示例1: MillisecondsToMediaTime
void
StreamBuffer::ForgetUpTo(StreamTime aTime)
{
// Round to nearest 50ms so we don't spend too much time pruning segments.
const int roundTo = MillisecondsToMediaTime(50);
StreamTime forget = (aTime/roundTo)*roundTo;
if (forget <= mForgottenTime) {
return;
}
mForgottenTime = forget;
for (PRUint32 i = 0; i < mTracks.Length(); ++i) {
Track* track = mTracks[i];
if (track->IsEnded() && track->GetEndTimeRoundDown() <= forget) {
mTracks.RemoveElementAt(i);
--i;
continue;
}
TrackTicks forgetTo = NS_MIN(track->GetEnd() - 1, track->TimeToTicksRoundDown(forget));
track->ForgetUpTo(forgetTo);
}
}示例2:
void
StreamBuffer::ForgetUpTo(StreamTime aTime)
{
// Only prune if there is a reasonable chunk (50ms @ 48kHz) to forget, so we
// don't spend too much time pruning segments.
const StreamTime minChunkSize = 2400;
if (aTime < mForgottenTime + minChunkSize) {
return;
}
mForgottenTime = aTime;
for (uint32_t i = 0; i < mTracks.Length(); ++i) {
Track* track = mTracks[i];
if (track->IsEnded() && track->GetEnd() <= aTime) {
mTracks.RemoveElementAt(i);
--i;
continue;
}
StreamTime forgetTo = std::min(track->GetEnd() - 1, aTime);
track->ForgetUpTo(forgetTo);
}
