Audio gets removed sometimes.

[w00druff]

Dear sanderjo,

please help when you have few minutes. Sometimes all audio tracks are removed when the audio track is in front of the video track.

Here's an example if all tracks are removed: (Before sabnzbd processing):

When the videotrack is before the audiotrack(s) everything is fine.

Can you help ?

Thanks Matthias

Bump, please help.

SAB-SafeRename is a command line program, and you show a GUI ... so I see no connection.

Futhermore: it's just a temp fork of https://github.com/clinton-hall/GetScripts/blob/master/SafeRename.py ... so I really don't what I can do for you.

Sorry my fault, im talking about mkv-process-audio-and-subs.py you made few months ago. https://github.com/sanderjo/SAB-SafeRename/blob/master/mkv-process-audio-and-subs.py

[sanderjo]

Oh, this is about the script discussed here: https://forums.sabnzbd.org/viewtopic.php?f=9&t=18666 ?

If so, via the SAB forum send me a PM with a pointer to such a NZB. (It seems github does not offer DM/PM)

Or, even beter: what is the output of:

ffmpeg -i *.mkv 2>&1 | grep -i Stream.*ger

for that problematic MKV

[w00druff]

Before pp: Stream #0.0(ger): Audio: ac3, 48000 Hz, stereo, s16, 192 kb/s (default) (forced)

[sanderjo]

I suggest that your run the script from the command line, with the video file you want to process; the stdout will show what is going on. I still don't get what the problem is.

[w00druff]

The problem is that he removes german track on this mkv instead of english. And i dont know why, the only reason i can think is that audio tracks are before video. Or because german track is 0.0, i dont know :(

Stream #0.0(ger): Audio: ac3, 48000 Hz, stereo, s16, 192 kb/s (default) (forced) Stream #0.1(eng): Audio: ac3, 48000 Hz, 5.1, s16, 384 kb/s Stream #0.2: Video: h264 (High), yuv420p, 1280x718 [PAR 1:1 DAR 640:359], 25 fps, 25 tbr, 1k tbn, 2k tbc (default)

Please read https://github.com/sanderjo/SAB-SafeRename/issues/2#issuecomment-152854779 and act accordingly.

The NZB you PMed me, contains an EXE, not a NZB. So not testable for me.

Here the stdout: (he removes ger track and keep eng track on that mkv...)

[sanderjo]

Ah:

Stream number 0
Language found in stream 0
command is mkvmerge -o "/DIR/cleanedmovie.mkv" -a 1 "/DIR/movie.mkv"

So: streamnumber is 0, but the command issues a "1" after "-a"

Source code:

cmd = 'mkvmerge -o "' + cleanmoviename + '" -a 1 --nosubs "' + mkvfilename + '"'

Big, big bug! That '1' should be 'streamnumber' (and then not in the double quotes), so (by hand, untested):

cmd = 'mkvmerge -o "' + cleanmoviename + '" -a ' + str(streamnumber) + '  --nosubs "' + mkvfilename + '"'

Can you test if that works for you?

[w00druff]

Works just fine, thanks a lot ! I have tried to remove "--nosubs" without success, can you help again ? :-) Got it working in the old script, but not in the new code.
