problem with playback of large video files

Lancelot1 · 02-22-2009, 07:52 PM

I have an issue with playing back large video files -- larger then 5gb mkv files. The issue is with video running slow and sometimes just playing black screen while audio keeps on.

How to fix this? Is this a X11 issue? I'm running Ubuntu 8.04 LTS with NVIDIA graphics card (6 series).

I tried playing this file with serveral players all had the same lagging video effect. The video was on my HD.

So the same media players will playback smaller video files with no issue? Can you copy the file to another box--even Winderz--to ensure the file itself isn't corrupted?

problem is maybe corrupt file. I had another 8GB file which played back fine. But that file was 720p while the file that won't play back all right is 1080p

my sys is:

AMD Athlon 64 X2 Dual Core 4450e
2048 MB mem
nVidia GeForce 6150 SE GPU
128 MB dedicated mem max 831 MB

and I used Vlc, Mplayer, xine, dragon player etc etc

From what I can see I'm using the latest nvidia propriaty drivers for my video drive

"latest nvidia propriaty drivers for my video drive"
so you installed the nvidia.run installer from the nvidia web site .
that file may be 1080 but what format ( vob,avi,mpg,mp4,rm ?)
if it is a "real" format then install quicktime

like I posted it's a mkv with v-mp4/iso/acv codec which I also have in the playable file. So i'm guessing no codec issue or player issue.
But what I'm think might be an issue other then corrupt file is the X-server buffering/caching. Is it slow because of that or can't that be an issue?

btw some extra info when playing in Mplayer after about a minute I get a buffer error: too many packets in the buffer
