# 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)
|

# 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
