I do understand that the DTS to AAC transcode issue would cause audio transcoding, but video should direct play at 4k, not transcode to 1080 if I’m not mistaken.
Couple of things to note here.
Only UHD H.265 8 and 10-bit files are supported, UHD H.264 8-bit doesn’t work.
Also when the audio stream gets transcoded/remuxed the video will be transcoded as well because HEVC is not currently part of the HLS streaming standard the Xbox One uses. Because as mentioned earlier UHD H.264 8-bit is not supported in general and HEVC is not part of HLS your video gets transcoded to H.264 1080p.
You’ll have to use “4k” files with AAC/AC3 to be able to direct play them in “4k”.
