推荐答案

这里存在巨大的误解...

There is a huge misconception here...

如果最终URL是blobURI(blob:https://www.youtube.com...)，则是因为MediaElement显示的实际上是

If the final URL is a blobURI (blob:https://www.youtube.com...) it is because what the MediaElement displays is actually a MediaSource Object.
They do fetch different ranges from different encodings and compose the data to be presented on the fly. This way, they are able to downgrade the quality if they see they didn't had time to fetch the upcoming part of the video.
But all the requests are clearly visible in your dev-tools' Network panel and anyone willing can actually compose themselves a full file.

再一次，这绝不是盗版保护.

So once again, this is not a piracy protection whatsoever.

还要注意，因为blobURIs是指向Web浏览器本地内存的URI，如果您可以显示blobURI的内容，则意味着保护它已经太迟了(因为已经下载并在内存中可用) ).

Also note that since blobURIs are URIs that do point to the local memory of the web-browser if you can display anything from a blobURI, it means it's already too late to try to protect it (since already downloaded and available in memory).
