Bug 38489 – iPad/iPhone: Video with <source> element(s) does not work on refresh if poster attribute is present

• Status: RESOLVED
• Resolution: FIXED
• Component: Media

This affects the iPad and to a lesser extent, the iPhone. It was possibly introduced in iPhone OS 3.0.

If you have a video element using the poster attribute, and that video element uses <source> element(s) instead of the src attribute, then the play button will fail to appear when you refresh the page and every refresh there after.

To test, view the provided URL on iPad and refresh the page. You can no longer play the video. Refreshing again doesn’t rectify the problem.

Removing the poster attribute on the video element resolves this problem.

The test case provided does not affect the iPhone, but the iPhone does exhibit the behaviour in other test cases (for example, the video on http://camendesign.com/code/video_for_everybody )

Kroc, thank you for reporting this bug.  At this time, please use <https://bugreport.apple.com/> to report WebKit bugs in Safari for iPhone/iPad unless the bug also affects Desktop Safari the same way.  If you don't have an ADC membership, you may create a free "online" account through <https://connect.apple.com/>.

I'm closing this bug as RESOLVED/INVALID since we will continue tracking the bug using Apple's internal bug tracker (Radar), which is also what bugreport.apple.com uses.

Thank you! If I e-mailed you with my ADC e-mail address (which is private), would you be willing to add me to the CC-list for the Radr bug so that I can know when it is fixed?

This has been fixed in iOS 4.0.

And lo, there was much rejoicing.

Now to just wait a year until iOS3 has faded away before I can use poster images on videos again. Yay for Apple and their single-browser view of the web.
