[MPlayer-users] softsub in .avi file

[Rickard Närström]

I have find some .avi file with embeded soft subtitles, mplayer doesn't  
seem to understand those subtitles at all.

I know that .avi files doesn't support embedded subtitles - but there  
still are there and I have succuessfully played the file with subtitles in  
windows (Windows Media Player - with VobSub installed).

The program that is used to anderstand those subtitles in Windows is  
called VobSub - but the subtitles in the file are still not vobsub - there  
is stored in plane ASCII in the file - and I can rip them out using:

$ strings filename.avi

I also get a lot of junk outpt from the abov command - and the subtitles  
alvays tend to get out very late (when about 99% of the output is already  
printed)

The output from strings - look something like this:
