示例1: lock
void
MediaEngineDefaultVideoSource::NotifyPull(MediaStreamGraph* aGraph,
SourceMediaStream *aSource,
TrackID aID,
StreamTime aDesiredTime)
{
// AddTrack takes ownership of segment
VideoSegment segment;
MonitorAutoLock lock(mMonitor);
if (mState != kStarted) {
return;
}
// Note: we're not giving up mImage here
RefPtr<layers::Image> image = mImage;
StreamTime delta = aDesiredTime - aSource->GetEndOfAppendedData(aID);
if (delta > 0) {
// nullptr images are allowed
IntSize size(image ? mOpts.mWidth : 0, image ? mOpts.mHeight : 0);
segment.AppendFrame(image.forget(), delta, size);
// This can fail if either a) we haven't added the track yet, or b)
// we've removed or finished the track.
aSource->AppendToTrack(aID, &segment);
// Generate null data for fake tracks.
if (mHasFakeTracks) {
for (int i = 0; i < kFakeVideoTrackCount; ++i) {
VideoSegment nullSegment;
nullSegment.AppendNullData(delta);
aSource->AppendToTrack(kTrackCount + i, &nullSegment);
}
