Dolby Vision Support

This pre-release adds Dolby Vision encoding support for Windows, macOS, and Linux. I have tested it enough to know that it works, but not enough to say that it is 100% production-ready. To check out this release, clone the dvtest branch of the repository.

What's New

The script is now capable of encoding Dolby Vision! There are a few caveats, however:

1. x265 is required for encoding, because ffmpeg does not support RPU files (yet). Due to the many varieties of x265 available (as well as the binary size), I chose not to include it with the package. Download your favorite branch of x265 to use, and make sure it is named x265 (not x265-b, for example). Also be sure that it is available via PATH
2. Due to some severe memory leaks when piping ffmpeg to x265 in PowerShell, cmd.exe / bash are used to actually run the commands. This doesn't really affect speed or quality, but it does affect what type of logging and reporting options are available
3. Because x265 encodes as an elementary hevc stream, mkvmerge or similar is required to mux the video stream back into the audio/subtitle container. If you have mkvmerge available on your system, the script will automatically use it; otherwise, it must be done manually. do not use ffmpeg to remux the streams! The DV metadata will be discarded
   • Due to timestamping issues from the hevc stream, test encode audio/subs are usually out of sync. I'm looking for ways to fix this
4. The script only supports profile 8.1 for now, as it includes an HDR10 base layer. I hope to add new profiles in the future
