GAV

GAV is a simple audio and video player, backed by FFmpeg and Qt6.

Usage

From command line:

# Play a video or audio file
gav <file>

# Create a collage from video files
gav --collage <file1> <file2> ...

# Create collages from all videos in a folder
gav --collage <folder>

Or open a file from the menu.

Collage Creation

GAV can create thumbnail collages from video files. A collage is a grid of video frames extracted at evenly distributed timestamps, along with metadata (filename, duration, resolution, codecs, file size).

CLI Usage:

• Process individual files: gav --collage video1.mp4 video2.mp4
• Process all videos in a folder: gav --collage /path/to/video/folder
• Mix files and folders: gav --collage video1.mp4 /path/to/folder video2.mkv

Supported video formats: mp4, avi, mkv, mov, wmv, flv, webm, m4v, mpg

Build

Note

Requires CMake 4.0 or higher.

Requirements

• Qt6 with QtMultimedia module
• CMake 4.0 or higher
• vcpkg
• Ninja (optional, but recommended)
• Visual Studio 2022 or higher / GCC 10 or higher / Clang 10 or higher (depending on your platform)

Building with vcpkg and Ninja

Intsall your vcpk in user folder and run the following code:

cmake -B build -DCMAKE_TOOLCHAIN_FILE=$HOME/vcpkg/scripts/buildsystems/vcpkg.cmake -G Ninja -DCMAKE_TOOLCHAIN_FILE=$QT/lib/cmake/Qt6/qt.toolchain.cmake -S .
cd build
ninja

Add -DCMAKE_BUILD_TYPE=Release to the cmake command for a release build.

This should install any required dependencies automatically and build the project.
