### Example URLs

Site with trailer:

Manifest file: 
https://pop-iad-2.cf.dash.row.aiv-cdn.net/dm/2$O2I7YyMfsiZnMWVzSIOZdM40UxA~/87f5/ba0e/0bc1/4322-96bf-0e7f5f024e37/91f332c9-d66a-4321-9966-eeab0c0f7c81_corrected.mpd?amznDtid=AOAGZA014O5RE&encoding=segmentBase

### Description

[Amazon Prime Video](https://www.amazon.com/Prime-Video/b?node=2676882011) allows users to watch trailers, which are not protected by DRM and therefore downloadable. (even without an account)
For now, with the normal site only product videos seem to work but not trailers. --> _[AmazonStore] B07RK3CBNQ: Unable to extract data_
Applies on all regional Amazon stores. 

An example with the manifest file is shown below.
