ReadonlytickReadonlysampledReadonlysampleTrue when the sample reached the end of the track rather than the cap, so the verdict covers every frame rather than a prefix.
ReadonlyduplicatePairs of frames sharing one presentation timestamp.
ReadonlydistinctHow many different gaps separate neighbouring frames. A constant-rate source has one, or two where the timebase cannot state the rate exactly.
ReadonlyminReadonlymedianReadonlymaxReadonlyfirst
Frame timing measured over a bounded prefix of the track's packets, in the container's own integer tick grain.
