This browser does not support video playback



There is a problem playing videos using Twitter Embedded Timeline. I have a Win 7 / IE11 platform and all mp4 videos uploaded to Twitter that display in any timeline display the message “This browser does not support video playback.” What is the solution to having videos run? It looks like Twitter retiring of MP4 video output support is already in place (Retiring MP4 video output support on August 1st 2016). I ask that if anyone has a solution to please post.

I noticed a difference between videos (not vine or GIF) that play on Twitter’s timeline and mine. The file that contains video variants is a .VMAP on Twitter’s timeline when I view video source. On my timeline with the error, the video source displays a .M3U8 file format.

Any help is appreciated.
