Making url 1 click downloadable for YouTube

[nadermx]

I'm running youtube-dl from a python script. Trying to emulate what keepvid and savefrom do, refrencing this issue, I noticed that when I run youtube-dl via command line with the -g attribute it gives me a url that if I put &title=whatever I can make it a 1 click downloadable show it.

But when I try and run to get the same url via forceurl in my python script none of the urls work that way, and they differ from the output url from -g.

Is there a different command I am suppose to use to emulate the -g and if so is there any way I can have it in one run show all the formats? Or do I have to run a new instance for each format?

No difference. -g == forceurl. All formats are available in JSON output.

What I don't understand is when I do forceurl I get a url like this

And this url works as a 1 click if you add title (obviously if it hasn't expired),
but when I do json output, I get a url like this

As you can see there is a difference of params in the url, as well as order of the urls in the second one that is given by the json output. And the 2nd one does not work as a downloadable.
