patchCanPlayType is called on load.
It patched video#canPlayType if needed.
unpatchCanPlayType will revert the patch and return the patch function.
There are also corresponding tests that test patchCanPlayType,
unpatchCanPlayType and also whether the patch functions themselves work
correctly.
Android devices starting with 4.0 can play HLS natively to some extent.
However, they do not say so in the canPlayType method. This commit
monkey patches canPlayType to respond with "maybe" for
"application/x-mpegURL" and "application/vnd.apple.mpegURL". Otherwise,
it'll fallback to the original canPlayType method.
When poster() is called with a URL, fire a `posterchange` event to update the PosterImage source and update the video element attribute.
Trigger posterchange after updating the tech
Wait until the tech has updated its poster image before alerting components so they don't see the intermediate state in event handlers. Remove unused variable from PosterImage.createEl.
Don't create new img elements each time the poster is set on ie8
Create the img fallback for the poster during PosterImage initialization on ie8 so we can avoid having to check and possibly create it each time the src is set. Add a test to ensure that new elements are not appended to the poster component when the img fallback is in use and the src attribute is modified.
fixing a broken IE8 test, and adding a negative test, for poster switching.
modified the poster-switching test to accomodate IE8
added a negative test for an undefined poster
fixed the assertion message in the 'undefined' image case
fixed test breakage in Firefox and IE10 (quotes were not being handled properly in the test data)
testing:
ran the tests at the command line, and in Chrome, Firefox, IE8, IE10, Firefox and Safari
all passed
