Bug ID: 432303 Summary: Knocking on rooms at whereby.com fails: DOMException: The fetching process for the media resource was aborted by the user agent at the user's request. Product: plasma-browser-integration Version: unspecified Platform: Fedora RPMs OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: Firefox Assignee: k...@privat.broulik.de Reporter: devuran...@gmx.net Target Milestone: --- SUMMARY When knocking on a room in Whereby, when I press the "Knock" button, I see the message "Unable to start camera to take picture" in the preview that shows my live camera feed. Instead it should progress to the waiting screen. STEPS TO REPRODUCE 1. Install "Plasma browser integration" add-on into Firefox 2. Try to join a Whereby room that is locked - See the "This room is locked" screen, as usual. - The camera is active and you can see yourself in the preview in Whereby, as usual. 3. Press the "Knock" button OBSERVED RESULT I see the message "Unable to start camera to take picture" in the preview that still shows my live camera feed. In the browser console I see the error `DOMException: The fetching process for the media resource was aborted by the user agent at the user's request.` EXPECTED RESULT Whereby progresses to the usual waiting screen and the "Knock" button turns into "Cancel". WORKAROUND 1. Browse to a knock screen on whereby.com 2. Click the "Plasma browser integration" icon in the add-on icon bar 3. Untick "whereby.com" in "Enable media controls on" Whereby support is aware of this workaround and in fact suggested it to me based on experience of other users who encountered the problem before me.
