I'm trying to get tumblr to accept video. What are the requirements of Tumblr video posts using iFrames, why do they accept some iframes and reject others. Is there something needed in meta data like facebook video?
Are there any specific examples of iFrame standards acceptable to the major social media platforms Tumblr, pinterest, twitter? EDIT - my fault i fixed the videojs iframe but any tips on video iframes within popular social media with 3rd party players is appreciated.
