Just like what I said, in some websites, the RTMP server will change the code behind the "auth=".
Why the customer can see the same clip for serval times by the Firefox or IE browser, but the
rtmpdump can't dump the same clip using the same authorization code ? Because there are some JavaScript in the webpage of the clip, when customer click the play button, the browser will require the authorization code, after that, the RTMP server will reply the new authorization code.
It is emphasis that the authorization code is used
only for this time. So if you use the authorization code again, the RTMP server will reject the requirement.
Paw Robot just do the same thing like browser, Paw Robot will require the authorization code actively, so Paw Robot can work.
