aka Object based audio...

ffmpeg doesn't seem able to accurately identify Atmos vs. TrueHD (etc...)

I know Mezzmo uses ffmpeg to collect media info, but it doesn't seem to get enough information to figure it out. MediaInfo seems to figure it out, although I have no idea how. I haven't poked at using other tools.

Is there a way a future release of Mezzmo could possibly identify the difference between an Atmos audio stream and channel-based TrueHD (and DTS:X?), and then assign the appropriate icons to a film based on the discovery?

Mezzmo passes it through just fine, and works. I tested it with an Nvidia Shield, and the Dolby test videos.
