Sound but no video
I am using the cloud-hosted version jw player.
I created this page: http://bodyandmindsynergy.com/personaltraining/jwtest/
I see the video flash on the screen briefly then disappear and only hear sound.
I used handbrake to create an mp4 file that I uploaded to amazon s3.
In wordpress backend when creating the page, I clicked on add external media, used the amazon url for the video, chose the player, saved/updated.
Any ideas what's missing here?
