C++ (Cpp) TimeUnit::ToSeconds Examples

Example #1

File: MP3Demuxer.cpp Project: cstipkovic/gecko-dev

int64_t
MP3TrackDemuxer::FrameIndexFromTime(const media::TimeUnit& aTime) const {
  int64_t frameIndex = 0;
  if (mSamplesPerSecond > 0 && mSamplesPerFrame > 0) {
    frameIndex = aTime.ToSeconds() * mSamplesPerSecond / mSamplesPerFrame - 1;
  }

  MP3LOGV("FrameIndexFromOffset(%fs) -> %" PRId64, aTime.ToSeconds(), frameIndex);
  return std::max<int64_t>(0, frameIndex);
}

Example #2

File: WaveDemuxer.cpp Project: Wafflespeanut/gecko-dev

int64_t
WAVTrackDemuxer::ChunkIndexFromTime(const media::TimeUnit& aTime) const
{
  if (!mSamplesPerChunk || !mSamplesPerSecond) {
    return 0;
  }
  int64_t chunkIndex =
    (aTime.ToSeconds() * mSamplesPerSecond / mSamplesPerChunk) - 1;
  return chunkIndex;
}
