Title:
Regression in html5 video support in FF 10 & 11
Status in “firefox” package in Ubuntu:
Incomplete
Bug description:
I have observed a regression in HTML5 video support in Firefox 10 and
11. With Firefox 9, HTML5 videos encoded in either Theora or webm
played flawlessly. With Firefox 10 and 11, the video component will
randomly stop playing, while the audio component will continue. This
occurs no matter if I'm watching the video in a window or fullscreen.
I've observed this on locally-produced HTML pages as well as the HTML5
test videos on the Kaltura site. Note that my audio is being routed
through jack, which might explain why the audio continues playing
while the video stops. Firefox itself does not become unresponsive,
however the HTML5 component does.
This is a severe regression for me and makes it impossible to embed
HTML5 videos in the HTML presentations I produce.
What I expect to happen: HTML5 videos encoded in Ogg Theora/webm to
play flawlessly
What actually happens: HTML5 videos encoded in Ogg Theora/webm
randomly stop playing
