The VideoLAN Forums

Don't know what happened! Overnight, I was unable to watch any video file with VLC 0.8.6c. I tried with VLC 0.8.6b but it just was the same thing: the sound is great, but there's no video whatsoever and there is no error message either. Nothing. As if I my .avi or .mp(e)g file is a .wav or .mp4 file basically. But of course I know it's not!
Actually, this very problem reminds me of another one, quite similar that occured a few moths ago. I had automatically downloaded the then latest version of QuickTime and I was then unable to watch any video with VLC. And here we go again, obviously. 2 or 3 days ago, I once again downloaded the latest version of QuickTime -I just checked and it's the 7.4.0 (92) version- and at first I did not make any connection between the two, but I guess this is where lies the problem...
Any advice?

Thank you very much.

have you tried deleting the preference file for VLC and trying again.

Well, I'm French and I'm not very acquainted with English so I guess it's going to be tricky for me to understand specific computing terms. However, I tried to delete what might have been the preference file... there were actually 2 files, one named CACHEDIR.TAG and the other one was plugins-040be.dat . But in another folder, there's a "vlcrc" file... shall I delete one of those files?

delete both

I did but it remains unchanged.
When I click on "Delete_Preferences", an alert message pops up and it reads "Désolé, l'opération n'as pas pu être terminée: une erreur imprévue s'est produite (code d'erreur 2). In short, the opertaion failed due to an error... I still cannot watch videos with VLC...

All right, I finally made it to delete the preferences... but I still don't have the video that appears on the screen... I now have an alert message that reads: "macosx: QT doesn't support any appropriate chroma".
Should I only wait until the next QuickTime release?

I have the same problem. Just downloaded the latest quicktime update and now vlc video (audio is fine) for .avi files doesn't work, with the same message. It seems like quicktime updates mess up a lot of things. I've had problems with realplayer too, in the past. help! I want my vlc back!

Same problem here.
Went to use VLC yesterday and it's screwed. The audio is fine.
I deleted all VLC files off of my mac and reinstalled it but it didn't fix it.
Also tried with an earlier version and still nothing.

I get this message

macosx: QT doesn't support any appropriate chroma

So looks like it is quicktime related. Again.

Anyone?

i haven't ran into the issue, i am running the latest version of VLC and QT 7.4 in both 10.4.11 and in 10.5.1 on a G4 and everything plays fine for me (unless its .mkv or H.264).

I'm running 10.3.9

Have you tried changing the video output module in the Preferences? To do this, go to:
Settings >> Prefereneces... >> Video >> Output modules

And tick the "Advanced options" tickbox. Select a different module (not sure what they are for Mac) from the "Video output module" drop-down box and press "Save". Restart VLC and try a video.

Cheers, Arite.

Hiya.
Nah that didn't work. I was using default settings for video output so didn't know what to change it to. Just picked one at random.
Still got the audio and no video.
Gonna have to do what I did last time and use pacifist to install quicktime 7.3 and overwrite 7.4

You lose the security updates that come with 7.4 but it works.
Mac need to sort their act out.

download pacifist here: http://www.charlessoft.com/
download 7.3 here...

Panther: http://www.apple.com/support/downloads/ ... nther.html
Tiger: http://www.apple.com/support/downloads/ ... tiger.html
Leopard: http://www.apple.com/support/downloads/ ... opard.html

Once quicktime is downloaded open Pacifist. Once open click "open package"... from the menu select the quicktime icon (?) in the left column and double click the package icon.

You then need to click "Install" in the top left of the Pacifist menu.

You'll be asked if you want to replace existing files, click yes to all and Pacifist will take it from there.

Thank you Leah,worked like a charm.
Well seems like no more security update for quicktime for me,thank you...
BTW I beleave the problem described in this thread seems to occur on OS X 10.3.9 only.
cheerz,
breakdown

I have the same problem and it's true of OS X4.1.1, as well. Suddenly today, no video and on the heels od updating QT too (which has been useless to me for the longest time btw.)

In my case I followed the "pacifist"/QT 7.31 etc... instructions, which as far as I know went smoothly, just as Leah described... but the problem persists. Maybe I need to delete VCL software and reinstall from scratch?

Edited to say things have gottten worse. As of today, I can't launch Mac Mail from anywhere OR System Preferences from the Apple drop down Menu, although the preference folder is still in my HD with all the data Also the icons (top right) from my finder menu are gone.

Things have gone from bad to worse. Now Mac Mail won't launch from anywhere and I can't access Systems preferences at all either. I also notice all related icons are gone from the menu at top of the finder. Any suggetions.

BTW I beleave the problem described in this thread seems to occur on OS X 10.3.9 only.

I followed Leah's advice and replaced QT with the previous version using Pacifist, but VLC still plays audio without video and begins processing of each file/disc with the error, "macosx: QT doesn't support any appropriate chroma" (on files and DVDs that worked fine a week ago).

I am on OS-X version 10.3.9 with VLC version 0.8.6c and now QuickTime 7.3.1. Also have noted VLC is crashing in just about every instance AND the Chroma player works fine on all media.

Are there any other possibilities to pursue?--I don't understand how some people were successful regaining video, whether there was something I missed. Would portions of any log/config files help, and if so, let me know which ones and I'll post them here. Thanks.

To clarify, the crashing doesn't happen every time and seems unrelated. Also, I've verified MPlayer works fine. VLC still no video.

I turned on debug and will post log output from the mac.

Log output from one session where VLC played audio but no video below. Hope there's something obvious:

Argh.
Have been putting of updating quicktime for a while since i don't use it at all really, but have recently got an ipod video
and have been having trouble importing videos into itunes. So, i thought I may need to update quicktime but surprise surprise, i have no video with just audio again with VLC.

Anyone else have this problem again (or for the first time) since updating quicktime?
