subtitles conversion question

[François Patte]

Bonjour,

I have some films in mkv format with many subtitles tracks :  
hdmv_pgs_subtitles

I can extract these tracks and I want to convert them in srt text 
format.

I use a java script (found on the web) BDSup2Sub512.jar which can 
convert the hdmv_pgs files in two files: one has extension .idx the 
other one the .sub extension.

I found this web site:

https://subconverter.com/convert-sub-idx-to-srt-online

Which I can use to convert these two files in a .srt file. So far, so 
good!

Is there a tool on linux which could do the same job?

Thank you.

mplayer may be able to. From man mplayer:

-dumpsrtsub (MPlayer only)
              Convert the given subtitle (specified with the -sub  option)  to
              the time-based SubViewer (SRT) subtitle format.  Creates a dump‐
              sub.srt file in the current directory.
