    Exclamation ZA and VLC Media player

    Since updating ZA ISS, either the most recent update or the one before that possibly, I've noticed 2/3 of the time if I watch something in VLC media player it stutters very slightly, the jumping enough to be a nuisance, and of all things, shutting down ZA without even closing the media player cures it. ZA occupies some processor time, anywhere between 5-15%. The file is local, so I don't see why ZA should want to scan the file as it's read.

    Has anyone else seen this behaviour?

    Sorry, sure. I forgot I had two posts on the go and posted some version info in the other.

    ZA currently 9.3.013.000
    VLC 1.0.5 "Goldeneye"
    AMD Phenom 2 3Ghz, 4GB RAM (3.2 usable obviously)
    XP Pro SP3 (32-bit)
    HDDs totalling > 1TB, about 40% used.

    CPU activity around 15% while watching. Viewing the same media in WMP CPU usage is about the same, but WMP does not manifest the problem.

    Investigating further, it seems to be related to internet activity; as activity increases, so does the interference.
    e.g. browsing through a Google image results page causes repeats of what seem like 100-300ms in length (you can hear entire words repeated)
    Files are local and it doesn't seem to matter what type, size, etc.

    If I "Stop all internet activity" on the context menu, the problem goes away even though CPU usage only drops a litte. I can do other things to push CPU activity to 60-70% and the problem still isn't manifest, if internet is disabled.

    Weird?

    So what is the media you trying to view? If its media that HD then that could be an issue since HD streams and data puts a huge weight on the PC's resources and sometimes simple things like browsing will make the video player skip or glitch when playing HD type of content. In this case there nothing that can be done.

    Can you give an example of the content the has issues for you?

    I haven't tried HD content, but the media doesn't seem to matter. Most vids are XVID, 624x352, audio mpga 48K 32kb/s. Same happens with mp3 and mp4 audio tracks, CD audio, DVDs and streamed audio. None of the above have problems in WMP.

    Well VLC's performance on the PC will vary greatly depending on the source video and audio and how it was encoded.

    I tried several source formats and encodings and I get anything from 95-99% utilization for some formates to as low as 20% but with all the video I played anytime I opened IE and loaded msnbc.com there was different levels of video/audio stuttering. I also observed huge spikes in resource usage from IE.

    This subject keeps coming up in the forum and the resource drain on a XP or even low powered Win 7 system can be huge when your trying to watch video or audio.

    There is really nothing that can be done besides not trying to multitask video and surfing or finding a source format that uses less CPU cycles on your particular PC.

    You may want to join one or more of the many good video forums out there. VLC probably has a user forum also.

    Users there are so much more technical in video and can give more explanations.
