ffmpeg mkv to mp4 video passthrough audio stereo

Fortunately using this method means that you only have to re-encode the audio not the video so only takes a few minutes even on an old core i5. For me this made the soundtrack much louder and especially made a difference to dialog. has the exact same video with no changes, but audio re-encoded to AAC stereo. The below script takes a DTS audio track from a file and re-encodes it to 5.1 channel AC3. Since Apple doesnt natively support MKV, Im forced to remux into MP4. The only solution was to re-encode the audio track using FFmeg.

There was no solution I could find within the applications or the audio systems to correct this.

mkv file that I could play on Xbox One X which had clear/loud audio, would direct play (including 4K HDR) and had no audio sync issues. mkv files through the below script I had an. As the Xbox One X fully supports Plex using AC3 the solution below also solved many audio sync issues for me that seemed to occur when the DTS audio was being transcoded. You may also find that If you don’t have a true 5.1 channel audio system (such as some soundbars) you may find that DTS soundtracks are quiet when used with media players suck as Kodi, Plex or Windows media player.

This means that Plex will then have to transcode the audio which can mean lots of buffering or in the case of the Xbox One X will force 4K video to be transcoded to 1080p. Some Plex players do not give Plex full access to the OS/hardware for DTS decoding.
