示例1: observableDefer
return observableDefer(() => {
log.debug("Init: Trying to call endOfStream");
if (mediaSource.readyState !== "open") {
log.debug("Init: MediaSource not open, cancel endOfStream");
return observableOf(null);
}
const { sourceBuffers } = mediaSource;
const updatingSourceBuffers = getUpdatingSourceBuffers(sourceBuffers);
if (!updatingSourceBuffers.length) {
log.info("Init: Triggering end of stream");
mediaSource.endOfStream();
return observableOf(null);
}
log.debug("Init: Waiting SourceBuffers to be updated before calling endOfStream.");
const updatedSourceBuffers$ = updatingSourceBuffers
.map((sourceBuffer) => onUpdate$(sourceBuffer).pipe(take(1)));
return observableRace(
observableMerge(...updatedSourceBuffers$).pipe(takeLast(1)),
onRemoveSourceBuffers$(sourceBuffers).pipe(take(1))
).pipe(mergeMap(() => {
return triggerEndOfStream(mediaSource);
}));
