Same for me except I only have 1GB RAM, it seems to happen less if i quit other open applications, it's also more of a problem in 0.8.4 (beta's and release) than 0.8.2 but it still exists. It happens on different .avi's all stored locally. They play fine on Mplayer, but in full screen that seems to have the menu stuck at the top... (and they don't play in Quicktime... I think they're X-vid but I cannot confirm...)I have the same problem on a iMac G5 2.0Ghz with 1.5GB RAM.No, this is occurring with AVI files.
The video plays normally, no distortion, but will freeze up for a second or 2 then play normally again and it happens every 30 seconds to a minute.
I have tried it with multiple files from multiple sources to make sure it's not the files that are the problem.
Sometimes the avi files run just normal (all the files are stored on the local HDD), but very often I have those 1-3sec freezes during playback. In worst cases the movie freezes like every other minute.
Is there any way to prevent that behavior of vlc, or is it a known bug that maybe will be fixed in an upcoming release?
Any tips/help would be musch appreciated!!
I concur. with previous versions of vlc i could watch dvd video just fine on my 800mhz g4 ibook. now i get quite a bit of stuttering and green or garbage blocks in the video output. anyone know what change may be causing this? has something made video decoding much more computationally intensive in the 0.8.4 build, or is this a buffer size issue of some sort? i have tried adjusting several of the settings with no perceptable effect on this behavior.as of version 0.8.4 vlc has become much slower than before. now i'm experiencing much the same stuttering playback as described in this thread. my computer is a powermac g4/400 but so far it seems it has been able to cope with everything i throw at it.
most of the stuttering seems to be due to missed keyframes - the image freezes or turns into smudge - during which the audio is playing without trouble - until the next keyframe is properly decoded. i also experience regular stuttering playback during panning and fast motion.
now on to the strange things... i decided to revert to version 0.8.1 which i find for me to be the best working version so far. but something must have changed within the settings because now i'm starting to experience the dropped keyframes in 0.8.1 as well, though only about every 5 minutes or so (unless dimensions are really high like 720px or so). otherwise the video plays as good as before.
I have been experiencing the same thing on my iMac G5 2 GHz.I encounter this problem too, quite regularly. When playing .avi files, the movie will freeze for a moment every couple minutes, then pick up a few seconds later. There is no audio or video during the freeze, then they pick up fine afterwards. Rewinding to that point and playing again doesn't experience the same problem.
The key thing I've found is that I get the error consistently while playing files from my internal (Serial ATA) drive, but never when playing from my external (ATA by Firewire) drive. My computer is a dual 2.0GHz desktop with 2.5GB RAM, lots of drive space and not much else running when the problems occur.
I will try increasing the cache size as someone mentioned. Thanks for the tip.
First, I never meet problems described before when playing movie from local hard drive.Well, the problem is that we can reproduce this behaviour neither on my iMac G5 (2 GHz) nor on our PowerMac G5 (Dual 1.8 GHz).
My usual response to any problems is the recommendation to delete VLC's preferences files. I'd suggest that here as well, but I doubt that this will help.
I was also experiencing these problems in my 2ghz iMac 2gb RAM with no other programs running. These fixed them, as far as I can tell.one solution i've found which works reliably well.
(check advanced in prefs for these)
prefs->video->output modules->switch from default to quartz (it seems to speed things up.. maybe default tries core video?)
prefs->input/codecs->access modules->files->up caching to 2000 milliseconds (this does not noticeably change response time.)
I have had some success using samba by adding the following [global]'s to smb.conf:Trying to play any form of movie on a network share with VLC is a bad idea. Mac OS X handles the small reads that VLC does very badly. So far only NFS shares have worked for me. You can enlarge VLC's file cache to prevent hickups due to the slow response of the file reading, but this introduces delays in play/pause/stop commands.
I have similar problems -- green blocks, stuttering -- especially with H.264 input, which would cause major stuttering and then a crash. I found a quick fix for dealing with H.264 files: Go to Preferences>Input/Codecs>Demuxers>H264 and lower the "framerate." Mine is set to 16 right now. It doesn't appear to actually lower the frame rate -- the audio plays at a normal rate and the video is much smoother and syncs up fine.
I got the same problem when <b style="color:black;background-color:#99ff99">vlc</b> 0.8.0 was released.
<b style="color:black;background-color:#99ff99">Vlc</b> 0.7.2 plays high definition files (.<b style="color:black;background-color:#a0ffff">ts</b>, 1080i) on my 2x2GHz with around 60% processor usage with interlace blend. With 0.8.0 that almost doubled to 100 - 110%. With 0.8.4 it jumped once more to consume even more resources.
It never lags or drops frames though but I can't for the life in me figure out what happened between 0.7.2 and 0.8.0 that eats up the processors.
I guess I have to run 0.8.4a now if the digital audio is fixed but it's annoying that something that used to take around 60% now requires anything from 100 - 200%.
