That change you made (streamnumber) doesnt work :(
I switched back to the "cmd = 'mkvmerge -o "' + cleanmoviename + '" -a 1 --nosubs "' + mkvfilename + '"'" method and it works fine ?

This is my sab script log:

The problem is seen here in the log you posted:

Code: Select all

    Stream #0.1(ger): Audio: ac3, 48000 Hz, stereo, s16, 192 kb/s (default)
Language found in stream  Audio
That should be a number.

The ffmpeg output line that works in my code:

Code: Select all

Stream #0:1(ger): Audio: ac3, 48000 Hz, stereo, fltp, 224 kb/s (default)
Your line with ffmpeg output, that does not work in my code:

Code: Select all

Stream #0.1(ger): Audio: ac3, 48000 Hz, stereo, s16, 192 kb/s (default)
... so the difference is the #0:1 versus #0.1 ... the : versus .
:-[

Solution: a regular expression

Code: Select all

re.findall(r"[\w']+", thisline)[2]
Proof that that works:

Code: Select all

>>> re.findall(r"[\w']+",  'Stream #0:1(ger): Audio: ac3, 48000 Hz, stereo, fltp, 224 kb/s (default)' )[2]
'1'
>>> re.findall(r"[\w']+",  'Stream #0.1(ger): Audio: ac3, 48000 Hz, stereo, s16, 192 kb/s (default)' )[2]
'1'
>>>

I'll put that in the code

Got some problems with permissions after mkv got finaly renamed back to original name. (OMV System with aufs pool)
So i added a chmod option, works fine:

Code: Select all

# Delete original mkv, rename new one to original name and chmod it
	print "Cleaning up"
	os.remove(mkvfilename)
	os.rename(cleanmoviename, mkvfilename)
	os.chmod(mkvfilename, 0777)
Maybe others can also need it.
Have no experience with github, so no idea how to add something like that, sorry :)

*EDIT*
I think i got pulled on your fork :)

Hi,

I have made a few alterations to the script. One thing I would like to know is, if it is possible to set the audio track name to

Code: Select all

languageName - codec channels
eg. English - Dolby Digital 2.0

and also set the container title to the movie title or episode number and title

You can try on the CLI with ffmpeg. If that works, you can put it in the script.

In other words: show how you do that with ffmpeg. Then I can help with the script

I basically added the languageName variable, and some CLI flags to the mkvmerge operation

I cannot find motivation for this. Or ... do you offer euro's to investigate and develop it?
