  • Modify other-transcode to copy 10-bit high-dynamic-range (HDR10) metadata, extracting content light level and mastering display metadata from a HDR10 video frame input and tagging a 10-bit video stream output in Matroska (MKV) format with that information. This will also copy static HDR10 metadata from Dolby Vision and HDR10+ video streams but it will not copy additional dynamic metadata from those formats.
  • Add a --overlay-params option to other-transcode to override the overlay filter configuration applied when burning subtitles. This is useful when cropping to move a subtitle within the output boundary.
  • Add a --fdk-vbr option to other-transcode to set the numeric variable bitrate (VBR) mode for the Fraunhofer libfdk_aac audio encoder, disabling constant bitrate (CBR) ratecontrol. VBR mode 1 selects the lowest quality and 5 the highest. Please note that the libfdk_aac encoder is not normally included with ffmpeg due to licensing restrictions and the --fdk-vbr option has no effect if that encoder is not available. Via #127.
