Replace 5.1 DTS with 5.1 AAC in MKV Container with eac3to?

[darkside40]

Hi there,
i just started converting my BD's to MKV to store it on my NAS.
When i did my first steps some weeks ago i simply muxxed the DTS Audio into the MKV Container, but no i have found that it would be better for me to convert the DTS to AAC because of the size.

Now i simply could demux the DTS Streams, convert them with eac3to and then remux everything to MKV. But then i would have set all the MKV Settings again etc.

My question is now, is it possible to handover eac3to the whole mkv select the DTS Stream for conversion and let eac3to simply replace (or remux with the same settings) the MKV?
If it is possible how does the Commandline have to look like?

That's not possible. You can use EAC3TO to create the new audio, but still need MKVMERGE to mux it into the original file.

Cheers,

Please have a look at this post (http://forum.doom9.org/showthread.php?p=1495723#post1495723) where Lord_Mulder has provided an excellent example for your needs I think.

What do you mean by "remux everything to MKV. But then i would have set all the MKV Settings again etc."?
mkvmerge will copy all flags, chapters etc. from a source mkv, so you would only have to set the language for the new aac audio. And as implied by jj666 you can skip the demuxing, as eac3to can use dts-in-mkv as a source.

You can try the GUI UsEac3to 0.8.1 (http://forum.doom9.org/showthread.php?t=145574)

1) Load the mkv in UsEac3to. If your DTS track input to convert is 2: DTS ...

2) 'Track Input' -> 2: DTS, 'Output format' -> m4a, 'Add' (now you can change the quality if don't want the default 0,5)

3) You can 'Add' a second audio track (only first and last audio track will be added to the mkv output)

4) 'Run and MkvMux'. First run the audio conversion, at end send the original mkv without audio, and the converted/extracted audio/s to mkvmerge.
