Module util 

Structs

ProbeInfo

Subset of media properties extracted via ffprobe.

Functions

check_media_binaries

Fail fast at startup if the configured ffmpeg/ffprobe binaries aren’t runnable. They are required for recording, clip/snapshot export, sampling, and indexing; a missing binary otherwise surfaces only later as silent per-camera failures (cameras stuck “connecting”, empty timelines).

ffprobe_file

Probe a media file for duration and video stream properties.

ffprobe_stream

Probe a live stream URL (RTSP-aware) to confirm reachability and read codec/dimensions.

parse_rfc3339

Parse an RFC3339 / ISO-8601 timestamp (accepts a trailing Z) into UTC.

parse_segment_time

Parse a UTC segment start time from a filename like 20260613_120500.mp4.

slugify

Turn an arbitrary string into a safe lowercase slug for camera ids / path segments.
