I'm sorry, but I still can't get it to work??? It just doesn't sync with the iPhone.

This is what I tried. First I encode the video to mp4 like this. The avi suggestion didn't work.

mencoder movie.mov -o output.mp4 -vf scale=480:-10,harddup -lavfopts format=mp4 -faacopts mpeg=4:object=2:raw:br=128 -oac faac -ovc x264 -sws 9 -x264encopts nocabac:level_idc=30:bframes=0:global_header:threads=auto:subq=5:frameref=6:partitions=all:trellis=1:chroma_me:me=umh:bitrate=500 -of lavf

Then using mp4box to extract those tracks.

MP4Box -raw 1 output.mp4
MP4Box -raw 2 output.mp4

and mux back with mp4box

MP4Box -new remuxed.mp4 -add output_track1.h264 -add output_track2.aac -fps 25.0 -ipod -mpeg4

Still not working. I even added the ipod flag, but no success. Any idea? Does this work for anyone?

Looking forward to a solution before I start to tear my hair.
