HT3775 not playing AVI files

I have an AVI file that is not playing in QuickTime player.
The error message says 'A required codec isn't avalible'. Why is that?

Because there isn't a codec installed for that specific AVI; as AVI is a container, not a format, it's impossible to be certain, but it's most likely either part of Perian or doesn't exist for Mac OS X.

I am using OS 10.7 Lion. Quicktime will not play avi files. One support forum gave 2 links to get them but I got a 404 error. Can anyone help?

You can also use VLC

It woks very well, can read almost anything, and also lets you do conversions to other formats.

My QuickTime player us not playing .avi files and says I need a codec I can't play no .avi files on QuickTime. How could I fix this because I want to play these files with QuickTime.

Hmm . . . comes with a Utility MPEG2 Component ML app with no explanation of what it's for?
The utility app is an "assistant PKG installer." It allows Lion and Mountain Lion users to install the older QT MPEG-2 Playback Component installer PKG file which is not allowed to run on its own under Lion or Mountain Lion since these operating systems already have a QT X only MPEG-2 component embedded in the QT embedded structure. Without this utility you would have to either copy the component from an older system to your Lion or Mountain Lion system, use Pacifist for installation, or manually open the PKG contents and transfer the component to the appropriate component folder.
As to your "discussion" regarding the playback of AVI file types, there are really only two strategies here:
1) You can add component support so that QT can play the files natively or
2) You can convert the file contents to compression formats that are natively compatible with the unmodified QT component configuration.
Each user should decide for his or her own self which approach best suits their needs for a particular source file. In most cases, conforming the system's codec component configuration to play the source file directly results in higher video quality since no transcoding takes place but this strategy will not work if a codec which is required is not available for the user's operating system. On the other hand, converter utilities tend to support more built-in codecs and are easier to use since the user does not have to concern him or herself with the nature of the particular source compression formats but at the risk of some potential loss in visual quality. As to what converter to use, once again this is a matter of personal choice. In the case of commercial converters like iSkysoft, the codecs are built in while MPEG Streamclip accesses the host operating system's QT codec component configuration. I personally prefer the free HandBrake app for AVI, MKV, TS, MTS, and M2TS conversions since it has an exceptionally full-featured X.264 GUI with some user options that 97% of users are likely to never use.

Quicktime 10.1 not playing .avi files

My quicktime player isn't playing .avi files properly. I have perian installed and have been playing .avi files on my MacBook Pro fine now for over 2 years. However, I resently installed Lion and it doesn't seem to be working now. I've looked around and it seems there are some bugs with Perian and Lion, however I haven't seen mine. Quicktimes loads, loads the video, I can click anywhere on the timeline and see the video, however when I hit play, it immediately pauses itself and won't play. Sometimes it will play very brieftly, about 1/10 of a second, and then flicker back to paused. Is there any other integrated solution to Perian? Was hoping to not have to get VLC player.

I had this same problem and someone on here helped me solve it.
As stated, I did not have any problem and could not duplicate the original poster's problem.
See if you have DIVX For Mac installed.
Negative. I do not have any DivX components installed and am using Perian for playback. AVI (DivX5/MP3) files were created using Visual Hub under Snow Leopard. And, if I cannot get Visual Hub to work under Lion (PPC version is not Lion compatible), then I will drop AVI altogether since I only use it to send my sister clips.

Can not play avi files; please help!!

i have a imac with Mac OS X 10.4.11; i can't get sound on any avi files, if take a mov file and convert it to avi, no sound; a friend give a disc with several avi movies, but i dont hear anything.
can anybody help me please

Download and install Perian from http://perian.org/
You should read this support page http://perian.org/#support in case you need to delete older codecs.
In Macintosh HD/Library/Quicktime/ delete any files relating to DivX (Perian already has them). However it should be noted that Perian is not an internet plugin and will not play DivX files imbedded on a website. For that you will need the DivX Player browser plugin available from http://www.divx.com/divx/mac/

Quicktime not playing .avi file!

I have been trying to figure out why it doesn't play for a day now. The thing is, it only doesn't play this .avi file, others I have can play it. It says it needs another component to play it and directs me to the extra quicktime downloads page, but I don't know which one I need. I tried downloading the XviD component, but now it says "Movie cannot be opened. Mac OS Error -1." I need help!

I just solved this issue on my machine. Something in the Perian bundle also conflicts with Intel core MacBooks. I finally resolved the issue and avoided the white screen by removing ALL 3rd party QT plugins (including Perian) and restarted. I was then able to view the AVI files and avoid the white screen. When I added back Perian, I could again not see the files. So, the solve is remove ALL QT 3rd party plugins. I suppose you can add Perian back after you have used the files you require, but be aware there is still an Intel conflict within Perian for certain AVI files.

HT3775 My Macbook Air (still with Lion) will not play .avi video files

My Macbook Air (still with Lion) will not play .avi video files (brought over from an older PC where they play with another viewer). This site implies Quicktime Player should be able to do so. Is there a codec or something else I'm supposed to download?

I had found this through other threads, but it is what worked, even allowed my AVI files to be played in PowerPoint. Changing to 32-bit encryption did not work, BTW.

HT3775 I have an .avi file Quicktime is refusing to play, yet the information says Quicktime does play .avi files. Does anyone know what the problem is?

AVI is a legacy file container originated by Microsoft back in 1992 and which has not been officially supported for more than a decade. Like the container, many of the codecs commonly used to create AVI content are also "legacy" compression formats most often supported on PC/Windows platforms. In fact, some codecs have never been transcoded for Mac use. Of those that have, many never made the transition to Mac OS X or the transition to Intel-based platforms. Those codecs that are still supported on the Mac can normally be found in the avi to quicktime converter available as an online download. While some common AVI compression formats may be supported by the QT X Player app, QT 7 currently provides a more compatible AVI playback environment for most "legacy" compression formats. If the codec(s) used in your AVI files are not supported by the avi to quicktime converter for QT use, you can try the VLC media player which may still support more esoteric compression formats. If VLC does not support the files, the normal approach is to discover which specific audio and/or video codecs were used to create the file and perform an Internet search to see if a compatible Mac component is available for download.

HT3775 Quicktime 10.2 (603.6), it won't play .AVI files

I have Quicktime 10.2 (603.6), it won't play .AVI files, tells me "file format isn't recognized" the above article says it does play .AVI files, what gives?

There isn't a codec installed which can handle that specific AVI file; AVI is a container, not a format. Try installing Perian.

Depends of the specific kind of file you are trying to play. MOV refers to the file container. Any data compatible with the system used to create the file can be placed in an MOV file. If you don't have the same codecs available on your computer to play back the file or if your version of the QT player does not expect expect the encoded data to be in an MOV file container, then it cannot/will not play the file. Use the Finder Info window, media player Inspector/Information window, or a dedicated utility to determine what compression formats were used to create the MOV file and then install the required codec(s) if available.

I was wondering if i plug a hard drive into my apple extreme will i be able to play avi file from it via an apple tv?

I am in the market for a TV media player. I have a lot of videos and photos on an external HDD and i would love to be able to play them on my big new TV. I have been thinking about buying a "Buffalo home theatre" or a "WD TV Live". BUT..... I would like to stick to my Apple products and so was wondering if ...
a) You can plug a HDD into an Apple Airport Extreme. I currently have an Airport Express but want to upgrade.
b) If i plug a HDD into an Apple Airport Extreme, would I then be able to Access the avi and mkv files from my HDD and play them through Apple TV.
Does that make sense?
I wish the apple TV had a usb port, that would solve my problem.

Welcome to the Apple Community.
Yes you can plug a drive into an extreme, but the Apple TV will not play AVI (with noted exception) or mkv files.
H.264 video up to 720p, 30 frames per second, Main Profile level 3.1 with AAC-LC audio up to 160 Kbps per channel, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats

Please help! Playing .avi files in QT Pro

I have installed Perian, been to the Apple Store, and searched high and low for the answer, but cannot figure out how to play .avi files in QuickTime Pro. It's only some .avi files (not all), I can hear the background noise, but the screen is black. Please tell me how to remedy this.
Thank you,

'avi is simply a container that can contain any number of different video codecs. Most, but not all, can be played on a Mac.
These are the downloads and the settings you need in order to view/hear/play pretty much everything that the net can throw at you: The setup described below has proved repeatedly successful on both PPC and Intel macs, but nothing in life carries a guarantee!
It is known to work in the great majority of cases with Safari 3.2.1 and 4, QT 7.4.x, 7.5.x and 7.6 and OS 10.4.11 and 10.5.6.
Download and install (or re-install even if you already had them) the latest versions, suitable for your flavor of Mac, of:
RealPlayer 11.1 for Mac from:
http://www.versiontracker.com/dyn/moreinfo/macosx/15540
Flip4Mac WMV Player from http://www.telestream.net/flip4mac-wmv/overview.htm (Windows Media Player for the Mac is no longer supported, even by Microsoft)
Perian from http://perian.org/
You should read this support page http://perian.org/#support in case you need to delete older codecs.
The latest version of Adobe FlashPlayer can be obtained from here:
http://www.adobe.com/shockwave/download/download.cgi?P1ProdVersion=ShockwaveFlash
(You can check here: http://www.adobe.com/products/flash/about/ to see which version you should install for your Mac and OS.
Note that Adobe requires you to uninstall any previous version of Flash Player, as mentioned here:
http://kb.adobe.com/selfservice/viewContent.do?externalId=tn_14157&sliceId=1
using the uninstaller from here (make sure you use the correct one!):
http://kb.adobe.com/selfservice/viewContent.do?externalId=tn_14157
and also that you follow the instructions closely, such as closing ALL applications first before installing. You must also carry out a permission repair after installing anything from Adobe.
You should also ensure that you have downloaded and installed the correct version for your Mac of Security Update 2009-001. (N.B. Security Updates require both a restart and a permission repair.)
In Macintosh HD/Library/Quicktime/ delete any files relating to DivX (Perian already has them). However it should be noted that Perian is not an internet plugin and will not play DivX files imbedded on a website. For that you will need the DivX Player browser plugin available from http://www.divx.com/divx/mac/
Now go to Safari Preferences/Security, and tick the boxes under Web Content (all 4 of them) to enable Java.
Lastly open Audio Midi Setup (which you will find in the Utilities Folder of your Applications Folder) and click on Audio Devices. Make sure that both Audio Input and Audio Output, under Format, are set to 44100 Hz, and that you have selected 'Built in Audio'.
Important: Now repair permissions and restart.
You should also consider having the free VLC Player from http://www.videolan.org/ in your armory, as this plays almost anything that DVD Player might not.
There is an additional 'fix' you could try if you are having problems with Flash and Quicktime, depending on which type of Mac you have:
On Intel Macs, make sure that you are not running Safari in Rosetta. You can check this, and change it, in the Get Info window.
On PPC Macs, go to the Hard Disk/Library/Internet Plug-Ins folder, and drag the file 'QuickTime Plugin.webplugin' to the desktop. Quit and restart Safari. If things have improved you can trash that file. If they haven't put it back, as the lack of this plug-in can cause QT content in some widgets to cease functioning.
And there is an additional kid on the block: SilverLight. Microsoft has created their own version of what a replacement for Flash could be. You can read more about it here:
http://silverlight.net/
So, if you go to any sites that have been designed for this new Silverlight stuff, you can download the plug-in from here (but make certain that you are downloading SilverLight v.1.0 for OS X (10.4.8 upwards) if you are using a PPC Mac. Version 2 only works with Intel Macs:
http://silverlight.net/GetStarted/
Recommendation: Close all applications before installing any of the above, repair permissions, reboot, and repair permissions again.
