The test does some XHR requests to get a video file that just shows a static blue rectangle, but after the revision in question, the expected blue square is not visible anymore. 1825082 1 447456 pnormand 2021-12-17 07:51:18 -0800 Created attachment 447456 Patch 1826226 2 ews-feeder 2021-12-22 00:46:01 -0800 Committed r287349 (245491@main): <https://commits.webkit.org/245491@main> All reviewed patches have been landed.

The video is visible now, there is a blue square as expected but the actual blue square is the color #0100ff and what the test wants is #0000ff. So close. 1826361 5 pnormand 2021-12-22 11:34:09 -0800 It was passing when I submitted the patch but I haven't checked since then. Maybe some of the recent changes around colorspace handling broke it again. Please open a new bug or rebaseline accordingly :) 1826368 6 pnormand 2021-12-22 12:02:16 -0800 Reverting r287323 gets me a blu^Wgreen test again, fwiw. Maybe this should be flagged as a fuzzy test. 1944197 7 aboya 2023-03-27 06:14:39 -0700 r260879 (2023-02-27) was the last build in the bots where this passed in GTK. It has been failing in Release since, while mostly passing in Debug. 1944199 8 aboya 2023-03-27 06:20:32 -0700 (In reply to Alicia Boya García from comment #7) > r260879 (2023-02-27) was the last build in the bots where this passed in > GTK. It has been failing in Release since, while mostly passing in Debug. Wrong revision due to repo changes... Anyway. I've noticed this is a problem with more tests. It seems that the test runner fails to capture video image in the GStreamer ports: imported/w3c/web-platform-tests/media-source/mediasource-video-is-visible.html media/media-source/media-source-video-renders.html media/track/track-webvtt-no-snap-to-lines-overlap.html media/track/track-webvtt-snap-to-lines-inline-style.html media/track/track-webvtt-snap-to-lines-left-right.html media/video-with-alpha.html 1944201 9 philn 2023-03-27 06:23:15 -0700 That's https://bugs.webkit.org/show_bug.cgi?id=244727 2179867 10 csaavedra 2026-02-10 08:23:13 -0800 Someone more familiar with this should check this, but I noticed that most of the tests gardened under this bug are actually passing most of the times, with very rarely a timeout and no image failures.
