choppy video

[laksman]

i have problems watching videos on vlc but when on another player it works fine. so basically this is what happens i get "hiccup"y videos and then it skips through the video. what can i do to make this work? im using the latest version and i reinstalled it 3 times.

1. Update your Audio cards drivers.

2. Update your Video cards drivers.

3. Update DirectX runtime (8/06).

It you still have problems at this point try a different sound card.

I've the latest Sound Card Drivers, Video Card Drivers and DirectX. But i can't point to my sound card/ video card as the Problem. The same file works on Windows Media Player but is messed up on VLC. Well my specs are:

CPU: AMD FX-55 @ 2.6GHz
Motherboard: Asus A8R32-MVP Deluxe [Built in Sound Card]
Video Card: ATI Radeon X850XT Platinum Edition 256MB
RAM: 1Gb

But what could the source of this problem be? I can't think that my video card or sound card is responsible either

I'm having a similar problem, I didn't have it until i upgraded my pc. I've updated all of the driveres you suggested, i tried the other sound card, and still i get the problem. Is there anything else I can do as I'm trying to create an entertainment system and its gonna be rubbish if the video is choppy.

All digital video is follow audio for sync. A few players do not do this. But VLC is a packet based player capable of streaming. The culprit then becomes your audio card. Yes, the video is also possible but less likely these days. Computers do NOT employ the use of PLLs and clocks drift. This also causes issues for some chip sets and or machines.

For reference only, see ReClock on the web.

I have the same problem here since I updated from vlc 0.8.2 to 0.8.5.

I just updated DirectX (08/06) and checked to have the latest audio driver.

I had no issues whatsoever with vlc 0.8.2.

[DJ]

The DirectX module was rebuilt starting with 0.8.4 forcing many people to adhere to Microsoft's recommendations of Oct 04 for DirectX 9c which was to update your audio and video drivers.

This change also pointed out problems with cheep audio cards or chip sets.

i used the reclock thing, same problem. the video skips like from 00:02 to 00:16, and i doubt my chipset is cheap.. 250 dollars man

Doubtful ReClock will work with VLC. It took me several days of playing with it to get it to work. The note was made for reference only and did not suggest for you to try the program. The documentation clearly explains the real problems associated with digital video when used in any computer and this was the reason for the reference.

[laksman]

so is the problem with vlc?

[DJ]

No! The problem is with your hardware. If the problem were VLC everyone using any operating system would be here complaining.

The most general answer by the Devs to your query is "cheep audio cards". But it has been my experience that this happens more for on board chip sets (and then more for some Manufactures than for others) than it does for real audio cards.

[laksman]

well mine is a pretty expensive motherboard which has the built in sound card i can't see how theres a problem

[DJ]

Since when does price denote quality? But as long as you continue to believe this, I guess it will never be fixed.

If you have tried to toggle the float32 option in preferences, audio, output modules, directx and you have tried shutting down directx in preferences, audio, output modules "Win32 waveOut extensions output" and neither work the the problem is the audio card. But if either of these options work the problem is most likely the drivers. Either way the problem is most likely your audio card in some way! Or at very least a timing issue causing clocks not to lock or lock in the wrong place.

I don't know if this may be helpful to you or not but it is worth a look!

[laksman]

but why does the same video work fine in an another player such as WINDOWS MEDIA PLAYER

[DJ]

Because not all players are created equally. They can even use DirectX differently. A DVD for example has no CPU impact in VLC but a Direct Show player may show 25 to 30% CPU usage with the same DVD on the same machine and is still using DirectX. VLC is a packet based player designed to stream media files (not a dshow player) and this is nothing like other players. I have also been asked the question in reverse. IE why does VLC work when dshow doesn't?
