ffmpeg faac frame decode failed

[fobster]

Hi,

I was wondering if anyone has ran into this problem before. I get an error that basically messes up the audio of the transcoded video. This is the error I am getting:

faac: frame decoding failed: Array index out of range Error while decoding stream #0.0

Does this generally happen if the source is prepared as a streaming video rather than a progressive download video?

The following is portion of the log:

I've never had good luck decoding aac with ffmpeg. The best utility I've found for that purpose is called FAAD . Convert the output to WAV, or pipe the output back into ffmpeg. You'll have some syntax experimentation ahead of you, but it'll probably work better than ffmpeg alone.

Here is a GUI for faad called Ivan & Menno. It is just a GUI so you will have to download faad seperatly from rarewares.org
