• Status: RESOLVED
• Resolution: INVALID
• Component: WebKitGTK

imported/w3c/web-platform-tests/media-source/mediasource-changetype-play.html [ Crash ]
media/media-source/media-source-canplaythrough.html [ Crash ]

STDERR shows this: g_object_ref: assertion 'object->ref_count > 0' failed

The backtraces are pretty similar but not exactly the same:

[Miguel Gomez]

Forgot to mention that it's not clear when the first one started failing, but the second one happened between r253325 and r253360

[Diego Pino]

r253372 changed test expectations for imported/w3c/web-platform-tests/media-source/mediasource-changetype-play.html to [ Crash Pass ], but besides Crash the test has also been reporting Failure since then. I'll update TestExpectations.

[Diego Pino]

media/media-source/media-source-canplaythrough.html has been consistently passing, without a single crash, for the last 4000 revisions (at least r257291). Removing from test expectations.

[Diego Pino]

Closing this bugs as these two tests are no longer passing.

media/media-source/media-source-canplaythrough.html was already removed from TestExpectations as the test is passing.
