810144 - Firefox frozen (or very slow) while accessing a 22MB OGV video

Status: RESOLVED WORKSFORME

(Core :: Audio/Video, defect)

Description

[Oliver Hessling]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:16.0) Gecko/20100101 Firefox/16.0
Build ID: 20121025212310

Steps to reproduce:

while browsing on Wikipedia, I opened this URL:
http://upload.wikimedia.org/wikipedia/commons/e/e2/Animation_of_the_planetary_system_around_Sun-like_star_HD_10180.ogv


Actual results:

Firefox was like frozen. When clicking on another tab, Firefox responded more than 5 or 10 seconds after. I have i7 Ivy-Bridge + 8 Go RAM + SSD and just running Firefox using about 6 tabs.


Expected results:

Firefox should buffer the beginning of the OGV file without freezing.

After rebooting twice the browser and restoring the previous tabs, I spent some time on my GMail tab. I also disabled NoScript addon. After about 5 minutes, I went back to the OGV tab, and the firefox played correctly the video.

However, I press the download button and this download started only when I closed the OGV tab.
To download the video I did on my French menu:
Outils -> Informations sur la page -> Médias -> Enregistrer sous...

I try to guess the English version:
Tools -> Information on the page -> Medias -> Save as...

Bad things to improve:
 1. the OGV file was not on cache
 2. the save as did not reused the playing OGV file, but re-downloaded it again
 3. the OGV download should start immediately and should not wait for tab close

Cheers
Oliver
