Description

I used to use youtube-dl for these types of VHX/vimeo sites - however I can’t seem to get them working anymore. Any thoughts?

[remitamine]

It seems easy to extract the iframe url from the video page:

generic support VHX Embeds will be added in the next version.

For anyone that makes it here and is scratching their head about this, the VHX VoD works in yt-dlp, but you do have to paste the entire long string from the embed source

ie

$ yt-dlp -Uv --cookies vhx.tv_cookies.txt -v 'https://embed.vhx.tv/videos/923926?api=1&autoplay=1&back=xxxxxxxxxxxxx&collection_id=162241&color=3b6691&context=yaddayaddayadda'

tested on Ubuntu 20 on WSL2.0 yt-dlp is up to date (2021.11.10.1)
