PCM/atmos or Dolby MAT in a file? #509

Sorry in advance if this shouldn't be asked here.

Is it possible to encode PCM/atmos or Dolby MAT into a file? I have managed to play MEL DV + 7.1 lossless on Apple devices by far. But Apple won't passthrough TrueHD/atmos.

I learned LAVFilters can encode TrueHD to MAT. I was hoping MAT can be encapsulated into LPCM and stored in a file somehow. If this is possible, maybe AppleTV and other players that don't support TrueHD/atmos will hand it to receiver since it's already LPCM? It seems Apple decodes everything into MAT.

Any explanantion would be very much appreciated, many thanks!
