HW Transcoding Intel: decode but no encode

Plex Media Server Desktops & Laptops

Can someone help me figure this one out? I have a barely supported quick sync I7 2600. Per Intel it supports H.264 Decode and Encode (which is 99% of my library). The problem is I can only get (hw) decoding and never encoding. GPU utilization is only about 10% per stream.

TL;DR:

Debug — TPU: hardware transcoding: using hardware decode accelerator dxva2
Debug — [Universal] Using local file path instead of URL: Harry Potter and the ...
Debug — TPU: hardware transcoding: zero-copy support not present
Debug — TPU: hardware transcoding: final decoder: dxva2, final encoder:

I’ve attached log.txt (18.6 KB) a log when I started the transcode until plex starts shipping the data.

*I did have a Geforce GT 610 which didn’t support NVENC that i’ve since disabled/uninstalled/removed/and restarted before this log

Server Version#: Windows 1.13.8.5395
Player Version#: Android (new), Web Client, Fire TV etc

another Example with H.264 -> H.264 (MKV container) that should work.log2.txt (19.4 KB)

STREAM   -   Transcode (Speed: 4.6)
CONTAINER   -   Transcode (MKV  MPEGTS)
VIDEO   -   Transcode (H264 (HW) 1080p  H264 720p)
AUDIO   -   Transcode (AC3 5.1  AC3 5.1)
