</span>It may make sense to look at using libzvbi0 for the EIA-708 decoding.<br>
I've actually considered at various points switching the existing<br>
EIA-608 parser to use this and ripping out 90% of the stuff in the<br>
current cc.c. It's got a modified BSD license and we're already using<br>
it for Teletext parsing as well as for VBI slicing when doing EIA-608<br>
over analog. Would be nice to get rid of the duplicated code (and<br>
make any fixes to libzvbi if needed, where they can be shared across<br>
multiple projects).<br>
<br>
I've had to do work on CC parsing in libzvbi, VLC, and tvtime - would<br>
be great to have a single library where I don't have to keep making<br>
the same fixes across multiple codebases.<br>
<br>
In fact, if we're looking for something that can be done in an<br>
Outreachy project, moving to libzvbi for EIA-608 decoding would be a<br>
much more useful piece of work than EIA-708 parsing in general. Then<br>
if we add 708 support to libzvbi, all the consumers of that library<br>
would benefit.<br>

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?</div><div class="gmail_extra"><br></div><div class="gmail_extra">Thanks</div></div>
