[vlc-devel] [PATCH] Detecting language of subtitles using its filename

[Luiz Vitor Martinez Cardoso]

Dear,

What about using de NAME_FILE.LANG.extension as a hint and start checking
the legend file content?

You could relatively easily use some n-gram (
http://en.wikipedia.org/wiki/N-gram) technique to detect the language.

Best regards,
Luiz.
