Description of your issue, suggested solution and other information

Attempted to download link from Pandora.tv in quotes, downloader was invoked but 404 Error.
Can download by directly going to site, using developer tools to extract flv link

[Serkora]

Unless other people somehow have this working for them, this is because of the changes on the website. Some backstory for anyone interested, and a pr with a fix for everyone else. #11377

I have not used youtube-dl for this website ever, so the word "change" is only based on the current link that youtube-dl is trying to use. And have only started to look into how to download from pandora a couple of days ago.

Anyway, what I have found is that to download the file, the link must have the correct px-time and px-hash queries (in fact, everything else can be omitted, http://cdn.blabla.pandora.tv/sd/_user/blabla.flv?px-time=1481026469&px-hash=47f0a1a3e1b69161f3e7d92d29dcebb5 is enough).

How the hash is generated I, unfortunately, was not able to find on the desktop version, only that it definitely does not depend on the ch_userid and prgid, only px-time (which, in turn, depends on the runtime, but can be found as nExpiration in the desktop version of the info json), fid and probably something else (same vodUrl in the video info leads to the same px-hash, provided it was requested at the same time, fun times testing that).

However, noticing that youtube-dl uses mobile version instead, I looked into that and found that, well, it simply asks the server for the hash (POSTing the vodurl, runtime and, strangely, prgid)!
