videofix - Fix common problems in your MKV files.

Description

videofix automatically fixes common problems in your MKV files, such as:

• Transcode EAC3 tracks to AAC, which is universally supported. Existing EAC3 tracks will be removed if a corresponding AAC track already exists (same language).
• Re-order tracks: tracks are re-ordered so that the output file contains video, audio, and subtitle tracks, in this order.
• Sets tracks of your preferred language as default tracks.
• Removes the default flags on all other tracks.
• Optionally removes all tracks that don't match a specified language.

Installation

Automatic process

To download and install automatically (under /usr/local/bin), just run:

curl -s \
  'https://raw.githubusercontent.com/marcopaganini/videofix/master/install.sh' |
  sudo sh -s -- marcopaganini/videofix

This assumes you have root equivalence using sudo and will possibly require you to enter your password.

To download and install under another directory (for example, $HOME/.local/bin), run:

curl -s \
  'https://raw.githubusercontent.com/marcopaganini/videofix/master/install.sh' |
  sh -s -- marcopaganini/videofix "$HOME/.local/bin"

Note that sudo is not required on the second command as the installation directory is under your home. Whatever location you choose, make sure your PATH environment variable contains that location.

Homebrew

videofix is available on homebrew. To install, use:

brew tap marcopaganini/homebrew-tap
brew install videofix

Manual process

Just navigate to the releases page and download the desired version. Unpack the tar file into /usr/local/bin and run a chmod 755 /usr/local/bin/videofix. If typing videofix doesn't work after that, make sure /usr/local/bin is in your PATH. In some distros you may need to create /usr/local/bin first.

Using go

If you have go installed, just run:

go install github.com/marcopaganini/videofix@latest

Using videofix

Usage is simple:

videofix [options] mkvfile.mkv

The program will use a temporary file on the same directory (and refuse to proceed if that file already exists). Once the process is done, it will replace the original file.

Options:

• --lang: language of the default audio and subtitle tracks. This will cause videofix to set the default flag on all tracks that match the default language, and remove it on all tracks that don't. This makes it easier for players to start automatically on your preferred language.

• --prune: When combined with --lang, this will cause the removal of all tracks that are not in your preferred language. The program will refuse to proceed if this will result in the complete removal of a given track type (like audio or subtitle). Use with care.
