The Curious Case of Quicktime Autoplay in Safari
Ever since I installed Snow Leopard, I’ve been battling with a strange bug in Safari. If I go to a website with several embedded videos, they all start playing simultaneously. I’d been in the head of the page with no video present in the current view when suddenly all the audio streams start playing and overlapping each other. Cue heart attack. Here’s what happens:
I’ve been searching Google, combing the Apple discussion boards with no clue or direction on how to fix this bug. Then this morning I had an idea. I thought it must be a Safari plugin… and it was. I’ve been using a flash blocker called ClickToFlash and it was the culprit. When it intercepts YouTube videos it sets them all to Autoplay and they all start playing. Thankfully, it’s been reported as a bug in the ClickToFlash support board.
Once I removed the plugin from the ~/Library/Internet Plugins folder, Safari behaves normally as seen here:
UPDATE: As I mentioned before, there is a support ticket to fix the autoplay bug in ClickToFlash 1.5fc2 and there is now a workaround as well. In the ClickToFlash Settings window, make sure Load H.264 Videos from YouTube is unchecked.
