[FFmpeg-user] DTS:X and Atmos.

[Nomis101]

I know, FFmpeg does not officialy support DTS:X and Atmos. But, inspired from a HandBrake question on github[1], I just want to clarify something.
If a DTS:X or Dolby Atmos stream is copied into another container (-acodec copy), will the DTS:X / Atmos related information be fully/partly
stripped away or will it be preserved?

Thanks
