[FFmpeg-user] Copy across core DTS audio

Fri Apr 17 12:10:43 EEST 2020

thank you again for taking the time to help me.  Also thanks for the useful
tips.  This is steep learning curve to code for FFMPEG, but starting to
understand the syntax now.  So I tried your solution and unfortunately I get
the same error.  As you suggest, here is the full console output.

I:\>ffmpeg -i x.mkv -map 0:0 -map 0:2 -map 0:1 -map 0:3 -c copy -bsf:a:1
