Can someone show me how to do this, if possible....
All my movies are in an MP4 container with track 1: H.264 video, track 2: 2-ch AAC audio and track 3: 6-ch AC3 audio. The second audio track (track 3) is set as default. The reason my files are setup like this is because when I download some of these files to my iPad or iPhone the first audio track must be AAC to play correctly, but I have the AC3 track set as default because I want the AC3 track to bitstream to my AVR to play surround sound when I watch a movie on my HTPC.
When I call up a movie on the Emby iOS app, the app causes the server to transcode the file because it plays the default AC3 audio file. However, when I manually switch to the 2-ch AAC track the server stops transcoding and the file direct streams (I believe?) to the iOS app. [I believe this is true because the CPU usage goes way down when I select the AAC track] I have "Play default audio track regardless of language" NOT checked.
Is there a setting in the Emby Server or Emby iOS App that will say "hey, if the iOS app is calling up an MP4 file, I should play the compatible AAC audio track and not transcode an unsupported audio track because obviously I am on an Apple device!"?
