how do video websites such as Youku prevent video resources from being downloaded
search Baidu for an article" how Youku prevents videos from being downloaded without authorization , but there is no specific method. I"d like to ask if anyone has done this. Give me a way to realize it.
is that it mentions
." http://k.youku.com/player/getFlvPathjsontcp"
so how does the video downloaded like this play? It"s not flash, is it? But these days, many people"s mobile phones do not have flash, so how does the mobile phone prevent videos from being downloaded?
