totem -stuttering/bad performance with mp4 video

[OCP_001]

Binary package hint: totem

I am experiencing bad video playback performance/stuttering when playing mp4/h264 video files.

It is not a performance problem of my system, because the cpu stays more or less idle during playback. No problem with xvid, avi or other codec types.

Running ubuntu 7.10 on a Core2Duo Mobile System with Intel 945GM.

Thank you for your bug. What is the issue exactly? Does it do the same if you use "gst-launch-0.10 playbin uri=file:///path/to/video"? Could you attach an example to the bug or provide an url to download one?

[OCP_001 (ocp-001)]

Yes, the problem is the same when launching manually.

A good example video can be downloaded (via bittorrent) from this url: http://www.anime-kraze.org/torrent/%5BA-Kraze%5D_Seirei_no_Moribito_-_23_%5B75667171%5D.mkv.torrent
Launch the mkv file and you should encounter stuttering playback/short drops in framerate after 10-15 seconds of playback. When watching carefully (and ignoring the silly soundtrack) you should also see greenish screen glitches to the left border of the playback window (ca. 1:17 playback).

This problem is not limited to this file, I encounter it when playing any file with mp4 codec.

I can confirm this bug.

Im using Ubuntu 7.10 (AMD64) on a Athlon X2 4800+

same symptoms, if I open a video with a h264 Stream, it stutters badly (drops alot of frames) like its been played back at 4-5 FPS. Audio plays back smooth and CPU utilization never goes above 15%. "Older" Mpeg4-Streams (Xvid/h263) dont have this problem.
Disabling compiz has no effect on this, and neither disabling clockthrottling.

the Gstreamer-FFmpeg Plugin v 0.10.3 seems to greatly improve it, must be related to this fix: http://bugzilla.gnome.org/show_bug.cgi?id=342962.
.
But some movies still are jerky.

Thank you for the information. Can someone else confirm if this bug is fixed?

in hardy beta i have similar corruption
video file codec XVID MPEG-4
nvidia 8500gt

This same thing happens with an avi file I have here. Nautilus and Totem say it is a "Microsoft Windows Media 9/MPEG-4 AAC audio" format. The audio is fine, but the video is very bad with green/purple blocky artifacts wherever there's movement on screen. It's the same when I use the gst-launch command you gave.

I've seen this kind of error before, but thought it was a mistake on the encoding end or something (you know, like too much compression in jpeg images). Turns out it is a totem bug after all then :/

The fixed version of gstreamer0.10-ffmpeg has been in Ubuntu for some time.
