[vlc-devel] [PATCH] Detecting language of subtitles using its filename
drakorg at gmail.com

You mean peeking into the subtitles contents and detecting the language
I don't like the idea too much because it's error prone. Even chrome's
language detector fails from time to time.
Secondly, and I think most important, this technique is not limited to text
subtitles. It's also used with graphical subtitles (.ass, .sup, .sub+.idx).
Of course someone could suggest automatically OCR'ing, but I wouldn't
seriously consider getting into that either.
Just my opinion,
