skins, since changing them does not matter. I prefer StreamedMP.
I have ruled out my wifi connection to my media server (an SSD hardwired to my router), buy attempting to play HEVC directly from the OS Desktop. No change.
I even tried different monitors and nothing changed.
I changed the power settings for performance in the UEFI firmware and OS (probably redundant) and nothing changed.
Here are some of my media computer specs:
