I used FFMPEG which is freely available to Windows, Mac and Linux users to code my HEVC files and to add the necessary HLG and Rec2020 flags which will trigger HDR TVs to play automatically the content in HLG. Here’s an example command line (make sure you download the 10-bit version of x265lib.

Btw, after much testing, I just figured out a solution using 1.2.1 and the piping out functionality (I couldn't find that feature in R2) First, the program that I'm piping to is a build of ffmpeg that supports 10bit x265. (1) In the broadcast television standard represented by Rec. 601 (including BT.709 / BT.2020), the value range of Y is 16-235, and the range of U and V is 16-240.

May 02, 2016 · If you have a very recent version of ffmpeg, you can use the brandnew colorspace filter which adds full high bitdepth and bt2020 support. On the other hand doing a 601->709 conversion and then encoding it as 2020 seems rather oddball either way, so something is crazy anyway.
Apr 08, 2019 · This is simply for videos using the BT.2020 color primaries. Please read the new article for saving HDR. I have historically been using the older x264 mp4s for my videos, as it just works on everything. However most devices finally have some native h.265 decoding. (As a heads up h.265 is the specification, and x265 is encoder for it.
