Why shouldn't you be able to "grab the "language" field"?

As per your question, I have to edit the script as follows, that was my fault.
I should have mentioned that language field has relation with srt field.

Code:
for file in *.mp4
do
/root/bin/ffmpeg -i $file \
-i $(basename "${file/.mp4}").bos.srt \
-i $(basename "${file/.mp4}").dan.srt \
-i $(basename "${file/.mp4}").slo.srt \
-i $(basename "${file/.mp4}").swe.srt \
-map 0:v -map 0:a \
-map 1 -map 2 -map 3 -map 4 \
-c:v copy -c:a copy -c:s copy  -metadata:s:s:0 \
language=bos -metadata:s:s:i language=dan -metadata:s:s:(i+) 
language=slo -metadata:s:s:(i++) language=swe "${file/.mp4}")_output.mp4
done

tag of srt extension refers to language. If it finds *.bos.srt, it will put language=bos , bosnian language etc.
if it finds slo.srt, language should be language=slo etc.. Metadata nr increases as more srt file is found as it goes.

I am sorry again

So it is different from what you posted first?

No, not much... Language names are variable and connected to found srt files but not a big problem Rudic. Thank you so much for your support. I will find a way to sort the last part.


Kind regards

Given the language code is the same in filenames and the metadata specification, try

Code:
for file in *.mp4
  do    printf -vINCLUDE -- "-i %s "  ${file/.mp4}*.srt
        T1=( ${INCLUDE//-i} )
        T2=( ${T1[@]%.*} )
        for (( i=0; i<${#T2[@]};i++)) do        ML=$ML" -metadata:s:s:$i language=${T2[i]#*.}"
                                                MP=$MP" -map $((i+1))"
                                       done
        echo /root/bin/ffmpeg -i $file "$INCLUDE" "$MP" "$ML"
        unset ML MP INCLUDE T1 T2
  done
/root/bin/ffmpeg -i FILE1.mp4 -i FILE1.dan.srt -i FILE1.slo.srt  -map 1  -map 2   -metadata:s:s:0 language=dan -metadata:s:s:1 language=slo
/root/bin/ffmpeg -i FILE2.mp4 -i FILE2.bos.srt -i FILE2.dan.srt -i  FILE2.slo.srt -i FILE2.swe.srt  -map 1 -map 2 -map 3 -map 4    -metadata:s:s:0 language=bos -metadata:s:s:1 language=dan  -metadata:s:s:2 language=slo -metadata:s:s:3 language=swe
/root/bin/ffmpeg -i FILE3.mp4 -i FILE3.bos.srt -i FILE3.dan.srt -i  FILE3.swe.srt  -map 1 -map 2 -map 3   -metadata:s:s:0 language=bos  -metadata:s:s:1 language=dan -metadata:s:s:2 language=swe

Dear Rudic,
All ok now. I put space between map and $ sign in here, (as you did also) :
Code:
MP=$MP" -map $((i+1))"

Then, I had to change below part as language info was not giving the same result with yours:
Code:
language=${T2[i]#*.}"

to:
Code:
language=${T2[i]#.}"

Thank you so much again.

Kind regards
Boris
