Speaker
Description
This talk will provide an update on the latest developments in GStreamer Editing
Services (GES), with a special focus on the newly stabilized linear time
remapping feature. Time remapping enables powerful video effects like slow
motion, fast forward, and reverse playback by manipulating the relationship
between input and output timestamps. We'll explore how this feature has been
implemented at the GStreamer anf NLE level. The presentation will cover the core
GStreamer elements involved, the challenges we faced, and how these capabilities are exposed through GES for video
editing applications. We'll also discuss the roadmap ahead, including exploring
future work on dynamic speed changes during playback (smoothly transitioning
from normal to slow motion while playing) and other improvements to the GES
stack.
