# Description of the new process of getting to the stream #
###############################################################
# Valid URLs for new tests
# https://npo.nl/start/serie/zembla/seizoen-2015/wie-is-de-mol-2/
# https://npo.nl/start/serie/zembla/seizoen-2015/wie-is-de-mol-2/afspelen
# Step 1: Normalize the URL
# If the URL ends with /afspelen, strip that
# We need the slug in the next stepto find the productId
# Step 2: Find the productId
# In the contents of the URL is a JSON blob:
# <script id="__NEXT_DATA__" type="application/json">
# There's a list of queries in the ['props']['pageProps']['dehydratedState']['queries'] key
# In this list of queries, one is the current episode
# This one can be found by looping over queries and selecting
# the one where the key ['state']['data']['slug'] contains the last part of the URL
# In the test case 'wie-is-de-mol-2'
# We need the productId from the corresponding entry in ['state']['data']['productId']
# This looks a bit GraphQL-like, so there might be an easier way to query the productId, if we know the slug
# Step 3: Get the JWT
# With this productId we can get a player-token
# https://npo.nl/start/api/domain/player-token?productId=VARA_101372912
# The response is a JSON dictionary, with one key ['token']
# In this key is a JWT
# Step 4: Get the stream-link json
# The JWT needs to be put in the Authorization header in a POST request to
# https://prod.npoplayer.nl/stream-link
# with the following payload (for this test case)
# {
# "profileName": "dash",
# "drmType": "widevine",
# "referrerUrl": "https://npo.nl/start/serie/zembla/seizoen-2015/wie-is-de-mol-2/afspelen"
# }
# Even though the request asks for Widevine DRM, it's not always available
# At this point we don't know whether there's DRM yet
# Step 5: Get the stream.mpd from the JSON response and find out if DRM is enabled
# This returns a JSON response with a stream.mpd file in the ['stream']['streamURL'] key
# If dash_unencrypted is in this URL it's a stream without DRM and we can download it
# For all new content there most likely is DRM protection on the stream
# In that case dash_cenc is in the stream.mpd URL
##############################################################
# Differences when embedded on the broadcaster's website #
##############################################################
# The same episode is also embedded on the broadcaster's website: https://bnnvara.nl/videos/27455
# It's nice to support that too, and in the case of bnnvara.nl (and maybe more broadcasters)
# it's even easier to get to the productId
# By POSTing to the GraphQL endpoint at we can query using the id (last part of the URL)
# https://api.bnnvara.nl/bff/graphql
# {
# "operationName": "getMedia",
# "variables": {
# "id": "27455",
# "hasAdConsent": false,
# "atInternetId": 70
# },
# "query": "query getMedia($id: ID!, $mediaUrl: String, $hasAdConsent: Boolean!, $atInternetId: Int) {\n player(\n id: $id\n mediaUrl: $mediaUrl\n hasAdConsent: $hasAdConsent\n atInternetId: $atInternetId\n ) {\n ... on PlayerSucces {\n brand {\n name\n slug\n broadcastsEnabled\n __typename\n }\n title\n programTitle\n pomsProductId\n broadcasters {\n name\n __typename\n }\n duration\n classifications {\n title\n imageUrl\n type\n __typename\n }\n image {\n title\n url\n __typename\n }\n cta {\n title\n url\n __typename\n }\n genres {\n name\n __typename\n }\n subtitles {\n url\n language\n __typename\n }\n sources {\n name\n url\n ratio\n __typename\n }\n type\n token\n __typename\n }\n ... on PlayerError {\n error\n __typename\n }\n __typename\n }\n}"
# }
# The response is in the key ['data']['player']['pomsProductId']
# From this point it's possible to continue at step 3 of the description above
