.ts DVB with dvbsubtitles --> mkv with subtitles (wrong subtitle position)

[smellycat3]

Hello

I'd like to convert a .ts-file from a DVB-S2 recording (french channel W9 HD) to a mkv file and somehow keep the DVB (they are bitmap subtitles, not teletext ones!) subtitles optional.
Usually this works with ffmpeg in such a way:

ffmpeg -i inputfile.ts -map 0:1 -map 0:2 -map 0:3 -vcodec copy -acodec copy -scodec dvdsub outputfile.mkv

With the recording I have this also works so far, but from the moment on the dvdsub encoder has been chosen, the subtitles aren't in the correct position any longer. Instead they are in the upper left part of the picture. It guess the subtitle were be at the correct position in case the frame was 720x576 and not 1920x1080.

If someone has a hint on how to get the subtitles in the right position please help.

Thank you for your reply. BDSup2Sub works.

In my case my problem can also be solved by getting the subtitles through ProjectX (using SVT as colour scheme).

The bug seems to be in ffmpeg's '-scodec dvdsub' option.
