Description Cesko Voeten 2009-08-10 08:28:31 UTC 
Note: I reported this bug against Totem, but ALL other media players I tried (VLC and Mplayer) have the same problem. I do not know which common component is causing the issues, therefore I chose to report it against the player (Totem) itself. I apologize if I did this in error.

Description of problem:
Playing any video file causes the player process to consume around 80% cpu (around 150% according to top). (3ghz dual core intel processor).
Audio-only files play fine.

The videocard I'm using is an Intel 865g, and I'm using KMS. (Not sure whether this is relevant - unfortunately X crashes whenever I try to log in with KMS disabled, so I can't check whether KMS is causing this)

Version-Release number of selected component (if applicable):
totem: 2.26.3
xorg-x11-drv-intel (not sure whether relevant): 2.7.0-7.fc11

uname -a output:
Linux [removed computer name] 2.6.29.6-217.2.3.fc11.i686.PAE #1 SMP Wed Jul 29 16:05:22 EDT 2009 i686 i686 i386 GNU/Linux

How reproducible:
Always.

Steps to Reproduce:
1.launch the 'top' program in a terminal (so that you can observe the CPU usage)
2.play a video file in any media player
3.observe the CPU usage of the player process rise to an extremely high level
  
Actual results:
CPU usage is very high, video plays choppy

Expected results:
CPU usage is 'reasonable' (on Windows, using VLC, the CPU usage never goes above ~10%)

Additional info:
Videocard: intel 865G
KMS enabled
Tried various configurations of affected programs (VLC/Totem/Mplayer) to no avail

My guess is that there's no Xv acceleration on your system.

What's the output of "xvinfo" on your system? Is it only certain file types or a certain file that causes problems?
Comment 2 Cesko Voeten 2009-10-06 13:56:24 UTC 
xvinfo output:

X-Video Extension version 2.2
screen #0
 no adaptors present

(strange.... is this a driver issue?)

I tried a few files (mostly avi but also mpg and wmv), and they were all affected.
Comment 3 Bastien Nocera 2009-10-06 16:39:38 UTC 
This is definitely a driver issue, or a configuration issue. Your video is completely unaccelerated.

Attach /var/log/Xorg.0.log and /etc/X11/xorg.conf to this bug.

FYI, this is what it looks like on a working card:

X-Video Extension version 2.2
screen #0
  Adaptor #0: "Intel(R) Textured Video"
    number of ports: 16
    port base: 71
    operations supported: PutImage 
    supported visuals:
      depth 24, visualID 0x21
[...]

xorg.conf didn't exist (sorry for not mentioning this in my previous comment, I *thought* I had mentioned it in that comment but I now see I didn't)
