https://cinepedia.com/category/accessibility/ ... Closed Captions and Closed Subtitles are text-only recitations directed to a personal display, and not visible to the general audience (i.e., off-screen). SMPTE ST 428-10 DCDM Closed Caption and Closed Subtitle sets forth a set of constraints applied to Timed Text essence for the off-screen applications of Closed Captions and Closed Subtitles. The constraints essentially limit the interpretation of positioning elements in the XML document to the vertical position. The same closed caption and closed subtitle constraints applied to SMPTE off-screen Timed Text may also be applied to CineCanvas™ off-screen applications in Interop distributions. Unlike Open Subtitles and Open Captions, Closed Subtitles and Closed Captions may carry up to six (6) versions of off-screen Timed Text Track Files in one Composition, one language per Track File. It is up to the personal display provider to provide on-demand access to the multiple track versions. The packaging of off-screen Timed Text Track Files deserves special attention, as explained in the Reel Flexibility for Timed Text section. Interop DCP Closed Caption files are a constrained version of the CineCanvas format. The constraint documentation is available on the Interop DCP page. |

Carl - comments marked as 'private' - who's allowed to see them?
|
|
It should be only the bug reporter and anyone with "developer" access or more; that's currently me, you and Manuel. |
|
Good, thought I might be a bit more careful with long SMPTE excerpts.

Done in and around 1db0293ad36605da9ca8daa8736ef581f4f6a34e |

Okay, once a test version including this is up, I will send Harold Halikainen a test DCP to try this. Isn't it fascinating to spend work on implementing features that only one out of 7 BILLION people is going to use?
|
|
Great, just running unit tests then I'll put up a test version. Surely at least 2 people will use it! |
|
If I may be of assistance I work a theater with Dolby, GDC, and Christie servers, I'm happy to test closed cap DCPs for you - its a feature I'm actually looking to use myself (so yes, I'm that 1 in 7 Billion!) |
|
@chucky3456 that would be great! Any testing you can do would be most helpful. Let us know how you get on! |
|
@carl i can confirm successful ingestion and playback of closed captions on Dolby DSS100, GDC servers, and Solaria One servers. Captions are working great! |
|
Cool, thanks @chucky3456 |
