Additional data points;

1. If I go to the website this video is from http://www.nimportequi.com/ and watch the original "VIDEO STAR DECATHLON - PEKIN 2008" which plays with flash player 9 under firefox 3.0.1 there are no stripes in the video at all.

2. If I play the same file on a Windows XP SP2 machine (via samba) with Media Player 10 there are no stripes in the video at all.

3. Similar artefacts, smaller height and more of (12 rows of), observed in playback of mpeg-2 streams captured from the hauppage video capture card in this machine (520x576).

Original file is 320x240 and appers to have 2 rows of artefacts.


Conclusion, the artefacts are not a result of the conversion from flash to windows media 9 format so the file is ok, it is not a problem with playback of the windows media 9 format as similar issue present in mpeg-2 format playback, flash player appears to use a different video playback mechanism to totem not triggering the problem.

I think on your card the texture adaptor is the default, can you try playing the vid with mplayer and compare the texture adaptor with the blitter and see if the problem remains?(mplayer allows you to specify ports/adaptors, read the man page, use xvinfo to see which adaptors are available, and what is their base port).

Danny, 

nouveau driver version has now cnaged, ROAF pushed an update.

I stopped vmware from starting on boot.

xvinfo reports I have 

  Adaptor #0: "NV40 texture adapter"
    number of ports: 32
    port base: 128

  Adaptor #1: "NV40 high quality adapter"
    number of ports: 32
    port base: 160

  Adaptor #2: "NV Video Blitter"
    number of ports: 16
    port base: 192

mplayer Home-made-olympics.wmv -vo xv:port={128, 160, 192}

All result in the same artifacts in the video.

Even with the collision entry and the RAMHT space exhausted video continues to play, will attach updated dmesg, /var/log/Xorg.0.log and /var/log/messages

That's interesting. Since it happens even with the blitter, and doesn't happen with flashplayer I wonder if this is not a bug in mplayer (or some other component on your system) instead. Do you have the problem with nv or the binary nvidia driver?

I never saw those drm errors before, maybe someone else can comment on that, and whether or not it can be related. 

danny

When using nv no artifacts in video, will attach Xorg.0.log from nv usage

Created attachment 18914 [details]
Xorg log using the nv driver

so the collision message is 100% related to the video artifacts?

You need to load the drm with debug enabled to see what kind of collisions happen and why. But I am not sure it is necessary. Perhaps somebody who understands that gpu object creating code can offer some insight:)

havent done the drm debug=1 thing as yet, but note that the same behaviour persists in ubuntu 8.10

Have upgraded to Ubuntu 9.10 and tried the Nvidia 185 binary driver, the Nvidia driver displays the same stripes I see with nouveau, closing as nouveau is RE´ed from the binary driver so nouveau is not going to be able to fix.   May also be a hardware issue ..... closing
