Module camera_url 

RTSP URL construction from vendor templates, plus credential masking.

Functions

anr_replay_url

Build the replay (playback) URL used by ANR to pull a [start, end] window from the camera’s ONBOARD storage. Honors a per-camera anr_replay_url_template (with {start} / {end} placeholders, filled with Hikvision-format timestamps); otherwise defaults to the Hikvision RTSP playback endpoint (/Streaming/tracks/{channel}?starttime=..&endtime=..) built from the camera’s address + credentials. Returns None when there is no template and no host/credentials to build one from. Best-effort and camera-dependent — see services/anr.rs.

mask_url

Replace user:pass@ (or user@) credentials in an RTSP/HTTP URL with *** for safe logging/display.

record_url

The RTSP URL for the stream this camera records.

stream_url

Build the RTSP URL (with credentials) for the given stream (“main” | “sub”). Honors an explicit per-stream URL override; otherwise builds from the vendor template.

validate_stream_url

Validate an operator-supplied stream URL: must parse and use an allowed scheme.
