No Video after Installing Lion

Hi

I am also having this problem i am trying to play the office from my HDD. before the update it worked now i just get audio please help me i love this show, i want to see it again

Thanks

Yep, same problem here. The video works in VLC, but not in Quicktime. Audio plays, but the screen remains black. It still changes size - i.e. fills the screen when you hit command-F, but it's a full screen of black.

Am having the exact same set of issues. Audio works, video does not in quicktime.

I am having this same issue. Please apple do an update to fix this issue.

I'm having the issue!! I need a fix!

Same issue if anyone finds a solution!

Ok, fixed mine. Go to Library/QuickTime: Remove obsolete QuickTime Components: FFusion, Xvid Delegate, 3ivX, DivX, DivX Decoder, XviD, msmpeg4v1, msmpeg4v2, AviImporter, EX_M4S2, Casio AVI Importer, AC3 Codec, Sorenson and MatroskaQT.

Maybe try one at a time starting with 3ivX

I'm using Perian 1.2.3

All working now.

Thanks for the great tip! I removed the 3ivx plugin and everything was good to go.

I removed the 3ivx plugin and everything was good for me too .

Thanks it works!

I have perian 1.2.3. on LION. I did have DIVX installed but I uninstalled using their uninstall too. I also manually deleted leftovers DIVX folder and plst files in user/library folder. After uninstalling DIVX I rebooted and reinstalled perian. QT plays the video but no audio. The MPLayerX works playing the avi files but wanted to know if QT has a plugin the divx and xvid files will play under Lion.

I posted the following with regards to a similar problem involving Flash's FLV formats, although I do believe I removed 3vix somewhere along the line too… In the case there is more than one issue at work here:

There seems to be an issue with the version of Quicktime X (10.1) in Lion and Perian version 1.2.3.

The are several options in terms of other media players (VLC, MPlayerX, RealPlayer [ugh…], and others…) that will handle FLV files with ease. Alternatively, you could run your video files through an encoder (HandBrake, MPEG Streamclip, SmartConverter, etc.) converting the files into something QuickTime naturally understands like an MP4 or MOV.

But, you were probably happy when everything just worked with the QuickTime / Perian dynamic duo and just want it the way it was. It seems the best way to make this happen, is to go back to using Perian 1.2.2, for the moment anyway. Seems to do the trick for anyone with this problem, so…

1. Remove Perian 1.2.3 from the system.

Quit all your apps, expecially QuickTime. Open System Preferences and click on Perian. You're looking for the "Remove Perian" button; just click and if it asks, type your password. Next, back to the main System Preferences screen where you right-click(or control-click) on the Perian icon. A menu pops up with the choice to remove the Preference Pane. Click on it and Perian is officially uninstalled.

2. Restart the computer

Probably overkill, but better than having to repeat the process because you didn't.

3. Download and install Perian 1.2.2

Get it here: http://perian.cachefly.net/Perian_1.2.2.dmg , or here:http://www.videohelp.com/download/Perian_1.2.2.dmg

Once its downloaded mount the disk image, but proceed with care. Perian will likley try to upgrade itself right after you install it. Best thing to do: disconnect from the net for the install process. Then as usual double-click the "Perian.prefpane" file, choose who you'd like to install it for, and enter your password as needed. Finally, right before reconnecting your machine to the world, uncheck the "Automatically Update" box in the Perian preferences.

Try testing one of the FLVs in QuickTime or QuickLook and with a bit of luck, radio becomes TV.

Oh… and on the off chance it doesn't work and you want to watch some FLVs? Use VLC (http://www.videolan.org), or convert them with HandBrake (http://handbrake.fr), but P-L-E-A-S-E don't make yourself use RealPlayer. Put it in the Trash and immediately choose "Secure Empty Trash…" from the File menu. You'll thank me for it, one day.

Good luck!
