opustags

View and edit Opus comments.

The current code quality of this project is getting better, and is suitable for reliably editing any Opus file provided it does not contain other multiplexed streams. Only UTF-8 is currently supported.

Until opustags becomes top-quality software, if it ever does, you might want to check out these more mature tag editors:

• EasyTAG
• Beets
• Picard
• puddletag
• Quod Libet
• Goggles Music Manager

See also these libraries if you need a lower-level access:

• TagLib
• mutagen

Requirements

• a C++14 compiler,
• CMake,
• a POSIX-compliant system,
• libogg.

Installing

opustags is a commonplace CMake project.

Here's how to install it in your .local, under your home:

mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=~/.local ..
make
make install

Note that you don't need to install opustags in order to run it, as the executable is standalone.
