dove_tool Profile 8 to 5 conversion for Mac support

[VCK02]

When playing profile 8 DV on Mac it shows as HDR10. However, with profile 5 it plays as Dolby Vision. Can dove_tool add support to convert profile 8 to 5.

No, that requires transcoding.

I have m4v file having dolby profile 8 (Dolby Vision, Version 1.0, dvhe.08.07, BL+RPU, HDR10 compatible / SMPTE ST 2094 App 4, Version 1, HDR10+ Profile A compatible). First I demux it using it mp4demuxer which gave me two files i.e. out_2.ec3 and out_1.h265. These two files I did remuxing using mp4muxer using this command in terminal : ./mp4muxer -o output.mp4 -i out_2.ec3 -i out_1.h265 --dv-profile 5 --dvh1flag 1. This gave me profile 5 file (Dolby Vision, Version 1.0, dvhe.05.07, BL+RPU / SMPTE ST
2094 App 4, Version 1, HDR10+ Profile A compatible) but video and audio are out of sync (SC attached). Noticeable change that I have noticed is change in frame rate from variable (profile 8 sc attached) to Fixed frame rate (profile 5 sc attached). Is there any solution to it or is this a correct way to do? If you need any more information let me know will share.

First, update your system and try to play that file in QuickTime.
tvOS 17 now supports Dolby Vision 8.1
If that fails, check whether your file can play as DV in the latest Infuse.
Now supports converting P8.1->P5 on the fly.
If not, and you want to dig more into this:

Regarding the frame rate problem:

If you don't want to change the frame rate at bitstream level:
mp4box -add p8.1.hvc1.mp4:dvp=5 -new p5.dvh1.mp4
