Hello all,

Its nice to get knowledge about the existing closed captions in VLC. I am
relatively new to open source software development.
I have no idea about Licensing Terms and Conditions.But the contribution i
made till now is very less and comprises of basic structures needed for
EIA-708 captioning. The data needed for this is available in wikipedia
page. I am very sure that Wikipedia page has no Licensing terms and
conditions. The ccextractor which i based my code upon has Licensing terms,
then i'll start writing the corresponding functions again,may be from
libzvbi(if possible and legal).Any thing i missed or incorrect?

Thanks
