Special devices

Some specific devices make use of Hardware-Accelerated Streaming by default. These are special cases, in that an active Plex Pass subscription is not required for the functionality.

  • NVIDIA SHIELD
  • WD My Cloud Pro PR2100
  • WD My Cloud Pro PR4100

Tip! : On these specific devices, a Plex Pass subscription is not required . Hardware-Accelerated Streaming is turned on by default for everyone on these devices.

On top of that… here’s the WD PR4100’s transcoding capabilities from Plex’ NAS compatibility list:

  • CPU: x64 (Pentium N3710)
  • Software Transcoding
    • SD 480p / 576p: yes
    • HD 720p: yes
    • HD 1080p: some (may or may not be able to transcode videos of this type; success dependent on material used)
    • 4K SDR 2160p: no
    • 4K HDR 2160p: no
  • Hardware-Accelerated Transcoding
    • SD 480p / 576p: yes
    • HD 720p: yes
    • HD 1080p: yes
    • H.264 2160p: no
    • HEVC SDR 2160p: no
    • HEVC UHD 2160p: no

So where is the option to set “Use hardware acceleration when available”

Live TV and DVR via HDHomerun is freezing and buffering when Transcoding is required for remote usage.

As per the linked support article… the PR4100 automatically makes use of the hardware accelerated transcoder… hence no option/flag in the settings.
If your playback is freezing/buffering you might need to share some more details as for what media you’re trying to play (e.g. some characteristics like codecs for video/audio/subtitles, resolution, bitrate…).

Not sure what else you need.

Well according to that photo.
It is transcoding video from 1080i mpeg2 to SD H264 and the audio from AC3 5.1 to AAC
which looks about right but the remote is only 712 Kbps, surprised it plays at all.
