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!"?

we currently don't have a setting for this because there's no way to tell if the extra track can be substituted for the default or if it's something like commentary. we should probably add a setting for it though.

I was thinking since the iOS app is only for Apple (hence it being the iOS app!) it could have a function where if the default track is not an apple supported format (aka. AC3), it searches to see if there is an AAC track before it plays the default track.

Anyone know if this would be possible?  

 

My kids end up leaving the default AC3 track playing when they are on their iPads and it eats up CPU on the HTPC because it is transcoding.  It would be nice if the iOS apps were smart enough to select the iOS compatible AAC tracks.

at the moment we don't automatically select alternative tracks because we have no way to know if they might be commentary or some kind of special audio. something to consider in the future.

Yeah, I see your point. The 2-Ch AAC track could be directors commentary....

But I would think people would put a directors commentary at the END of their audio tracks and not first. Maybe set iOS app to play the AAC audio track instead of the default audio track only if the AAC track is the first audio track?
