This is (currently) expected behavior. The file in question is encrypted, and the parser is stalled waiting for the page to handle the generated "encrypted" event. I suspect that the stalling WPT tests in question are EME tests, and there is no EME test support for FairPlay encryption, which is the only CDM Cocoa-ports support. |
Created attachment 439627 [details] testcase (but needs file from WPT) Loading the attached test over HTTPS from the web-platform-test server/directory gives: Resource fetch success [object MediaSource]: sourceopen [object SourceBuffer]: updatestart This isn't an acceptable output, as far as I can tell; there should always be an updateend event (and either an update or error event between them). This is causing a fair few WPT tests to timeout in Safari, so this would be good to improve.
