Description

Cannot download any videos from AMC's website even with MSO login. Tried multiple videos, none on the website work.

Same error from UK with no MSO login.

This was returned with the 404 response to the API URL https://content-delivery-gw.svc.ds.amcn.com/api/v2/content/amcn/AMC/url/shows/61st-street/episodes/season-1-man-on-fire--1053948 :

{
  "error": {
    "isRedirect": false,
    "parameters": {
      "network": "AMC",
      "tenant": "amcn",
      "mocks": false,
      "device": "web",
      "headers": {
        "amcn-user-state": "{\"entitlements\":[\"amc_unauth\"],\"device\":\"\",\"mvpd\":\"\"}"
      }
    },
    "url": "/shows/61st-street/episodes/season-1-man-on-fire--1053948",
    "msg": "This ID returned a 204"
  },
  "status": 404,
  "success": false
}

It would be useful to see what the API URL returns if you paste it into the address bar of your browser when playing the show.

Fetching the API URL is the first thing the extractor does. It doesn't have any code for extracting the Authorization token, which from the look of the site JS might be returned from the MSO login as the access_token in a response cookie. It seems to have become a bit OAuth2-ish. This is potentially addressed by the AdobePassIE class that is an indirect superclass of the AMCNetworksIE extractor, but I don't think the necessary code is ever called.

Has this ever worked recently? I think we have the issue from #30182:

• video host changed from ThePlatform to BrightCove
• content is DRM-protected (WideVine ?).

Obviously the second point limits the utility of addressing the first. However Fairplay DRM was used with ThePlatform before and the links could be modified to access unencrypted content.
