QuickTime Player – Error Message – A required codec isn’t available
Using QuickTime, tried playing some AVI files on Mac OS X, but I keep getting this error message:
A required codec isn’t available.
Clicking on the “Tell Me More” button, landed me @
As I am trying to play AVI files, I chose to try Telestream’s “Flip4Mac” or Divx’s Divx for Mac.
Other web site’s suggests to try http://perian.org/.
Tried Flip4Mac, but no joy.
Next tried Divx’s. Worked well showing the video, but unable to hear Audio; as this message came up:
You may need an additional audio decoder to play the soundtrack of this file.
This file contains a track in the Dolby AC3 Audio (code “8192”) format.
An earlier Googling had brought me this joy:
Watching AVI Movies in Mac OS
- liba52 – a free ATSC A/52 stream decoder
- QT AC3 Codec
To install the codec, follow the guideline available @
- Open Finder
- Navigate to “Macintosh HD” \ Library \ QuickTime
- Copy the downloaded component “AC3 Codec.component” from your Downloads folder
- Restart the computer
You might have to authenticate.
If so, just provide your username and password.
Once I followed the steps, I tried again to play and see if I could the the Audio.
But, still no joy.
And, all I really could mutter is what an opaque system. It seems QuickTime does not ‘ve a built in Interface for reviewing which codecs are “in-play”.
So hear we go … restarted the system; to ensure that the codecs has the best chance of being used.
Hopefully, on the other side, audio will show up .. or better said … play.
But, upon reboot, still no audio.
So went with Perian.Org. It installed and I could hear music.
Btw, Perian.Org is no longer in active development. But, still, the current version is really usable enough.
