                          How do I convert a hdmv_pgs_subtitle (which is image based) to a text based subtitle in a MKV file?

I have tried ffmpeg -i in.mkv -c:v copy -c:a copy -c:s mov_text out.mkv but that results with the following error:

    Stream mapping:
      Stream #0:0 -> #0:0 (copy)  
      Stream #0:1 -> #0:1 (copy)  
      Stream #0:2 -> #0:2 (hdmv_pgs_subtitle (pgssub) -> mov_text (native))  

    Error while opening encoder for output stream #0:2 - maybe incorrect > parameters such as bit_rate, rate, width or height
