942450 - MP4 playback broken in Firefox 28: only audio, no video or controls

Status: RESOLVED DUPLICATE of bug 937429

(Core :: Audio/Video, defect)

Description

[Loic]

Attachment: leopard-seal-eats-penguin.mp4

STR:
Open http://pecheur.info/leopard-de-mer-mange-pingouin.html and read the MP4 video at the end of the article.

Result: the video starts and after a few seconds, the playback goes back to the start and stops.

The behavior is different with the direct link of the MP4 video:
http://pecheur.info/video/leopard-seal-eats-penguin.mp4

Firefox 25: the playback works normally but the seekbar goes directly to the end instead of beginning normally from the start. It's possible to go back with the seekbar anyway.

Firefox 28: only audio, no video or controls. Broken playback.

Regression range for FF28:
good=2013-11-07
bad=2013-11-08
http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=70de5e24d79b&tochange=f003c386c77a

I think there are 2 bugs: the seekbar broken in FF25 and one more in FF28 with the playback broken.
