This 2017 tool produces code that will work on eBay now and beyond eBay's June 2017 Ban on Active Content.
(eBay does not accept embed code directly from YouTube or Vimeo,
and will also block active content within item descriptions from June 2017 onward.)
27 May 2017 - eBay will eventually have their own method for displaying YouTube videos, which may not be available in time for their Active Content ban in June 2017. While waiting for eBay's solution, this mobile-friendly and eBay-compliant video "thumbnail" looks just like the real thing, complete with cover image and start button. When clicked, the real video will open by itself in a new page in full-screen mode, without the distraction of competing videos, and in full compliance with eBay Links Policy. Use this clickable pseudo-video in your listings for either YouTube or Vimeo videos.
04 Aug 2017 - eBay's solution may not be available until 2018. This is currently the best method.
09 Nov 2017 - YouTube videos of any type have failed to work within eBay's Mobile App since mid summer. This problem is ongoing and eBay has not provided any estimate of when, or if, the App will allow YouTube scripts to run. YouTube uses scripts to determine device compatibility when choosing a video format to load.
Upload Video to YouTube, and then
Choose which source to use:
1 Video number
2 Video URL address
3 "Share" link
4 "Embed code"
