How to retain DVB subs in output file after encoding?

I have an input file which is basically a .ts file, it contains the 4 dvb subtitle streams inside of it(embedded inside). I am using the following command to retain the dvb subtitles in my output video.

ffmpeg -i Input.ts -c:a copy -c:v copy -c:s dvbsub output.ts

The output video doesn't have the dvb subs inside it.

I used the following command again to retain dvb subs.

ffmpeg -i Input.ts -c:a copy -c:v copy -c:s copy output.ts
ffmpeg -i Input.ts -c copy output.ts
ffmpeg -i input.ts -map 0 -c copy output.ts
ffmpeg -i Input.ts -map 0 output.ts

None of the above commands are working for me.  How can I make my output.ts video to contain dvb susbs. Regards.

Solution

  • You can use -c:s copy -map 0. The full command would look like below.

    ffmpeg -i INPUT.ts -c:v copy -c:a copy -c:s copy -map 0 OUTPUT.ts

    If the INPUT.ts file has unknown data inside, then you can use the option -ignore_unknown after -map 0 option.
