Description

So, as above. I saw that the website uses eu1-prod.disco-api.com to record progress, and gets the manifests for audio and video from URLs like https://dplaynordics-vod-91.akamaized.net/dplaydni/157187/1/dash/9770679004/manifest.mpd?hdnts=st=1596094561~exp=1596180961~acl=/dplaydni/157187/1/dash/9770679004/*~hmac=1b335bd50a8e1e35624d8ffc78c65fc9b5945804705fa2daa85bf776377794a8&bw_start=800.

In FF78 with NoScript, the video plays after enabling www.dplay.co.uk, src.litix.io, players.brightcove.net for JS, and allowing DRM.

Is this provider streaming different content classes, perhaps with different ineffective technical mechanisms, but using the same domain/(show|programme)/name/video/tag format?

I just tried to download different shows on dplay with youtube-dl 2020.09.20.
Interestingly it works for most of the shows (I tried about 10 different shows), but the sport ones. So, I get the "missing device id" error for EFL on Quest, Carabao Cup on Quest, and Moto GP Highlights, but not for other non-sport shows.
