Video playback is broken on both Ubuntu Karmic and Lucid, unbearably choppy visuals and sound

GoogleCodeExporter commented 9 years ago

What steps will reproduce the problem?

I have the latest Ubuntu Lucid Lynx desktop on a Dell 1525, but have also
tested previously on a Lenovo T400 with Karmic with the same results. One
common factor could be an Intel video chipset.

1. Launch the video example program like...
python video.py tada.avi 
...using the tada.avi test video distributed with Bruce the presentation tool.

2. Observe frame refresh rates of maybe one every 5 seconds, and sound
broken up into 200ms chunks with 1000ms spaces in between. There are no
errors logged to the console.

3. Try installing newer avbin, newer ffmpeg, newer pyglet, newer Intel xorg
drivers (2.11). None of these have any impact

I am also having this problem

I just retested this with my current build and I find that the glitches have 
gone, at least for tada.avi video I was testing it on before. It's the same 
laptop, so something must have gone right.

It still has difficulty playing big buck bunny at full res ogg, but that might 
be the player library.

I'm running a fairly vanilla Lucid Lynx plus various packages updated from the 
Ubuntu 'proposed' repository in Synaptic including a newer kernel, compiz 
libraries and flgrx-modaliases
