[FFmpeg-user] How to correctly set "-audio_service_type hi"?

[André Weidemann]

Hi,

I'd like to transcode a TS file containing several streams. There is one 
video, 3 audio and one subtitle stream.

I'm using ffmpeg version 3.4.6-0ubuntu0.18.04.1

One of the audio streams is descriptive audio for the hearing impaired.
Now I'd like to mark it as such in the newly created mkv file. ffmpeg 
only flags the subtitle stream as hearing impaired, but this was marked 
in the input file already...

Does anyone know how to specifiy the stream that should be marked?
I'd like to mark stream 0:2.

Thanks in advance
  André


This is my commandline:

ffmpeg -y -vsync 0 -hwaccel cuvid -i 00001.ts  -ss 00:00:00.435 
-metadata title="SomeDescription" -metadata:s:a:1 language=deu 
-metadata:s:a:2 language=deu -metadata:s:a:3 language=deu 
-metadata:s:s:4 language=deu -map 0:0 -map 0:1 -map 0:3 -map 0:4 -map 
0:2 -b:v 2M -c:v h264_nvenc  -c:s dvdsub -c:a copy -audio_service_type 
hi -preset slow  1.mkv

ffmpeg prints the following for input and output:
