I'm creating a meta bug for the multimedia failures, because I'm not familiar with multimedia to investigate every failure and report individual bugs. Feel free to file separate bugs blocking this one. Regressions: Unexpected timeouts http/tests/media/track-in-band-hls-metadata-crash.html [ Timeout ] media/media-fullscreen-loop-inline.html [ Timeout ] media/media-source/media-source-error-crash.html [ Timeout ] media/media-source/only-bcp47-language-tags-accepted-as-valid.html [ Timeout ] media/video-multiple-concurrent-playback.html [ Timeout ] Regressions: Unexpected text-only failures fast/mediastream/MediaStream-MediaElement-setObject-null.html [ Failure ] fast/mediastream/RTCPeerConnection-more-media-to-negotiate.html [ Failure ] fullscreen/video-controls-rtl.html [ Failure ] imported/w3c/web-platform-tests/html/semantics/embedded-content/media-elements/readyState_during_canplaythrough.html [ Failure ] media/media-preload-no-delay-loadevent.html [ Failure ] media/track/track-datacue.html [ Failure ] media/video-background-playback.html [ Failure ] media/video-concurrent-playback.html [ Failure ]
Note that all of the above are recent regressions, within the past few months. I remember filing individual bugs against all failing multimedia tests not so long ago, maybe October or thereabouts.
Update at r218320 media/video-multiple-concurrent-playback.html is [Failure Crash] media/video-seek-past-end-paused.html is [Failure Pass]
(In reply to Carlos Garcia Campos from comment #0) > fullscreen/video-controls-rtl.html [ Failure ] This one's checking pretty specific properties of the mediaControlsApple.js code.
media/video-seek-past-end-paused.html has not failed since around r222638, being affected by 198830 instead.
media/media-source/only-bcp47-language-tags-accepted-as-valid.html times out might be related with this: CONSOLE MESSAGE: TypeError: undefined is not an object (evaluating 'audioTrack.language = validLanguageTags[i]')
