untrunc:还原截断的mp4mov。 改进版的ponchiountrunc

Untrunc ======= Restore a damaged (truncated) mp4, m4v, mov, 3gp video. Provided you have a similar not broken video. And some luck. You need: * Another video file which isn't broken * ~~Basic ability to use a command line~~ ([GUI](#GUI) exists) ## About this fork This fork improves the [original](https://github.com/ponchio/untrunc) in the following: * more than 10 times faster! * low memory usage, fixes [#30](https://github.com/ponchio/untrunc/issues/30#issuecomment-143744821) * easier to build + automated [windows builds](https://github.com/anthwlock/untrunc/releases/latest) * \>2GB file support * ability to skip over unknown bytes * generic support for all tracks with fixed-width chunks (e.g. twos/sowt) * advanced logging system * can stretch/shrink video to match audio duration * compatible with new versions of ffmpeg * handles invalid atom lengths * supports GoPro and Sony XAVC videos * many bugs got fixed, actively maintained ## Building Windows users can download the latest version [here](https://github.com/anthwlock/untrunc/releases/latest).\ In certain cases a specific version of ffmpeg is needed. Untrunc works great with ffmpeg 3.3.9. #### With system libraries sudo apt-get install libavformat-dev libavcodec-dev libavutil-dev # get the source code make sudo cp untrunc /usr/local/bin #### With local libraries Just use following commands, make will do the rest for you. sudo apt-get install yasm wget make FF_VER=3.3.9 sudo cp untrunc /usr/local/bin #### GUI The GUI is optional. It is included in the automated [windows builds](https://github.com/anthwlock/untrunc/releases/latest).\ You will need [libui](https://github.com/andlabs/libui). After that, just do make untrunc-gui #### CentOS 7 sudo yum -y install epel-release && sudo yum -y install git gcc-c++ yasm git clone --depth 5 https://github.com/anthwlock/untrunc && cd untrunc make FF_VER=3.3.9 sudo cp untrunc /usr/local/bin ## Docker container You can use the included Dockerfile to build and execute the package as a container.\ The optional argument 'FF_VER' will be passed to `make`. # docker build --build-arg FF_VER=3.3.9 -t untrunc . docker build -t untrunc . docker image prune --filter label=stage=intermediate -f docker run -v ~/Videos/:/mnt untrunc /mnt/ok.mp4 /mnt/broken.mp4 ## Snapcraft If you have `snap`, you can use `sudo snap install --edge untrunc-anthwlock`. [](https://snapcraft.io/untrunc-anthwlock) ## 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) ### Help/Support #### Reporting issues Use the `-v` parameter for a more detailed output.
