### Region

Belgium

### Example URLs

- https://www.vrt.be/vrtmax/a-z/kamp-waes/2/kamp-waes-s2a1/

### Provide a description that is worded well enough to be understood

The example URL is not supported.
However, using the MPEG-DASH manifest as the input URL to `yt-dlp` works as expected (without authentication).

Note that some URLs on this website are DRM protected, some are not.
The example URL given is not DRM protected.

---

Possible solution:

When navigation to the example URL, a network request is made that returns a JSON response containing the URL to the MPEG-DASH manifest. In that same response it is also indicated whether or not the content is DRM protected.

Such URL always starts with: 'https://media-services-public.vrt.be/media-aggregator/v2/media-items/pbs-pub-'

and the response body looks like:

```json
{
    "duration": 3008130,
    "skinType": "vod",
    "title": "Aflevering 1",
    "shortDescription": null,
    "drm": null,
    "drmExpired": null,
    "videoRobustness": null,
    "aspectRatio": "16:9",

    "channelId": null,
    "targetUrls": [
        {
            "type": "hls",
            "url": "https://remix.vrtcdn.be/content/vod/pl-23f6e96b-cebe-4d73-9e42-b1180a7a68eb/pl-23f6e96b-cebe-4d73-9e42-b1180a7a68eb_nodrm_6f287733-5631-4526-93cd-4c2c68014ba4.ism/.m3u8?filter=%28%21%28type%3D%3D%22audio%22%26%26FourCC%21%3D%22AACL%22%29%29"
        },
        {
            "type": "mpeg_dash",
            "url": "https://remix.vrtcdn.be/content/vod/pl-23f6e96b-cebe-4d73-9e42-b1180a7a68eb/pl-23f6e96b-cebe-4d73-9e42-b1180a7a68eb_nodrm_6f287733-5631-4526-93cd-4c2c68014ba4.ism/.mpd?filter=%28%21%28type%3D%3D%22audio%22%26%26FourCC%21%3D%22AACL%22%29%29"
        }
    ],
    "downloadUrls": [],
    "playlist": {
        "content": [
            {
                "eventType": "ONBOARDING",
                "duration": 4140,
                "skippable": false
            },
            {
                "eventType": "STANDARD",
                "duration": 3008130,
                "skippable": true
            }
        ]
    }
}
```

Using the URL below the `"type": "mpeg_dash",` works as expected.

Example: `yt-dlp 'https://remix.vrtcdn.be/content/vod/pl-23f6e96b-cebe-4d73-9e42-b1180a7a68eb/pl-23f6e96b-cebe-4d73-9e42-b1180a7a68eb_nodrm_6f287733-5631-4526-93cd-4c2c68014ba4.ism/.mpd?filter=%28%21%28type%3D%3D%22audio%22%26%26FourCC%21%3D%22AACL%22%29%29'`

It would be great to have this integrated into `yt-dlp` so that the example URL could be used rather than finding the MPEG-DASH URL using Google Chrome network tab.

### Provide verbose output that clearly demonstrates the problem

- [X] 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
- [X] Copy the WHOLE output (starting with `[debug] Command-line config`) and insert it below
