[FFmpeg-user] DVD-Subtitles in matroska container converted by ffmpeg won't disappear playing with vlc

[Bernd Butscheidt]

I created this file:
http://www.file-upload.net/download-8617894/00001.mkv.html

from a TV record with the help of ffmpeg. Now I want to keep only one audio track and the subtitles doing this:
ffmpeg -i 00001.ts -map 0:0 -map 0:2 -map 0:3 -vcodec copy -acodec copy -scodec dvdsub 00001.mkv

The subtitles of the original file 
http://www.file-upload.net/download-8617897/00001.ts.html

are shown fine by any player I tested so far. With the converted one:
http://www.file-upload.net/download-8617894/00001.mkv.html

ffplay and mplayer seem to show the subtitle track as intended. 

CMPlayer/mpv didn't show the subtitles, but the devs made a fix recently, commenting that this is only a work around of a fault done by the conversion of ffmpeg:
https://bbs.archlinux.org/viewtopic.php?pid=1381609#p1381609

With vlc subtitles just seem to be put one over another and do not disappear at least when the next is to be shown. There I was told that the fault isn't with vlc:
https://trac.videolan.org/vlc/ticket/10667

But apparently, the mkv file behaves differently to the source ts formatted file.

I want to ask if this could be taken into consideration and/or this should be reported on https://trac.ffmpeg.org.
