mmdtsdec - Error: Failed to open input audio.dts

[tlpbsd]

Running MakeMKV 1.7.9 on Linux. Attempting to create an MKV with the FLAC profile resulted in an endless stream of DEBUG errors, so I set the profile to 'default' and successfully created the MKV with the original DTS-HD audio undecoded.

I demuxed this track and attempted to feed it to 'mmdtsdec', but I get this error:

mmdtsdec -d ~/.MakeMKV/dtsdecoderdll.dll audio.dts audio.wav
Error: Failed to open input audio.dts

The Windows version seems to work under wine, although I did get these errors toward the end:

fixme:service:scmdatabase_autostart_services Auto-start service L"ArcSec" failed to start: 2
fixme:process:WTSGetActiveConsoleSessionId stub
fixme:ntdll:NtSetInformationToken unimplemented class 12

DEBUG: code=00000000 src=sa0JtbUW]c500tHc:213132123
Error: Failed to decode

The resulting WAV file does appear to be intact, with the appropriate length, so I'm not sure what exactly failed.

Any reason why the Linux version is refusing to even open the DTS file?

Thanks!

It should work. Do you get any messages with -v flag?

Code: Select all

mmdtsdec -v -d ~/.MakeMKV/dtsdecoderdll.dll audio.dts audio.wav

Please confirm that your input file is a raw demuxed DTS stream.

Nothing changed with -v. Here is some output from MediaInfo (and the mmdtsdec command again). Seems Linux specific, since the Windows version will open it and decode it, even though it says the decode failed at the very end (I've confirmed the resulting Windows mmdtsdec WAV is at very least fully intact, but maybe it's just the core audio?)

I've tried specifying the full path to audio.dts, but nothing changes. The file is readable (rw-r-r) and owned by the user issuing the command.

Works on another movie I just copied with MakeMKV -- first time I've had it work (I think this is the third or fourth disc I've tried). However, it also says 'Failed to decode' at the end, like the Windows version does:
