[mythtv-users] Removing support for CEA-608 teletext subtitles

[Jim Stichnoth]

We are planning to remove MythTV support for CEA-608 based teletext
captions/subtitles, as of the 0.27 release.  That is to say, 0.26 will
be the last release with CEA-608 teletext support.

Note that this has nothing to do with DVB teletext that is commonly
used in Europe.  It also has nothing (or at least little) to do with
VBI-based CEA-608 closed captions which are provided by U.S.
broadcasters and set-top box analog output.

The main reason for removal is that there doesn't seem to be any
content currently produced with such subtitles, and hasn't been for a
very long time, and so the code to maintain decoding and rendering
support is all guesswork that complicates the rest of the code.

If anyone has samples containing CEA-608 teletext captions, or has
other concerns about this decision, please let me know.
