HW / GPU Tone Mapping with FFMPEG
Hi,
Quite simply a cry for help! I'm running a Linux media server, and recently bought a cheap NVIDIA P400 ( Linux Stream Patch Applied) for HW Accelerated Remux when away from home. I want to do HDR -> SDR Tonemap on the few 4K HDR movies don't also have the blurray for. I've compiled FFMPEG with appropriate flags and managed to run: Code:
ffmpeg -hwaccel nvdec -init_hw_device opencl=ocl -filter_hw_device ocl -threads 4 -extra_hw_frames 3 -I INPUT.mkv -vf "format=p010,hwupload,tonemap_opencl=t=bt709:r=tv:p=bt709:m=bt709:tonemap=hable:format=p010,hwdownload,format=p010" OUTPUT Can anyone give me a simple 10BIT HDR -> 8BIT SDR HW Accelerated command using either Hable or Mobius? FYI Linux server, CLI only. I've spent over a week searching and trying... mainly failing! Thanks. Alex |
