Information on this media
While Gstreamer does have support for multiple subtitle formats, Closed Caption (CC) support was always missing until now. This talk will explain what makes CC unique compared to other formats, what new API and elements have been added to help handle it, and what remains to be done to bring it to the same level of support as other subtitling formats. Edward Hervey has been contributing to the GStreamer project for the past 14 years, from core components to high-level projects such as the pitivi video editor. Currently a Senior Engineer at Centricular, he has helped numerous clients in current and past companies to make the most out of GStreamer in various areas. He is currently in charge of Continuous Integration and overseeing QA infrastructure for the GStreamer project.
