示例1: DumpTimeRanges

void
MediaSource::GetBuffered(TimeRanges* aBuffered)
{
  MOZ_ASSERT(aBuffered->Length() == 0);
  if (mActiveSourceBuffers->IsEmpty()) {
    return;
  }

  double highestEndTime = 0;

  nsTArray<nsRefPtr<TimeRanges>> activeRanges;
  for (uint32_t i = 0; i < mActiveSourceBuffers->Length(); ++i) {
    bool found;
    SourceBuffer* sourceBuffer = mActiveSourceBuffers->IndexedGetter(i, found);

    ErrorResult dummy;
    *activeRanges.AppendElement() = sourceBuffer->GetBuffered(dummy);

    highestEndTime = std::max(highestEndTime, activeRanges.LastElement()->GetEndTime());
  }

  TimeRanges* intersectionRanges = aBuffered;
  intersectionRanges->Add(0, highestEndTime);

  for (uint32_t i = 0; i < activeRanges.Length(); ++i) {
    TimeRanges* sourceRanges = activeRanges[i];

    if (mReadyState == MediaSourceReadyState::Ended) {
      // Set the end time on the last range to highestEndTime by adding a
      // new range spanning the current end time to highestEndTime, which
      // Normalize() will then merge with the old last range.
      sourceRanges->Add(sourceRanges->GetEndTime(), highestEndTime);
      sourceRanges->Normalize();
    }

    intersectionRanges->Intersection(sourceRanges);
  }

  MSE_DEBUG("MediaSource(%p)::GetBuffered ranges=%s", this, DumpTimeRanges(intersectionRanges).get());
