MP4 just audio no video

Postby asoksevil » Fri Dec 31, 2010 11:20 am

It's a H264 video and AAC audio. I don't know why, but it just won't play. I already have Perian, QuickTime Preferences and Fli4Mac WMV. Weird thing is that I tried another MP4 with H264 and it plays with no problems.

Try running this in Terminal (cmd-shift-U -> Terminal):

Code: Select all

defaults write org.perian.Perian DecodeAllProfiles -boolean YES

If that doesn't work, can you post the file to Mediafire and link it here?

The command to undo the above:

Code: Select all

defaults delete org.perian.Perian DecodeAllProfiles

Return to “Perian”
