ptsSource

Selects how timebase: "pts" break starts are resolved. PtsSource.MEDIA_TIME uses the manifest start directly. PtsSource.ANVATO_CUE tracks Anvato timed-metadata cues from the content player — HLS ID3 GEOB frames with description Anvatos (MIME application/json) and DASH emsg events with scheme urn:anvato:es1:052016 — whose payload is a query string of the form type=cue&pts=<seconds>. A PTS break is then scheduled at the media time of the observed cue whose pts matches the break's start (±5 ms); a break whose cue has not been observed yet stays pending (surfaced once per break via the DA-ANVATO-CUE-PENDING diagnostic). SGAI only; has no effect on wallclock-timebase manifests. Mirrors the web ptsSource. Defaults to PtsSource.MEDIA_TIME.
