segmentKey static method

@visibleForTesting String segmentKey(List<VideoEditorClip> clips, int i, { required Size canvas, required bool hardware, })

Everything that changes how clip i looks or sounds in the preview, as a stable string. The original file path is used (not the proxy), so a proxy finishing later doesn't invalidate segments.

Implementation

static String segmentKey(
  List<VideoEditorClip> clips,
  int i, {
  required Size canvas,
  required bool hardware,
}) {
  final c = clips[i];
