DTS audio not detected

[zenny]

Hi, I am trying to replace DTS with ac3, but the script says it does not have DTS audio. Hmmm!

ERROR: There are no DTS tracks in 'VideoWDTSaudio.mkv'.

[choekstr]

the script checks for A_DTS line in the output of mkvmerge. here is the specific line:
mkvmerge -i "$MKVFILE" | grep -m 1 "audio (A_DTS)" | cut -d ":" -f 1 | cut -d " " -f 3

Can you run mkvmerge -i VideoWDTSaudio.mkv and let's see what the DTS line looks like?
My guess is the mkvmerge output has changed to be DTS instead of A_DTS. If that is the case, you can just modify that line (~396) accordingly.

Thanks, I have a file that mkvmerge reports as:
Track ID 1: audio (DTS-HD Master Audio)

changing the line in the script to DTS-HD Master Audio)

Solved it for me as well.

I just change the link 408 to this:

DTSTRACK=$(mkvmerge -i "$MKVFILE" | grep -m 1 "${AUDIOTRACKPREFIX}DTS" | cut -d ":" -f 1 | cut -d " " -f 3)

Notice the removal of the trailing ) in the grep command.

I just submitted this: #121

It's just a case of keeping up with the subtools and their changing output. We tried to make it as generic and match as many things as possible but when mkvmerge changes types, new DTS modes are added, etc then tweaks are required.

way to dig in and determine the changes required for this format...
