Hardware tone mapping failure - ashanrath - 2024-02-12
Hi all, hope someone can point me in the right direction. I've been searching the net about this for the last few days but haven't found anything that fits.
I've been using hardware transcoding for 1080 content with no problems for some time. I've got some 4k HDR media but have only previously tried to play it on clients that can handle it via direct play. I've been debating just keeping a single version of each movie, keep the 4k, delete the 1080, and rely on transcoding for any clients that can't handle it. I've been mostly wanting to do this due to Radarr>Jellyfin issues, but that's another topic.
Everything is working fine for me so far, except for tone mapping. My server can comfortably handle several 4k HWA transcodes simultaneously with the below config. However, if tone mapping is enabled, I just get a blank green video. Audio is fine, burned in subtitles are fine, but just a blank green video. If I disable tone mapping the video also works fine, though of course it's looking washed out.
I've tried grabbing the latest jellyfin-ffmpeg release, updating drivers, etc. No luck so far. I hope I'm missing something painfully obvious?
Screenshot and transcode logs attached for reference, server details below.

It's an Intel driver issue. They broke the Windows driver in 5186_5234 and the latest 5194_5252.
Downgrading to 5085_5122 should fix the problem.

Oh, you beautiful bastard. I knew I'd had it working previously. Downgraded and all fixed up. Thanks very much for the assist!
