751080 - --enable-gstreamer claims WebM and H.264 videos are corrupt on Ubuntu 12.04

Status: RESOLVED WORKSFORME

(Core :: Audio/Video, defect)

Description

[Henri Sivonen (:hsivonen)]

Steps to reproduce:
 1) build Firefox with --enable-gstreamer on Ubuntu 12.04 
 2) view some WebM or H264 video that's embedded using the video element using the browser-provided controls e.g. http://hsivonen.iki.fi/hourglass/ and http://hsivonen.iki.fi/test/moz/video-selection/src-mp4.html

Actual results:
The video element draws text that claims that the video file is corrupt even though the file plays in Totem. Theora videos play OK.

Expected results:
Expected WebM videos to always play.  Expected H.264 videos to play if Totem is able to play them.

Additional info:
Things were OK under Ubuntu 11.10.

No idea what happened, but this started working (without rebuilding Firefox).
