183214 2018-02-28 09:45:27 -0800 [GTK] compositing/video/poster.html: video bar inconsistently filled after 'canplaythrough' 2023-01-10 07:43:02 -0800 1 1 1 Unclassified WebKit WebKitGTK WebKit Nightly Build Unspecified Unspecified RESOLVED FIXED P2 Normal --- 1 aboya webkit-unassigned bugs-noreply oldest_to_newest 1402636 0 aboya 2018-02-28 09:45:27 -0800 The following test has a ImageOnlyFailure flake: compositing/video/poster.html https://build.webkit.org/results/GTK%20Linux%2064-bit%20Release%20(Tests)/r229090%20(5649)/compositing/video/poster-diffs.html It contains this code: <video controls id="v" poster="../resources/simple_image.png"></video> <script> var v = document.getElementById("v"); if (window.testRunner) { testRunner.waitUntilDone(); v.addEventListener("canplaythrough", function() { testRunner.notifyDone(); }); } v.setAttribute("src", findMediaFile("video", "../resources/video")); </script> The video poster looks perfectly fine, the problem is with the controls; particularly the bar. notifyDone() is called after the "canplaythrough" event. At that point, enough video should be buffered for smooth playback, but most of the time when the screenshot is taken the bar is still empty. 1924421 1 dpino 2023-01-10 07:42:56 -0800 The test or tests filed under this bug are not failing anymore.
