How to fix a corrupt 3gp File

3gpvideo

My phone ran out of space when recording a video. I have the 3gp file, but cannot open it. Any hints on how to open it an convert it into a working file?

Try using ffmpeg and see if it can copy the file to another container - maybe only the container is broken. 3GP should be easy to convert to MP4.

ffmpeg -i input.3gp -c copy output.mp4

Try ffmpeg:

ffmpeg -i in.3gp -c:a libmp3lame output.mp3

If you are on Ubuntu, you can install avconv instead of ffmpeg, since Ubuntu ships an outdated version of the latter.

If you have a Debian-based Linux, you can use untrunc. Open up a terminal window and run the following commands, one by one:

sudo apt-get install libavformat-dev libavcodec-dev libavutil-dev
cd ~
wget https://github.com/ponchio/untrunc/archive/master.zip
unzip master.zip
cd untrunc-master
g++ -o untrunc file.cpp main.cpp track.cpp atom.cpp mp4.cpp -L/usr/local/lib -lavformat -lavcodec -lavutil
chmod +x untrunc

Now, you need:

the broken file
a correct file – you just need a working file that you obtained from the same device

Put both into the untrunc-master directory. Then, run:

./untrunc correct.3gp broken.3gp

This will output a bunch of info, and it should give you a broken.3gp_fixed.mp4 output file.
