Burning/extracting subtitles

Ref thread

I'trying to convert WTV files to mkv or mp4 and at the same time burn the subtitles from the WTV file.
Reason for burning the subtitles is that the subtitle format is not supported for creating srt files(which would be my preferred solution)
I believe the format of the subtitles is some kind of bitmap format used in som european countries.

However, subtitles are recognized by MceBuddy
Subtitle 1
Language : Norwegian (nor)
Codec : libzvbi_teletextdec

But I cant figure out out to get them burned into the final video clip.
I have enabled "extracting Subtitle and Closed Captions" in MceBuddy, and as a test added
SubtitleBurn=true to all the profiles in profiles.conf.
Nevertheless, no subtitles in the final result.

If the source subtitles are in bitmap format, currently we are working on a solution to do image recognition to convert them to SRT text. However this is early stages and obviously it's dependent on the langiage.

Can you upload a few sample videos with this bitmap teletext subtitles for us to analyze? Small sample, about 100MB should be fine.

Would this work on DVD files (.vob or .mkv)? My understanding is that DVDs usually have subtitles in bitmap.

That would be a great feature addition!

Is there really no one that can answer if it is possible to burn subtitles(or even better convert to srt) if the format is
If this is not supported, thats too bad, but it is an answer and I dont have to search for this anymore.

Not currently. That's something we are still working on. It supports close captions and subtitles but you seem to have images (dvb) for subtitles which isn't text. It needs to have OCR convert to text

So converting to srt files is not supported, but is it possible to burn the subtitles directly to the final result?

You can burn SRT and subtitles to the final file but not the images. Right now all your subtitles are in image format and there is no way to accurately extract/process them.
