how to get flash video stream URL from website without browser (telediario, rtve)

Question

I have before_action :authenticate_user! in the application controller, which is very efficient because it applies to all controllers but there's one page (home page) that should be available without login.

Is there a way to keep before_action :authenticate_user! in application_controller.rb (for the sake of DRY) and make an exception to allow access to just home#home to be available without authentication?

Notes:

• we could obviously remove before_action :authenticate_user! from the application controller and place it in all controllers but for 'home#home' (the downside to this is it's not very DRY)
• just a side note, but I'm not exactly sure why the /users/sign_in url is even accessible (something in devise must make it so, but I'm not sure where that mechanic lives or what it is exactly - perhaps if I found it I could add more routes to it?)

Solution

I am the webmaster of Descargavideos.tv I have implemented a script to do what you need, but in php. I cannot help you with scripting it in bash but you can look at the php script here and use it too make the bash script https://github.com/forestrf/Descargavideos/blob/master/secundario/rtve.php There is a lot of legacy code, code that I wrote before I knew that clean code was a thing and patches, but it works and there are lots of comments so it may be useful for what you need.
