Hardware Transcoding issues - ApolloLake & GeminiLake CPUs

Hey Folks,

Quick update on Apollo Lake CPUs.

I’ve been working with @ChuckPa. I loaded an alpha (pre-QA) version of PMS 1.32.5 on my DS918+, which has the Celeron J3455 CPU.

Here’s some initial results:

Jellyfish 80 Mbps H.264 HD & 120 Mbps HEVC UHD: Hardware transcoding engaged. Playback was smooth, with no buffering.

LG New York UHD HDR: Hardware transcoding & tonemapping engaged. Colors looked good. Playback was smooth with no buffering.

LG Colors of Journey UHD HDR: Hardware transcoding & tonemapping engaged. Colors looked good. Playback did buffer a few times. However, this video is 60 FPS, so it is pushing the limits of the J3455.

Clients were Android mobile on a Pixel 6a, configured to transcode to 1080p, 8 Mbps, and Plex for Windows, forcing a transcode to 1080p, 10 Mbps.

I loaded the alpha on my system a couple of hours ago and ran the tests. Chuck asked that I drop an update to the thread. Wanted to let you know things are progressing.
