Spatial Sound Support #41

Why you think this should be added: Monterey now support the spatial sound, but only seen in some others player and not yet in iina. The Dolby Digital Player 5.1 soundtrack play in spatial sound is overwhelming, would be grateful to see his feature supported in iina.

Examples of other projects that have something similar: Such as infuse player, or native QuickTime player

IINA uses MPV as its playback core. We can support some feature only if MPV supports it.

Does MPV support this feature?

Support for spatial audio is being discussed in this mpv issue https://github.com/mpv-player/mpv/issues/9252

I'm trying to play spacial audio (Dolby's test videos) on my m1 16'' MBP with PowerBeats Wireless 3 (listed as supported on Apple's website), but using QuickTime Player or Safari, the Dolby Atmos track seems to be played as if to a speaker, i.e. left instruments are hard-panned to left and vice versa, and there are no binaural mixing or processing. Is this the intended behavior?
