Some h264 movies play back slowly (but not all)

[Scott Ritchie]

I have two movie files of the same resolution and length, both encoded with h264 and ac3 audio, and both of about the same file size. Both worked on Intrepid, but now one of them plays back really slowly.

This is in Jaunty, but both movies worked fast in Intrepid. Installing ubuntu-restricted-extras didn't change anything.

Running them with gst-launch gave the same slowness, so it's not a media player issue

Proprietary nvidia drivers are installed, and my video card is a GeForce 8600M GS

Hi scottritchie,

Please attach the output of `lspci -vvnn`, and attach your /var/log/Xorg.0.log (and maybe Xorg.0.log.old) file from after reproducing this issue. If you've made any customizations to your /etc/X11/xorg.conf please attach that as well.

There that should satisfy you

[Scott Ritchie (scottritchie)]

Hmm, it's possible I was using medibuntu on Intrepid, which as I understand has some patented ffmpeg h264 stuff that may have been speeding it up.

Unfortuantely, the new update did NOT correct the issue, even though the changelog noted some h264 improvements.

[Scott Ritchie (scottritchie)]

Actually, I can't be completely sure. With medibuntu enabled, and using totem, the movies are still slow, but using mplayer, they're fast again. This might be the state things were in Intrepid that I'm misremembering.

I've posted a new version of the -nvidia driver to our xorg-edgers PPA,
would you mind testing it either on Jaunty or Karmic and see if it
resolves this bug?

Get nvidia-graphics-drivers-180 - 185.18.14 here:

[Scott Ritchie (scottritchie)]

The "slow" movie seems to crash outright when opened in current karmic, I'll try the PPA and see if that helps any.

[Scott Ritchie (scottritchie)]

Bryce, I don't see -nvidia drivers for karmic at the PPA, only -nv and -noveau. Was there one I was supposed to install?

Sorry, we ran out of space in the PPA so dropped them because they're
now available in Karmic proper. (Although, you will probably need to
run the .30 kernel since I hear .31 breaks -nvidia currently.)
Anyway, debs can be gotten from packages.ubuntu.com if you don't want to
do a full update.

The latest video drivers in Karmic have made the movie in question playable, and at fast speeds as well.

I've run into a separate bug, however - all the colors are blue tinted in any video.

[Robert Hooker (sarvatt)]

Do you have a seperate bug for the blue colors? I know what the problem is. The Xv saturation ranges have changed and nvidia-settings isn't adjusting it on upgrade. You can lower the slider below 0, then save, then raise the slider back to 0 and save again to fix that.

[Scott Ritchie (scottritchie)]

No separate bug yet Robert, I'm not sure if it occurs on a fresh install of karmic

[Scott Ritchie (scottritchie)]

Robert: Actually it was Hue that I had to set from -1000 to 0

[Scott Ritchie (scottritchie)]

I have confired the hue bug is still a problem and filed it here: https://bugs.edge.launchpad.net/ubuntu/+source/nvidia-settings/+bug/415876

Thanks Robert for pointing me in the right direction.
