            Bug ID: 758232
           Summary: Add support for EBU-TT-D / TTML subtitles
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: Normal
         Component: don't know
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: floobleflam at gmail.com
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

In Bug #747774 I mentioned that I'd been working on elements to support
EBU-TT-D subtitle parsing and rendering. A repository containing these elements
(and an associated library) is now up on github:

https://github.com/bbc/gst-ttml-subtitles

I'd be grateful for comments on the design, and guidance on how this code can
best be integrated.

As mentioned in #747774, it should be fairly straightforward to create a patch
for subparse that would add parsing of EBU-TT-D files, as the changes are
mainly contained in a couple of new source files that are specific to TTML.
Integrating the library and renderer, however, is probably a bit more
complicated.

More details are given on the github page.
