MPD Anchors "#t=" not supporting milliseconds

Created by: fvalleeHbbTV

Media Fragments URI 1.0 specifies the usage of the "#t=" temporal clipping with: "Normal Play Time can either be specified as seconds, with an optional fractional part to indicate miliseconds," https://www.w3.org/TR/media-frags/#valid-uri-temporal (4.2.1 Temporal Dimension)

Currently dash.js is not supporting the milliseconds part, i.e if the URL contains #t=28.8 playback will start at 28s.

In PlaybackController.js, the method getStartTimeFromUriParameters() is using parseInt(): uriParameters.fragT = parseInt(fragData.t, 10) to get the t parameter but it should use parseFloat(). uriParameters.fragT = parseFloat(fragData.t)
