Some movies I download legally, contain embededd subtitles. I would like ego extract them as text files(.srt, .sub, etc) in order to view the movie on a samsung tv, which needs separate files for both movie and subtitles. I tried with VLC bout found no way to extract them, do you know about any other way? Preferably for OSX.
If your video happens to be in mp4 format then for example MP4Box can be used to demux (extract) the different types of streams (video, audio, subtitles) from it. This works only if subtitles are not actually "burned" on the video image (easy test - can you turn them off in your player? If yes then all should be well).
