CSS and VOD
A series of solutions that combine live streaming and VOD are provided based on the unified ecosystem of CSS and VOD.
Live recording: Live streams can be saved to VOD after packaging (without modifying the audio and video data or timestamps). This allows you to archive your live streams, post-process live content, as well as distribute recorded live streams on demand.
