How It Works
In-Browser Video Stream Trimming: Demux Seeking: Seek input stream index to start timestamp: $t_{start}$ and end timestamp: $t_{end}$. Keyframe Alignment: - Fast Mode (Codec Copy): Cuts at nearest keyframe (I-frame) index with zero re-encoding latency. - Accurate Mode (Re-encode): Decodes frames around target $t_{start}$, re-encoding seamless GOP (Group of Pictures) boundaries for millisecond precision.
