I’m reading a blu-ray and I know its encoded with 7.1. This is a Blu-Ray with 7.1.
When I open the large m2ts, Audacity reports 4 to 6 different encodings. I picked to read the DCA encoding. I’m assuming some of them are different languages.
 is DCA I’m assuming that is the ‘DTS encoded’ track. It is marked as ‘6’ channels.
 is marked AC3 with 2-channels. Is this the other 2-channels to complete the 7.1? Because they are missing in the 1st encoding?
 is marked AC3 with 2-channels. No idea. This could be another 2-ch track.
 is marked AC3 with 6-channels. Is this a PCM track? Could be English could be another language. I haven’t tested.
 is marked AC3 with 6-channels. Could be Spanish… I dunno. Audacity did not detect language.
Regardless how is 7.1 laid out? Why is it I never see 8-channels with the FFmpeg-Audacity-Win7 setup? Or is my suspicion correct that the 1100 and 1101 tracks would be combined to create the 8-channels…?
