Audio and Video skips

Postby DiGiTY » 16 Jul 2007 01:24

I'm running VLC 0.8.6c on a [2nd gen] MacBook (OS X 10.4.9) and when i'm streaming QuickTime files (.MOV with H.264) from my PC the audio goes mute for about 1 to 2 seconds and the video pauses/stalls for the same amount of time then they both start again and i basically miss what was said and displayed for that period. i guess this is called skipping. i also have skipping problems when i'm streaming MP3s and playing them off the hard drive. I'm assuming i'll have the same problem with playing video off the hard drive too given the situation

any ideas why VLC skips and how i could fix this?

The same thing happens to me, but only when I'm connected wirelessly. When I'm plugged in, it's fine.

At first I thought it was just a crappy connection, so I tried the same files (mp3, avi etc located on a Windows server) in different applications (iTunes, Quicktime etc), and they all work fine. VLC is the only app that has a problem.

Is there perhaps some setting within VLC that would fix this?

having the same problem on a full spec macbook pro on 10.4.11.
video/audio will skip every few minutes or so for a period of 1-2 seconds, also when playing files locally.
tried all vlc 0.8.6 versions to no avail, tried the hurry up options in the video preferences as well.
anyone have a solution to this problem yet?

Hi, I have the same problem, with Windows XP (on a P4 2.53Ghz) using a wireless connection to access the video file, and also with Windows XP (Athlon XP 2100+) but playing the video from the harddisk.

I tried to solve it increasing the "Caching value", but with no result.

I am having this issue as well, I have a CentOS server in my closet that i am able to stream media with my xbox and other players but with VLC it skips but it doesn't seem to happen if i transfer files over to the local HDD or if i play from a DVD. I was wondering if there might be anything i could try.
ps love VLC on the mac, have been a user on linux/windows for years but just recently got a macbook

Increasing the priority seems to have worked for me on Mac OS X (10.5.6) with VLC 0.9.8.

In terminal, run the following:

Code: Select all

$ ps A | grep VLC 6028 ?? S< 1:26.62 /Applications/VLC.app/Contents/MacOS/VLC -psn_0_1618315 6107 s004 R+ 0:00.00 grep --color VLC $ sudo renice -n -1 6028
Of course, replace 6028 with the actual PID of VLC (the first number on the line containing "/Applications/VLC.app..."

i'm getting the same error, with the exception that it seems to only be affecting my audio. it will sputter one for a couple minutes or so (the record is 7) and the just crash. I'm new to this old mac and could use some pointers. im using vlc 0.8.4 running on osx 10.2.8 ]
