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

[André Weidemann]

Hi,




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

One of the audio streams is descriptive audio for the hearing impaired.


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 prints the following for input and output:

Input #0, mpegts, from '00001.ts':

Stream mapping:

I'd like to transcode a TS file containing several streams. There is one video, 3 audio and one subtitle stream. 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... 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 Stream #0:0[0x13ed]: Video: h264 (High) ([27][0][0][0] / 0x001B), yuv420p(progressive), 1280x720 [SAR 1:1 DAR 16:9], 50 fps, 50 tbr, 90k tbn, 100 tbc Stream #0:1[0x13ee](deu): Audio: mp2 ([3][0][0][0] / 0x0003), 48000 Hz, stereo, s16p, 256 kb/s Stream #0:2[0x13ef](mis): Audio: mp2 ([3][0][0][0] / 0x0003), 48000 Hz, stereo, s16p, 256 kb/s Stream #0:3[0x13f2](deu): Audio: ac3 ([6][0][0][0] / 0x0006), 48000 Hz, 5.1(side), fltp, 448 kb/s Stream #0:4[0x13f1](deu): Subtitle: dvb_subtitle ([6][0][0][0] / 0x0006) (hearing impaired) Stream #0:0: Video: h264 (h264_nvenc) (Main) (H264 / 0x34363248), yuv420p, 1280x720 [SAR 1:1 DAR 16:9], q=-1--1, 2000 kb/s, 50 fps, 1k tbn, 50 tbc cpb: bitrate max/min/avg: 0/0/2000000 buffer size: 4000000 vbv_delay: -1 Stream #0:1(deu): Audio: mp2 (P[0][0][0] / 0x0050), 48000 Hz, stereo, s16p, 256 kb/s Stream #0:2(deu): Audio: mp2 (P[0][0][0] / 0x0050), 48000 Hz, stereo, s16p, 256 kb/s Stream #0:3(deu): Audio: ac3 ([0] [0][0] / 0x2000), 48000 Hz, 5.1(side), fltp, 448 kb/s
