xHE-AAC / FDK2 for Android - also available on Linux soon? 2019-01-18 11:09:33 In light of CES 2019, Fraunhofer announced that xHE-AAC decoding capabilities will be part of FDK2 which is shipping with Android 9.As typical with press releases and sales-talk on conventions, etc. I'm a little confused what this means. Does that mean decoding only? Since FDK2 is going to be "mandatory" for Android 9, does that mean, that technically this will bring xHE-AAC decoding to Linux? And what about encoding? With FDK, we got an AAC encoder which proves to be pretty good. It's the only really viable option on Linux, as things like FAAC are pretty bad, and QuickTime AAC isn't available on Linux.So, allegedly, xHE-AAC can scale between 12kb/s to 500kb/s, does that mean the encoder has to provide for the entire spectrum of bitrates for that function to be available? The Sales guy suggested it is, but I kinda fail to see how that is accomplished, aside from using a plethora for streams in tandem. Or does it provide some form of interlacing, where by sending sending only the first couple samples contain a course set of values, and the more you receive, the more detailed the data is? Also, I thought that technology is rather coming from MPEG-H, rather than xHE-AAC (the container, rather than the codec itself).I got all that from this video:https://www.youtube.com/watch?v=yArrLvMYng8I found it a bit more easier to follow, by setting the playback speed to 1.25, because the monologue by the sales guy is a bit long and boring.
