Workflow to add a AAC compatibility track to MKV files

[ultradj83]

Dears,
I have 361 MKV files organized in a Artist / Title folder tree.
Such files usually have DTS or AC3 or LPCM or AAC audio tracks.
For those who don't have a AAC track, I need to add it to avoid compatibility issues with some players.

I'm in difficult in determining an automatic workflow for these.

Hello!

There is something very similar to what you are looking for in MediaInfo CLI help:

Batch Processing Example

If a file C:\video\USA Holiday.mpg contains AC-3 audio, then this may be determined and used in the following C:\conversion.bat called using:

C:\conversion.bat C:\video\USA Holiday.mpg

---conversion.bat--------------------------------------------------
@echo off
: Get the codec
C:\Programs\mediainfo_cli\mediainfo.exe --Inform=Audio;%%Codec%% %1 > C:\value.txt
: Read it
for /f "tokens=*" %%A in ('type C:\miresult.txt') do set myVar=%%A
: Test for AC-3
if ".%myvar%" == ".AC-3" goto :AC3
: non-AC-3 processing follows
ffmpeg.....
goto :exit
:AC3
: AC-3 processing follows
ffmpeg....
:exit
---------------------------------------------------------------------

Hope this helps.
