iphone video (h.264, aac, .mov) sound issues

[4evrplan]

I'm trying to edit this clip captured on an ipod touch 4g (same format as iphone) with free software (avisynth and virtualdubmod). This is on an XP SP3 machine with ffdshow-tryout beta 7 (decoding aac with libfaad2). I tried opening the original file with no luck, so I used Mp4Cam2AVI to convert to avi and tried that too, also with no luck. Here's my script with comments:

#directshowsource("IMG_0078.mov")  # no audio - stream list empty
#directshowsource("IMG_0078.avi")  # out of sync
#ffmpegsource2("IMG_0078.mov")     # no audio - stream list empty
#ffmpegsource2("IMG_0078.avi")     # no audio - stream list empty
#ffvideosource("IMG_0078.mov")     # no audio - stream list empty
#ffvideosource("IMG_0078.avi")     # no audio - stream list empty
#avisource("IMG_0078.avi")         # w/o aacacm installed - "No compatible ACM codec to decode 0x00FF audio stream to PCM"
                                   # with aacacm installed - "ACM reported error on audio decompress"

Can someone please explain to me (like you would to a slow child please) how to get this working with free software?

ffmpegsource2 and ffvideosource both ignore audio by default - you need to add atrack=-1.

If you still have problems after that, what does MediaInfo (use search if you don't know what that is) say about your audio track? Post a text listing here.

That did the trick (I know, I know - RTM, right). Thank you for your help.
