From 5b71cd8af9a4937ed72bfd50d44a2ad33d9edf76 Mon Sep 17 00:00:00 2001 From: nyanmisaka Date: Thu, 3 Aug 2023 06:24:02 +0800 Subject: Expand AMD VA-API Vulkan filtering support to Polaris/gfx8 ROCm OpenCL runtime is not needed anymore when using HDR tone-mapping on Polaris/gfx8. This change requires jellyfin-ffmpeg5 5.1.3-4 or jellyfin-ffmpeg6 6.0-5 or newer versions.
