I am trying to design Twitter player cards for my podcast episodes, which are hosted on a Wordpress site. I am confused about what is supposed to go in this section:
<meta name="twitter:player" content="">
The only information I can find from Twitter about this field is that it is an: "HTTPS URL to iframe player. This must be a HTTPS URL which does not generate mixed content warnings in a web browser. Required."
So how does one know what URL to use? Are there free players available that anyone can link to in their Twitter card? Should the player be self-hosted?
My site uses the Podlove Web Player to play episodes of my podcast (example post here). I'd prefer to use that player since I've already got it set up for each of my episodes, but I don't know enough about this whole Twitter card thing to know if that is possible.
Thanks for any tips!
