Video Card - Approved & working in Validator but not on Twitter?


#1

We recently implemented twitter card support to help feed in live broadcasts (m3u8). Two weeks ago our links were approved, showing correctly in validator tool and even working fine on twitter.com

As of late last week, our cards no longer work when viewing them on Chrome or Firefox on twitter.com. The cards still show as intended on the validator tool and when viewing them on twitter.com from Safari (probably because safari natively supports m3u8 - I also read something about iframe’s now being sandboxed, which could make sense to the failing since our video player falls back to flash for other browsers).

Can you advise why it would be working on validator tool but not twitter.com itself (aka feeds/profile). What’s the fix?

Here is demo link to see what I am referring to (place in validator tool and then try pasting it as a tweet). It cycles through various feeds so there should be no problem with caching.

Same problem here. And yes the problem comes from the fact that twitter now puts a sandbox in the iframe element. See this post: Player Card bug
