[LINUX] Remove unwanted audio+subs

Hey guys,
i found some scripts that "can" do this, but nothing works really well or stable.
Most of them uses mkvmerge/mkvtoolnix what is the best way i think.
Some of them just removes track1 what is not everytime the correct language.
So the script has to search for language codes.
I can not imagine that nobody here is interested in something like that
I have ~600 movies using around 5,5TB space, i already removed english audio tracks by hand and saved arround 500GB space !!!
In my case it would be great to post process this:
>Only MKV files and minimum file size like 3GB
>Find audio track with language "ger", remove all others
>Remove any subs, because Kodi handles that for me
>Keep chapters
>Remove old mkv when successful processed and use the same mkv name (when possible?)
Here is an example script:
http://lime-technology.com/forum/index. ... ic=22410.0
I cant get that one running, it doesnt find any tracks ...
Thanks !!!

So a plain script. not a SABnzbd post processing script?
Find German audio (and subs):
Code: Select all
ffmpeg -i *.mkv 2>&1 | grep -i Stream.*ger
Does that work for you?
Code: Select all
$ ffmpeg -i *.mkv 2>&1 | grep -i Stream.*ger
Stream #0:1(ger): Audio: ac3, 48000 Hz, stereo, fltp, 224 kb/s (default)
Stream #0:3(ger): Subtitle: dvd_subtitle (default)
Stream #0:4(ger): Subtitle: dvd_subtitle
Stream #0:5(ger): Subtitle: ssa

OK. So just for new downloads.
What are you going to do with all the existing downloads? Leave them that way?

You mean my already downloaded series/movies ?
They are already demuxed by hand

You have done it manually? How?
This is what works for me:
Inspection of the Audio (and Subtitle) Streams:
Code: Select all
$ ffmpeg -i movie-Ger-Jap-Dub.mkv 2>&1 | grep -i -e Audio: -e Subtitle:
Stream #0:1(ger): Audio: ac3, 48000 Hz, stereo, fltp, 224 kb/s (default)
Stream #0:2(jpn): Audio: ac3, 48000 Hz, stereo, fltp, 224 kb/s
Stream #0:3(ger): Subtitle: dvd_subtitle (default)
Stream #0:4(ger): Subtitle: dvd_subtitle
Stream #0:5(ger): Subtitle: ssa
Stream #0:6(eng): Subtitle: ssa
German Audio is 1, so leave that in. Remove all subs:
Code: Select all
$ mkvmerge -o new2.mkv -a 1 --nosubs movie-Ger-Jap-Dub.mkv

Yes: only German audio, no subs.
Is that what you want?
What must be the name of the new MKV?
How does Kodi find the needed subtitles? (And why are Kodi's subtitles better than the ones delivered in the MKV?)

I have done it manually with mkvmerge on my windows system, everytime i downloaded a movie.
The name should be the same as original downloaded, after successful demuxing other pp script should start (nzbToCouchPotato)
Maybe the name doesnt matter, but just the demuxed mkv should stay. (Demuxing movie.mkv to movie_tmp.mkv -> OK -> Rename back to movie.mkv, overwrite?)

You are right, subs can stay, makes no sense.
Works great:
Code: Select all
ffmpeg -i movie.mkv 2>&1 | grep -i -e Audio: -e Subtitle:
Stream #0:1(ger): Audio: dts (DTS), 48000 Hz, 5.1(side), fltp, 1536 kb/s (default)

Another idea what would be really great, i dont think its a big deal.
Attach movies nfo to the mkv, mkvmerge command should be this one:
"--attachment-mime-type" "text/plain" "--attachment-name" "movie.nfo" "--attach-file" "/location/movie.nfo"

Let me know the result.
Can you give more info about the .nfo file? What does it contain? Is there always just one .nfo, in the same directory as the .mkv?

I will.
Yes, normaly there is the mkv and just 1 nfo, thought it would be great to attach it to the mkv for future investigastions

So .. works great and fast, is it possible to auto delete the old mkv and just keep cleanedmovie.mkv ?
Or directly overwrite the original one and dont creating a new mkv ?
Now i have 2 mkvs in my dir, i think SickRage doesnt like that.
*EDIT* Just inspected code, i think its already on your TODO list ?
