I think the purpose of avfilter:tmix, as it truly comes close to motion blur, is something else: frame accumulation. So its probably hard to argue for additional features in libavfilter maintainer community. The Frei0r API is stateful, although each invocation only receives the current frame, the plugin instance persists across frames. That means we can keep arbitratry internal state to achieve optical-flow motion blur: * previous frames * accumulation buffers * optical flow estimates * motion vectors we compute * temporal statistics -- You are receiving this mail because: You are watching all bug changes.
