Before we jump on the video repair part, it is imperative to understand FFmpeg, what it is and what we can use it for?

What is FFmpeg?

FFmpeg, a software endeavor, encompasses libraries and software tools for managing various multimedia components such as video, audio, and streams. It operates under either the GNU Lesser General Public License 2.1+ or the GNU General Public License 2+, contingent upon the activated options. The moniker “FFmpeg” draws inspiration from the MPEG video standard, with “FF” denoting “Fast-Forward.”

What is FFmpeg used for?

FFmpeg is inherently crafted for command-line usage, eschewing the need for a specialized GUI. Its applications encompass video and audio file processing, format transcoding, fundamental editing, video scaling, integration of post-production effects, and adherence to standards such as SMPTE and ITU.

FFmpeg encompasses components such as libavcodec and Lavf, serving as a library for audio/video container multiplexing and demultiplexing. Additionally, it includes a command-line program for FFmpeg, enabling transcoding of multimedia files. The libavcodec library is widely adopted for audio/video encoding and decoding, commonly utilized in both commercial and free software products.

Things Possible With FFmpeg

  • Listen to text using a chosen voice.
  • Modify, adjust, or remove file information.
  • Incorporate a logo or set up Picture in Picture (PiP).
  • Generate digital audio through mathematical expressions.
  • Utilize one or multiple webcams and seamlessly stream their input within a single interface.
  • Apply filters to multimedia files, perform encoding, decoding, transcoding, multiplexing, demultiplexing, and streaming.
  • Transform video into individual frames and vice versa.
  • Alter or adjust frame rate, bitrate, maximum file size, and related parameters.

How to Repair Corrupt Video File Using FFmpeg

Now that you have a foundational understanding of FFmpeg, let’s proceed to the steps for repairing and recovering corrupt or damaged video files. The prerequisite before we begin is ensuring FFmpeg is installed on your system.

The outlined process entails two distinct stages. Initially, we will transform the video into static images, and subsequently, we will reverse this transformation to recreate the video.

Convert Video to Still Images

Assuming you’ve downloaded the FFmpeg zip package and extracted it somewhere, now place the corrupt or damaged video file in the bin folder.

  1. Hold the Shift button and select Open command from right-click menu.
  2. Type the following command in command prompt:
    .\ffmpeg.exe -i .\videoname.wmv -an -f image2 filename%03d.jpg

The video is now converted into multiple images – stills, 99,739 stills were created, before moving to the next stage:

Extract Audio

Below command will initiate the audio extraction:

.\ffmpeg.exe -i .\videoname.wmv audio.mp3

Figure out the exact audio duration:

.\ffprobe.exe -i .\audio.mp3 -show_entries format=duration -v quiet – print_format json

The output will be something like below though; the numbers would be different depending on the duration of your video file:

{
“format”: {
“duration”: “3323.603000”
}
}

Now, before we start converting the stills back as the video, we need to calculate the frame rate of output video, so that both the audio & video can match.

For doing so, divide the number of stills by the audio duration number:

In this case, it is 99739 divided by 3323.603 which will be 3.0093, type the command as below:

.\ffmpeg.exe -framerate 30.0093 -f image2 -i .\filename%03d.jpg -codec copy output_noaudio.mkv

Convert the Stills Back to a Video

In the final stage, mix the audio & video to construct the repaired video file, type the command below:

.\ffmpeg.exe -i .\output_noaudio.mkv -i .\audio.mp3 -c copy -map 0:v:0 -map 1:a:0 output.mkv

You have effectively restored a corrupted video utilizing FFmpeg via command-line operations. FFmpeg offers various techniques to tackle video file corruption. While FFmpeg proves more efficient than manual methods in resolving video corruption problems, it cannot guarantee a solution for every video issue or error. In cases where the video file is severely corrupted and irreparable, we recommend using a specialized tool like Video Repair for optimal results.
