Live MPD provides a UTCTiming source
No UTCTiming element is present. Players must then trust the device clock, and any skew on the viewer’s machine shows up as stalls or missing segments.
dash.live.utc-timingWhat this means → - Warn
suggestedPresentationDelay leaves room to buffer
suggestedPresentationDelay of 2s is under 2 segment durations (4s), leaving no room to absorb a slow segment.

dash.segment.addressingWhat this means → - Pass
Segment template variables are used correctly
Segment templates resolve to distinct URLs for each segment.
dash.segment.template-variablesWhat this means → - Pass
Segment templates declare a timescale
Segment durations are consistent with the declared timescale.

Switchable adaptation sets declare segmentAlignment
Every multi-representation adaptation set declares segment or subsegment alignment.
dash.adaptation.segment-alignmentWhat this means → - Pass
Representations in a set share a codec family
Each adaptation set holds a single codec family, so its representations are switchable.
dash.adaptation.mixed-codecsWhat this means → - Pass
Every representation declares a bandwidth
Every representation declares @bandwidth.
dash.representation.bandwidthWhat this means → - Pass
Video bandwidth rises with resolution
Video bandwidth rises consistently with resolution.
