Crate viser_complexity 

Spatial, temporal, and DCT energy complexity analysis for video.

Extracts per-frame complexity metrics (entropy, inter-frame difference, DCT energy) via FFmpeg, aggregates them into segments with scene classification, and computes an overall complexity score. Also detects screen content versus natural video.

Part of the viser video-encoding-optimizer workspace.

Structs

AnalyzeOpts

Options controlling complexity analysis.

FrameComplexity

Complexity metrics for a single frame.

Profile

Full complexity profile of a video: per-frame metrics, segment aggregates, and overall score.

ScreenContentDetection

Result of screen-content detection.

SegmentComplexity

Aggregated complexity metrics over a time segment.

Enums

ContentType

Content type classification result.

SceneClass

Classified scene type based on spatial/temporal complexity.

Functions

analyze

Extracts per-frame complexity metrics and aggregates them into segments.

classify_scene

Classify a segment by its spatial/temporal complexity profile.

detect_screen_content

Detects whether a video is screen content based on complexity profile heuristics.
