the file wasn't closed correctly
the only thing i know, would be to use a HEX editor
open a good avi from the same source
and compare the opening header and the closing/end of file

of the the two avi files

the header usually contains the file info
such as file length (number of bytes)
and at what position the file actually starts (hex address of the start of the AVI file )
and other data

Hi jamespoo

Looks like your 3gp file got corrupted. I would suggest to try to diagnose it for free using MP4repair.org. Then decide whether is worth to pay or not.

According to the post "How to repair damaged .3gp files" on their blog you could also try to change the container using ffmpeg to see if that would help.

ffmpeg -i input.3gp -vcodec copy -acodec copy output.mp4

Best of luck!
