Support Dolby Vision profile 8.1, 8.2, 8.4, 10.1, 10.4 signaling in HLS and DASH. Adds new option `--use_dovi_supplemental_codecs` (off by default) to use SUPPLEMENTAL-CODECS in HLS and `scte214:supplementalCodecs` and `scte214:supplementalProfiles` for DASH. To maintain compatibility with existing players the current behavior of using two entries in the manifest remains the default. This will be changed in a future version where `use_dovi_supplemental_codecs` will become on by default. Adds Dolby Vision compatible brands, 'db1p', 'db2g', 'db4g', 'db4h', 'dby1' based on https://mp4ra.org/#/brands --------- Co-authored-by: Xingzhao Yun <xyun@dolby.com> |
