Edward Hervey	a41fb3c6df	ceaccoverlay: New CEA-708 Closed Caption decoder and overlayer ... This new element allows decoding and overlaying CEA-708 Closed Caption streams over video. * Supports CDP and cc_data closedcaption/x-cea-708 streams * Uses pango to render CC stream * Support GstVideoOverlayComposition meta if downstream supports is Tested on various test files. Remains to be fixed/improved: * Switch to GstByteReader (for code safety) * Switch to GString (instead of manual pango string construction) * Move pango/rendering code outside of main 708 decoder file (so that actual CC parser/decoder can be (re)used in other scenarios). Initial patches and improvements by: * CableLabs RUIH-RI Team <ruihri@cablelabs.com> * Steve Maynard <steve@secondstryke.com> * cjun.wang" <cjun.wang@samsung.com> https://bugzilla.gnome.org/show_bug.cgi?id=704881	2018-05-28 15:29:01 +02:00

Edward Hervey	2550718f59	ext: New ccextractor element ... Allows extracting GstVideoCaptionMeta from a stream and outputs it to a standalone stream. Part of a new 'ext' closedcaption plugin, since more features are going to be added, which will depend on external dependencies such as pango.	2018-05-28 11:54:17 +02:00
