Prevent Download from GetFlv

Hi,

someone knows a way to prevent Getflv from download Wowza Streaming?

we have already all the security modules, but they still download our streaming.

RTMPE Encryption might help. I’m not sure how GetFlv is dealing with live streams. Using Silverlight or HLS with Wowza DRM is one solution to your question since it is not flash based. Netflix does this.

The best you can do is use something like the upcoming Wowza Dynamic Overlays to mark the stream.

Most, if not all, RTMP rippers work on the following principle

  • You install the ripper and run it

  • You open a webpage with the player on it and connect/play to the destination location for the content

  • It then replays the GET request to get the SWF etc etc, and gets the content

The easiest way to get around this is to put your whole website under https and set up RTMPE. The ripper then can not see the HTTP requests to get the swf and when using RTMPE it can not see the requests to the server. For about $80 (for a SSL cert) this should prevent getflv and others from being able to get your content. You do need both, just using one reduces the effectiveness considerably.

You could also add single token usage, ie. when the page loads it has a token as part of the RTMP(e) URL and the token is only valid once.

Hi, thank you for the reply.

We already use RTMPE, I tried now using https but no luck. it still works

We also use a single token, a custom module that authenticate the view only once… but somehow they changed and getflv is downloading the video as they come to the player.

If you are only using a view once link and they are still contuning to download the stream then I would suggest your view once code is not working correctly, and perhaps using HTTPS has not been done correctly.

If all techniques are implmented correctly blocking downloaders does work.
