I have Plex Media Server and Plex Home Theater running on the same computer. It's a small HTPC with 4GB of RAM and an i3 CPU. I'm running Lubuntu 15.04.
I was trying to play a 1080p video, with the HEVC codec. I guess it has a pretty high bitrate (7 772 Kbps). It's only a 30 min video, and it's 1.65 GiB.
So when I play the video in Plex Home Theater, I see a whole bunch of transcoding processes. Unfortunately, the CPU can't keep up, and the video keeps stalling.
I tried installing libde265, but that didn't fix it. Is there anyway I can get Plex Home Theater to play HEVC without transcoding? I think it should be fast enough to play without transcoding.
For now I'm just converting the video to h264 using ffmpeg. But I might need to play more HEVC videos in the future, so it would be good to figure this out.
