Server Version#: 1.29.2.6364 Player Version#: Latest on web and iOS My server is a Docker container on Synology 1520+ running DSM7.1.1. Transcoder not using hardware again when HDR Tone Mapping is on. This worked with 1.28.0 and briefly again with 1.29.1 (the early builds). It stopped with later …

If it matters, I get my image from the official source: plexinc/pms-docker.

I have the same issue, but on Windows. It worked until the last few days. Happened to look today and no HW decoding if tone mapping is on. It worked for many months (years?) perfectly (both HW decode and encode) on all my HDR content with tone mapping on. Tried upgrading to latest beta build 1.3…

I took advice from elsewhere on the forum and downgraded to 1.28.0.5999. HW decoding now works with tone mapping. Will have to leave until Plex fixes it. [image] Plex enable hdr tone mapping can not hw Plex Media Server Server Version#:1.28.1.6104 Hi, my plex server is…

Yeah, I know that’s an option, and I did go back to 1.28.0 for a bit. My point though is why put the fix into 1.29.1 and then take it out? As a software engineer, it feels like there was a merge issue somewhere, and the fix was dropped.

Changes to video drivers in 1.29.1 and not sure if it was accidental but transcoder upgrade in 1.30 which you find at the bottom of this thread: PMS 1.29.1 HW Tonemapping Testing, Questions , and Answers - #107 by tusing

I’m guessing that’s related. What’s interesting is that this was fix in the first builds of 1.29.1, and then broke again in follow-on builds of 1.29.1. Remained broken in 1.29.2. Somewhere in the builds of 1.29.1, the fix was dropped.

I upgraded to 1.30.0.6486. Same issue. HDR tone mapping using 100% CPU.

Same issue here. HDR tone mapping is not using hw acceleration on my machine runing Plex 1.30.0.6486

Just tried Version 1.30.2.6563 on Docker. Same issue. I beginning to think this will never work again.

Just tried latest 1.31.0.6654 beta docker on Linux, and HW HDR transcoding is working again for me.
