📄 Description

Changes

These PRs rely on the tonemap_opencl filter based on the hardware acceleration of the OpenCL device, can cooperate with the NVENC HEVC decoder to perform tone mapping from HDR to SDR while maintaining a decent transcoding speed.

The current CPU-based tonemap method is very unsuitable for real-time transcoding in terms of speed.

Requirements

  • HEVC videos with HDR10(smpte2084) or HLG(arib-std-b67) metadata.
  • FFmpeg application file with opencl hwaccel type enabled. ffmpeg -hwaccels
  • NVIDIA Pascal and Turing or newer GPUs are recommended.
  • Keep the NVIDIA driver as up-to-date as possible on Windows 10.
  • NVIDIA proprietary drivers and the OpenCL runtime library are required on Linux.
  • Should get a bit better performance on Linux.
