示例1: CreateAndResolve

mActiveSourceBuffers->ClearSimple();
bool initMissing = false;
bool found = false;
for (uint32_t i = 0; i < mSourceBuffers->Length(); i++) {
SourceBuffer* sourceBuffer = mSourceBuffers->IndexedGetter(i, found);
MOZ_ALWAYS_TRUE(found);
if (sourceBuffer == aSourceBuffer) {
mActiveSourceBuffers->Append(aSourceBuffer);
} else if (sourceBuffer->IsActive()) {

} else {
// Some source buffers haven't yet received an init segment.
// There's nothing more we can do at this stage.

}
}
if (initMissing || !mDecoder) {

// Add our promise to the queue.
// It will be resolved once the HTMLMediaElement modifies its readyState.
