3gpp -> unfinished video (battery shutdown)

[alebm]

Hello,

I was recoding a video with my phone and the battery became weak... the phone done an automatic shutdown. Apparently the video file was not correctly finished. No program that I tried can open the file(including phone's realplayer).
Someone know a trick or a recovery software for this kind of format? I have no experience with 3gpp format, the only thing I know is that copying header and tail from another good file doesn't work.

mplayer output:
MOV: missing header (moov/cmov) chunk! Maybe broken file...
libavformat file format detected.
LAVF: no audio or video headers found - broken file?

when I tried to overwrite a exact size piece over a good file, mplayer give me lots os errors(and really bad video output hehe):
Error while decoding frame!

I am not advance on ffmpeg but maybe ffmpeg with 3gpp enable can convert your video to another format.

it does not work
need moov header also...

I grabbed the quicktime reference api manual, I will have to code the recover app myself, lots of wasted time hehe. 3gp is horrible to recover, moto did a trick thing writing the moov header in the tail of file, so this header is not present, the worst part will be recostructing the arrays that tell frames size and duration, this last one may be dificult to calculate without decoding the frame. Maybe I can ommit the frame duration and only stick with frame size...

Hi all.
I have recorded a 3gp movie with a Sony-Ericsson mobile phone, and before stopping the recording (when the phone should save the end of the 3gp file, which contains all the frame rate and all movie informations) the battery went off, I recovered the partial file from the memory card but it is unusable, I tried everything available on the internet.
The movie has intact headers, but it lacks the end of file with all the video infos needed to be played.
Can anyone help reconstruct the video?
I can even pay for the solution, this movie is extremely important to me.
Thanks for reading,
Horia.

Hi alebm,

I was wondering if you can share the program that you created to recover damaged 3gp files. I've been searching the internet and you're the only one who was close to my problem. I can send a small donation for the program since I really need it. Hope to hear from you soon.

Thanks!
