Current state of DTS "Master Audio" decoding?
There's a lot of conflicting information out there on this subject. Most of what I've seen indicates that FFmpeg is only able to decode the lossy "core" component of DTS-HD-MA streams. But then there's dcadec[1]. Its README indicates that it is able to decode the lossless master audio streams, and that it has been "fully integrated" into FFmpeg. Can anyone clarify exactly what this means? When decoding DTS-HD-MA audio does FFmpeg automatically decode the lossless stream, or do I have to somehow tell it to do so? Are any particular configure options or libraries required to enable lossless decoding? Thanks!

You are watching too much fake news.

None, just use recent ffmpeg version, and it will decode full DTS-HD-MA just fine.
Thanks!

No, FFmpeg by default decides the lossless DTS HD Master stream.
