Thanks will try that and report back

You don't need extract the dts to convert to flac, but you need mux the flac to the mkv with MkvMerge.
The output file cannot be in .mkv container ?

eac3to cannot mux different files to one container.

Thanks. It makes sense now

Another query -
Is using Nero 7 AAC codec to convert DTS audio into stereo AAC the most efficient way ?
I mean Nero 7 is old, it might be using old version of AAC ?

It's not the most efficient way (if you mean quality-wise). I personally use Apple's AAC codec for all my stuff, you can search for 'qaac' if you're interested. There's a big thread at hydrogenaud.io but probably something here as well.

So how do I use qaac with eac3to ?
EDIT : Also is there a list of AAC encodes with their comparisions ? nvm got it

Strange, because I guess it can be used to mux to mkv audio and video coming from the same file (m2ts for example), and that's what Hitesh12 wanna do.

You need to use piping. The search should help you with that.

I think it can only work if you remux the whole Blu-ray folder and thus cannot choose what you mux or re-encode and then mux. At least that's what the example in the first post by madshi shows.

As mentioned by boulder, I'm using this currently -

eac3to input.mkv 2: audio.dts 2: audio.flac

Is there some other command to mux these ?

Thanks !

Another query () -

AFAIK there are different DTS codecs (DTS, DTS-HD I think)
So when I select .dts as output format, which DTS is it referring to ?

Also how do I check which DTS codec does the file has ? I don't think mediainfo differentiates between different DTS codecs

If you don't have a DTS encoder installed and you don't specify -core, you get DTS-HD if the original track is such. Otherwise you get a regular DTS track. I don't know if there is a simple way to determine which is which other than using eac3to

This is a very odd question but how do I access file in some other directory ?
Currently I'm moving files which I want to encode in the eac3to directory (Only then this works - eac3to input.mkv output.whatever) , which is not the correct way

I tried/searched but couldn't understand this piping along with all those commands.

Is there any guide (like this for eac3to) ?

It seems you first need to learn the basics of command line stuff. You might be better off using some GUI for eac3to such as the one here: http://forum.doom9.org/showthread.php?t=145574

Type the complete path between quotation marks if there are spaces in the path, for example ;
Code:
"C:\Program Files (x86)\eac3to\eac3to.exe" "H:\my video.m2ts" 2: "P:\my video sound.ac3"

This works (always type stdout.wav without path) ;
Code:
"C:\Program Files (x86)\eac3to\eac3to.exe" "H:\my audio.ac3" stdout.wav | "C:\Program Files (x86)\neroAacEnc\neroAacEnc.exe" -q 0.4 -if - -of "P:\my audio.mp4"
You will get aac in mp4 container.
-q is for quality, 1 is the maximum.

Other example with extraction from m2ts and downmix ;
Code:
"C:\Program Files (x86)\eac3to\eac3to.exe" "H:\my file ac3 5.1.m2ts" 2: stdout.wav -downStereo | "C:\Program Files (x86)\neroAacEnc\neroAacEnc.exe" -q 0.65 -if - -of "P:\my file (only sound) aac 2.0.mp4"

I'm having a problem with eac3to. I can't seem to extract the DTS-HD master audio from a BD. I can rip the BD then make an MKV then extract the audio but I can't seem to do it from my original source. I keep getting an error that says eac3to can't open the source file. eac3to gets to the end of it's 3rd Pass before giving me this error in the log.

What are some things I can do to troubleshoot? I've been using eac3to successfully for many years until recently. Recent rips of Stargate and Divergent are giving me trouble. Before that, no problems.

Did you try to extract first the DTS-HD track with TSMuxer, then to open it in eac3to ? But it's only useful if you wanna re-encode the sound, otherwise use MKVMerge.
