I’ve been trying to extract a hdmv pgs subtitle from an mkv file and convert it
to a .srt or .ssa file to then use it with a different .mkv file
I am new at this. I’ve been searching the archives for help but don’t find
anything useful. Can I get help with the command I’m supposed to put into
terminal. I’m using a mac and subtitle extracting options are limited. I’ve
also tried using MKVToolnix/mkvextract and vobsub2srt but I get unusable binary
code files. I’ve tried converting the .sup binary files but get messed up
timing and positioning on the subtitles. I know hdmv pgs subtitles are image
based and not text based subtitles and that's what is probably causing the
issues or errors. It there a way to extract the subtitle somehow in any format
and convert it to a .srt file?
Here is an example of what I’m trying to extract

This is the command I’m using in terminal
ffmpeg -i “FILE PATH”.mkv -map 0:4 “OUT PUT NAME”.srt
I’ve tried other command variations as well and get these error messages.
Subtitle encoding currently only possible from text to text or bitmap to bitmap
Could not find codec parameters for stream 4 (Subtitle: hdmv_pgs_subtitle
(pgssub)): unspecified size Consider increasing the value for the
'analyzeduration' and 'probesize’ options
Could not write header for output file #0 (incorrect codec parameters ?):
Invalid argument
And other errors
Please help. Thanks
