All features


You need:

Another video file which isn't broken
libav
Basic ability to use a command line
Installing on Ubuntu



If you have an old Ubuntu version or other operational system, you might need to manually install a recent libav version, go to the bottom of the page for instructions.

Install some pre-requisite libraries with this command:

sudo apt-get install libavformat-dev libavcodec-dev libavutil-dev

Download the source code from GitHub at https://github.com/ponchio/untrunc

wget https://github.com/ponchio/untrunc/archive/master.zip

Unzip the source code:

unzip master.zip
Go into the directory where it's been unzipped:

cd untrunc-master
Compile the source code using this command (all one line):

g++ -o untrunc file.cpp main.cpp track.cpp atom.cpp mp4.cpp -L/usr/local/lib -lavformat -lavcodec -lavutil



Installing on other operating system (Manual libav installation)

Download the source code from GitHub at https://github.com/ponchio/untrunc and unzip the source code.

Download libav, 0.8.7 version from libav download page and unzip into the untrunc source code library. Then:

cd untrunc-master
Build the library

cd libav-0.8.7
./configure
make
cd ../
Build untrunc

g++ -o untrunc file.cpp main.cpp track.cpp atom.cpp mp4.cpp -I./libav-0.8.7 -L./libav-0.8.7/libavformat -lavformat -L./libav-0.8.7/libavcodec -lavcodec -L./libav-0.8.7/libavutil -lavutil -lpthread -lz



Arch package

Jose1711 kindly provides an arch package here: https://aur.archlinux.org/packages/untrunc-git/

Using

You need both the broken video and an example working video (ideally from the same camera, if not the chances to fix it are slim).



Run this command in the folder where you have unzipped and compiled Untrunc but replace the /path/to/... bits with your 2 video files:

./untrunc /path/to/working-video.m4v /path/to/broken-video.m4v
Then it should churn away and hopefully produce a playable file called broken-video_fixed.m4v

That's it you're done!

(Thanks to Tom Sparrow for providing the guide)
