Compiling Av1an
You can natively build Av1an on Linux and Windows. Cross-compilation is not supported.
Compiling on Linux
To compile Av1an from source, you need the following dependencies:
- Rust (version 1.70.0 or higher)
- NASM
- clang/LLVM
- FFmpeg
- VapourSynth
On Arch Linux, you can install these dependencies by running
pacman -S --needed rust nasm clang ffmpeg vapoursynth
Installation instructions on other distros will vary.
After installing the dependencies, you need to clone the repository and start the build process:
git clone https://github.com/master-of-zen/Av1an && cd Av1an
cargo build --release
The resulting binary will be the file ./target/release/av1an.
Compiling on Windows
If you just want a current build of Av1an that is newer than the last official release, you can find a pre-built binary of the current master branch at https://github.com/master-of-zen/Av1an/releases/tag/latest.
If you want to build the binary yourself, you will need the following dependencies:
- Microsoft Visual C++ Build Tools - this is a dependency for Rust
- The Rust toolchain
- Python (version 3.8 or 3.10) - this is a dependency for VapourSynth. Recommended to install for all users
- VapourSynth
- NASM
- FFmpeg (thanks to gyan for providing these builds)
Extract the file ffmpeg-5.0.1-full_build-shared.7z to a directory, then create a new environment variable called FFMPEG_DIR (this can be done with with the "Edit environment variables for your account" function available in the control panel), and set it to the directory that you extracted the original file to (for example, set it to C:\Users\Username\Downloads\ffmpeg-5.0.1-full_build-shared).
Then, either clone the repository by running
git clone https://github.com/master-of-zen/Av1an
Or download and extract the source code manually.
Open a command prompt or PowerShell window inside the cloned repository/extracted ZIP folder and run the command cargo build --release. If this command executes successfully with no errors, av1an.exe will be in the folder target\release.
To use av1an.exe, copy all the .dll files from ffmpeg-5.0.1-full_build-shared\bin to the same directory as av1an.exe, and ensure that ffmpeg.exe is in a folder accessible via the PATH environment variable.
