How do I change from dvhe to dvh1? Using a hex editor? How would I make the appropriate changes from dvhe to dvh1. It's showing up as HDR on infuse. If you could show me how to change the value. That would be appreciated.HongyuS wrote: ↑Fri Oct 23, 2020 3:40 amI forgot to mention one very important info: Apple require the video track fourcc ID to be “dvh1” for Dolby Vision. So you need to change it manually using a Hex editor. (More info: the sample I recommended to you is “dvhe”, which cannot be played by QuickTime/Apple TV app)badrobot wrote: ↑Fri Oct 23, 2020 2:52 amI have tried MBOX demo video files on my iPad Pro, it seems that P5 can be identified as DoVi by infuse 6, but P8.1 can not.
Result:P5 play as DoVi, P8.1 play as HDR, I have uploaded these screenshots.

Furthermore, Infuse only supports profile 5. If you want to test profile 8.x, you need to copy the the m4v file to the “Files” app, and preview with it. (And you must use iPadOS 14.1 or 14.2 beta 4, or later versions, in order to support profile 8.x)
