Provide a description that is worded well enough to be understood

The URLs used to use the same ID that was also used on ThePlatform, meaning that the URL could be easily transformed into a URL for ThePlatform (see https://github.com/yt-dlp/yt-dlp/blob/e5d4f11104ce7ea1717a90eea82c0f7d230ea5d5/yt_dlp/extractor/cbc.py#L244). The URL now uses an internal ID instead, which breaks the extractor. I haven't gotten around to fixing the code, but I have had the time to look into what is needed to extract the video:

• The regex needs to be changed to accept a dot in the ID (example ID: 1.7154317)
• The webpage needs to be downloaded and json code needs to be extracted (the same component needs to be extracted as in https://github.com/yt-dlp/yt-dlp/blob/e5d4f11104ce7ea1717a90eea82c0f7d230ea5d5/yt_dlp/extractor/cbc.py#L273)
• In the json code, the media ID has to be extracted, it's located in video/currentClip/mediaID
• that mediaID can then be used to construct the ThePlatform URL in the same way as before

Maybe I'll get around to taking care of this in the coming days. If anyone else wants to take care of it, feel free.

Provide verbose output that clearly demonstrates the problem

• Run your yt-dlp command with -vU flag added (yt-dlp -vU <your command line>)
• If using API, add 'verbose': True to YoutubeDL params instead
• Copy the WHOLE output (starting with [debug] Command-line config) and insert it below
