782817 - Sometimes (e.g on BMO) Firefox autoplays finite length audio/video files like infinite length audio/video streams (the seek bar stays stuck at the end of the duration)

Status: RESOLVED DUPLICATE of bug 575459

(Core :: Audio/Video, defect)

Description

[Loic]

You can test the issue easily on BMO.
Open a finite length audio (https://bugzilla.mozilla.org/attachment.cgi?id=461797) or video (https://bugzilla.mozilla.org/attachment.cgi?id=643908) file in Firefox.

Result:
Firefox autoplays the file but the seek bar stays stuck at the end of the duration.
If you click on the play button a 2nd time when autoplay is over, the seek bar moves normally from the left to the right.

Autoplaying finite length files behaves like playing infinite length streams (like http://audio-ogg.ibiblio.org:8000/wcpe.ogg).

So it's a dupe of bug 575459, no?

Yeah.
