VC-1 video codec decoded correctly, but not audio.

[clarkss12 304]

I have a lot of videos with the VC-1 video codec and Emby is identifying that codec and transcodes it correctly as it should.   The problem is that it also transcodes the audio codec from DTS-HD MA to just plain DTS.  All of the other videos without that VC-1 code play with DTS-HD MA.  This happens on both Emby versions.

hi, when transcoding is needed you can't put dts into the HLS protocol that we're using, so that's why the audio gets converted as well.

Thank you for that information.
