https://www.w3.org/Bugs/Public/show_bug.cgi?id=24874 Bug ID: 24874 Summary: Positive isTypeSupported() may be misleading (MSE vs. .src=) Product: HTML WG Version: unspecified Hardware: All OS: All Status: NEW Severity: normal Priority: P3 Component: Encrypted Media Extensions Assignee: adrianba@microsoft.com Reporter: ddorwin@google.com QA Contact: public-html-bugzilla@w3.org CC: mike@w3.org, public-html-media@w3.org For a variety of technical reasons, there are likely to be implementations that only support EME with MSE and not with normal .src= URLs. Since HTMLMediaElement.canPlayType(), MediaSource.isTypeSupported() and MediaKeys.isTypeSupported() are all independent, there is currently no way to indicate that the key system or content type can be used with MSE but not normal .src= URLs (or vice versa). Options: 1) Ignore this issue, assuming EME will be primarily used with MSE. 2) Provide guidance, such as the result should be positive if any type of source supports the specified parameters. In practice, a positive response would likely mean one of the following: * EME is supported with both MSE and normal .src= URLs. * EME is only supported with MSE * EME is supported with .src= but MSE is not supported [for the type(s)]. - The latter can be verified by checking MediaKeys and MediaSource.isTypeSupported(). 3) Add a new srcType parameter to MediaKeys.isTypeSupported() that accepts “mse” or “src”. (See issue 24873 for other possible changes to this method.) -- You are receiving this mail because: You are on the CC list for the bug.
