What do we do with this? :)
I can see dark-green subtitles in DCP-o-matic ver.2.4.12 at top-right corner.

The main thing is to support creation of DCPs with CCAP and this DCP shows what needs to be done. It would be nice if everything worked on import too.

I believe that the link for the demo DCP in the Description section is wrong. It goes to a non-link.
Since the DCP changes from time to time, the best link is:

Furthermore, there is another ISDCF document that has a few subtle points to make in the use of Closed Captions

We should probably dig up some sites with CCAP hardware for testing. I am pretty sure Harold Hallikainen would also look over some test files.

@carl: basics are in libdcp git and ccap branch. First major difficulty is that DCP could have both subtitle & ccap, and the metadata format can't cope as all the tags for video/audio/subtitle are dumped into one parent.

@carl: perhaps this should be treated using subtitle streams; i.e. FFmpeg and DCP have multiple streams and we have a subtitle stream and a CCAP one.
