733293 - High-resolution WebM video on YouTube stutters

Status: NEW

(Core :: Audio/Video: Playback, defect)

Description

[Jesse Ruderman]

1. Ensure Flash is disabled or http://www.youtube.com/html5 is enabled.
2. http://www.youtube.com/watch?v=FG0fTKAqZ5g
3. Turn off the lights.
4. Full-screen.
5. 1080p.

Result: Video stutters every few seconds.

Worse in my main profile, but happens in a new profile as well. Playback is almost smooth in Google Chrome.

Doesn't seem to be due to GC/CC.

This is a fairly new MacBook Pro. The screen is 1680x1050.

We currently don't actively prevent the browser from doing stuff in background during video.
