[FFmpeg-user] 16:9 to 2.35:1 and true HD 7.1 to DTS

[Robin van der Linden]

Hello,

about the first point, I have no idea, maybe somebody else has.
About the audio, I'm pretty sure that TrueHD is a BlackBox to ffmpeg, 
same goes for Dolby Atoms.
I'm not sure if you have access to a MacOS system, I personally run it 
inside a VM.
There is a tool called "Subler" for MacOS, which can at least transform 
a DTS source to AC3, not sure about TrueHD and other formats, but maybe 
it's worth a try. But from my understanding, TrueHD is a proprietary 
format and will most likely also not work with Subler.


Kind regards,

Robin
