I am wanting to load FLV videos from S3 server into my Flash application.

  • 0

I am wanting to load FLV videos from S3 server into my Flash application. The original files will need to be protected (ie permissions set to read only for authenticated users) so the video files will be called with a signed url… I have managed to load and play non-signed url FLV’s into the Flash app.

1) Any issues I should be aware of before diving in?
2) Will I need to use the AS3 S3 library to generate signatures?
3) Can I generate 1 signature when the app loads (eg from PHP) and send this to Flash to use with each FLV file it loads?
4) Images and audio will also be loaded into the Flash app and will need to be protected also.

Thanks Stephen

  1. Yes you can play signed urls in Flash no problem…

    from reading around I have managed to answer a couple of my own questions –

    1) Yes lots!
    2) Not a good idea to sign urls from within Flash as the secret key would need to be in the SWF or loaded from PHP so could be a security risk here. It is probably best to call a PHP method on the server to generate a signed url and return the file to Flash / return the path to the file (sendAndLoad?). But this does seem like an extra step that could be bypassed somehow!
    3) Still not sure about this but I think that the signing process involves using the path to the file so each signature for each url is unique – is this correct?

    Anyone have further advice on this? Stephen
