Using Youtube videos in your blog or news website
About youtube videos... Say I see something interesting in a news website which contains a youtube video. (actually I might see the same video on youtube itself as well of course)... When the video finishes, there are "embed" code and a URL link.
When there is an embed code, does it mean that the original poster of that video is allowing anyone to embed that video to his website? Or does that embed thing appear no matter what, even if the original poster dont want it to appear any other website? (i never posted on youtube so I dont know)
Bottom line, can I just use youtube video freely in a news blog without getting permission, especially if I saw it in another blog or news website?
