Bug#748798: totem: 100% CPU usage during ten seconds after opening a video file

[Jérémy Lal]

Package: totem
Version: 3.12.1-1
Severity: normal

Hi,

on several video files (typically, x264-encoded with mp4 container),
during the first seconds after starting playing the file:

* CPU is > 100% on process totem
* movie is choppy

This happens independently of current time position, and
independently of window size.
It doesn't happen (at all) with gst123 or gst-play-1.0.

After that, totem CPU usage is around 30% and a little choppy,
while gst123 CPU usage is around 20% and smooth.

Downgrading gstreamer to 1.2 didn't change the situation, nor
disabling all plugins.

Jérémy.
