Edge cases related to firing start and stop events

Open youennf opened this issue 5 years ago • 5 comments

Chrome and Firefox do not seem to agree on edge cases related to firing start and stop events when synchronous calls are made. See for instance https://jsfiddle.net/ukqwrvL3/ or https://jsfiddle.net/1kxtpefw/. From my reading of the spec, it seems that on both fiddle, the start event should be fired, even if the recorder was stopped.

Uploaded WPT tests that align with my understanding of the spec at https://github.com/web-platform-tests/wpt/pull/26006/files.

These match my understanding of the spec too.

On https://bugs.webkit.org/attachment.cgi?id=410620&action=diff#a/LayoutTests/imported/w3c/web-platform-tests/mediacapture-record/MediaRecorder-stop-expected.txt_sec1: NB that WPT MediaRecorder-stop.html is wrong regarding throwing in stop().

See https://bugzilla.mozilla.org/show_bug.cgi?id=1669444, where I intend to fix this.

since webkit and gecko agrees on a common interpretation of the spec, is any spec work needed here?
