Hi guys, Thanks for the investigation!
“Android does not support Dolby codecs.” It is true that Dolby codecs are not part of the AOSP codebase. However, if Android-based phones support Dolby codecs or not is a different story. For instance, I would assume (but cannot check) that most Android-based Samsung phones support many Dolby codecs. Again, not as easy as it seems to be at the first glance. Hope this helps. //Christof From: Sursound <sursound-boun...@music.vt.edu> on behalf of Stefan Schreiber <st...@mail.telepac.pt> Date: Tuesday, 9.

These results make a lot of sense, and are what I would expect: Android does not support Dolby codecs. This is no speculation, but specified: https://urldefense.com/v3/__https://developer.android.com/guide/topics/media/media-formats__;!!HOHtwYw!ESig7XL8V_HBOrEahq_ZxcZqYBz7sE8moN4r1g4UdxKpVq-UINAr-fWsNUcq33fTymXEZolEqLZ5czV3Tr3KTOrt$<https://urldefense.com/v3/__https:/developer.android.com/guide/topics/media/media-formats__;!!HOHtwYw!ESig7XL8V_HBOrEahq_ZxcZqYBz7sE8moN4r1g4UdxKpVq-UINAr-fWsNUcq33fTymXEZolEqLZ5czV3Tr3KTOrt$> (Chrome on Android should show the very same results. ) Interestingly, Android does natively support hevc (video codec), though restricted to level 4.1 (minimum requirement).
