Inzwischen geht im OE2.5 so einiges an Audio/Video Formaten.
Die Box kann bis 32Bit 352K mch lesen und Wiedergeben. SPDIF und HDMI.
Audio Multichannel wird immer in 2 Kanal ausgegeben.
flac und wav habe ich bis 32B/352K getestet.
DTS-x und Dolby Atmos (bis 7.1 getestet) kann Sie auch Verarbeiten geht dann über SPDIF mit SUPER Qualität in meine DSP.
HDMI am Receiver habe ich noch nicht Versucht.
Das spielt alles im MovieCenter oder EMC ohne Probleme.
Im Quellcode habe ich den mplayer im CLI verwedet weil man da eine schöne Ausgabe bekommt.

Leider gibt die Dreambox das immer nur mit max 16Bit 48khz raus (SPDIF/HDMI)
Frage:
ist 16/48 das maximale was der CHIP/Box kann.

Und mit mplayer (ffmpeg) geht dann sogar SACD, Monkeys Audio, Opus und noch vieles mehr.
