HTML5 Conformance Test failure: approved/video/video_003.htm

• Component: Media
• Status: RESOLVED WORKSFORME

The approved/video/video_003.htm test fails with WebKit nightly build r70732 run in Safari 5.0.x.

@abarth: Does browser mime type sniffing behavior come into play here?  Just wondering if the test is expecting the application/octet-stream MIME type to be sniffed, or whether it's testing whether the browser will dump off bytes to the "media engine" with a MIME type of application/octet-stream.

Video media type handling is a train wreck.  It's unclear what the best behavior is.

http://test.w3.org/html/tests/approved/video/video_003.htm is a bogus test. The spec says:

    The canPlayType(type) method must return the empty string if type is a type that 
    the user agent knows it cannot render or is the type "application/octet-stream"

In other words if MUST return "" if the type is "application/octet-stream". The test, however, *fails* if it returns "" :

    if (vid.canPlayType("application/octet-stream") != "")
    {
        passTest();
    }

WebKit returns "" for "application/octet-stream":

> vid.canPlayType("application/octet-stream")
   ""

If there's a bug in the test, this should be reported against the test suite.

[David Kilzer (:ddkilzer)]

This test has been removed from the test suite.
