Win32 FFMpeg Makes Invalid MP4 ?

[Endemoniada]

Hi guys, when I use FFmpeg to create an h264 MP4 it won't play in either Zoom Player or JW Player, if however I rename it to an FLV I can play it in JW Player (but still not Zoom Player.) Something isn't right. I think it's the audio codec because I can't use libfaac, it's 'unknown encoder libfaac'.

I tried using Handbrake but I can't set the start time and duration, it only encodes the whole thing which is not what I want.

I can't win.

ffmpeg settings:
ffmpeg -i source.mp4 -ab 96k -vcodec libx264 -fpre slow -crf 22 -threads 0 -y dest.mp4

Aren't you using any -acodec? how about try mp3? or use copy mode?
Where did you download ffmpeg? maybe you can find a ffmpeg version with aac somewhere else.
