Downmixing from Atmos - maintain Atmos metadata?
Posted: Mon Apr 08, 2019 2:17 pm
Description of problem or question:
Recently picked up an Roku Ultra, which can support Atmos, but only with Dolby Digital Plus (E-AC3). When I transcode an Atmos title from TrueHD, I don't see a way to maintain / extract the Atmos metadata to apply to the E-AC3 track. I don't believe (could be wrong) that the AC3 tracks that I'm passing through have the Atmos metadata.
Downmixing from TrueHD+Atmos has, to the best of my understanding, not maintained the Atmos metadata. I've been reading the forums and it seems like this was a known issue (still an FFmpeg issue?).
Was just curious if it had been solved and I can't find the solution, or if its still an issue and I should sit back and wait. Apologies if I'm just being a moron and can't find the answer that was already posted.
Steps to reproduce the problem (If Applicable):
Passthru of TrueHD
Passthru of AC3
Transcode to AAC DPLII
HandBrake version (e.g., 1.0.0):
HB 1.2.2
Operating system and version (e.g., Ubuntu 16.04 LTS, macOS 10.13 High Sierra, Windows 10 Creators Update):
Win10 x64
Intel i5 3750
16 GB ram
