## Overview

This repository provides a comprehensive build system for FFmpeg and FFmpegKit that supports multiple platforms and architectures. The system handles the complete build pipeline from toolchain installation through dependency compilation to final bundle creation, with support for both native Linux builds and cross-compilation to Windows from Linux hosts, native MacOS build, cross-compilation to iOS on MacOS host, and cross-compilation to Android on Linux host.

## Platform Support

- **Linux**: Native builds for x86_64 architecture with shared libraries (.so) and static libraries (.a).
- **Windows**: Cross-compilation from Linux hosts using MinGW-w64 toolchain with shared libraries (.dll) and static mingw libraries (.a).
  - *Note: Compiling using MSVC ABI is not supported by the build script.*
- **Apple**: MacOS and iOS build scripts must be run on a MacOS to.
  - **iOS**: iOS-Simulator (arm64) fully supported to deploy on simulator builds.

| Platform                 | Status      | Architecture                                        | Min Version |
| ------------------------ | ----------- | --------------------------------------------------- | ----------- |

## Quick Start

### Prerequisites

- **OS**: Linux host or WSL2 ([manylinux](https://quay.io/organization/pypa) recommended for maximum compatibility - use docker/devcontainer if unsure).
- **RAM**: 8GB+ recommended for linking static binaries.
- **Disk Space**: ~285GB available disk space for a full build with all dependencies and intermediate object files.
- **Custom Build**: bundle build sequence has already been organized in a way that accounts for dependencey tree. I have done my best to include dependencies in individual build steps but if you make a custom build with custom components enables/disabled you may run into dependency issues. You will have to troubleshoot those on your own.
- **Dependencies**: you will need the following dependencies:

```bash
# Run as root/sudo
# update
apt-get update
# install deps
apt-get install -qq --no-install-recommends ragel pkg-config make autoconf automake yasm cvs flex bison texinfo ed pax unzip patch wget xz-utils nasm gperf autogen bzip2 clang bc autopoint zstd curl git subversion libtool-bin build-essential cmake software-properties-common python3 coreutils python3-pip apt-transport-https ca-certificates python3-setuptools ninja-build autoconf-archive g++ gcc gettext help2man libtool p7zip-full python3-venv binutils llvm lld python3-numpy cython3 shellcheck xutils-dev libssl-dev zlib1g-dev libglib2.0-dev libglib2.0-dev-bin libgtkmm-3.0-dev libsdl2-dev
```

## Compiler Toolchain

### Windows (Cross-Compile)

Windows builds use the MinGW-w64 GCC 15.x toolchain. If running on a native Linux host (not a pre-configured Docker container), you **must** install the toolchain manually:

```bash
# Run as root/sudo
apt update && apt install binutils

# Download MinGW-w64 GCC 15
wget https://github.com/xpack-dev-tools/mingw-w64-gcc-xpack/releases/download/v15.2.0-2/xpack-mingw-w64-gcc-15.2.0-2-linux-x64.tar.gz
mkdir -p tools
tar xf xpack-mingw-w64-gcc-15.2.0-2-linux-x64.tar.gz -C tools
rm xpack-mingw-w64-gcc-15.2.0-2-linux-x64.tar.gz

# Install to /usr/local
mv tools/xpack-mingw-w64-gcc-15.2.0-2 /usr/local/mingw-w64
chown -R root:users /usr/local/mingw-w64
chmod -R 775 /usr/local/mingw-w64
```

### Rust Toolchain

Many modern multimedia libraries (rav1e, dovi_tool) require Rust.

```bash
# Run as root/sudo
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- -y --no-modify-path
source $HOME/.cargo/env

# Add Windows target for cross-compilation
rustup target add x86_64-pc-windows-gnu
# rustup target add i686-pc-windows-gnu # Uncomment for 32-bit builds

cargo install cargo-c
```

### Using the Unified Entry Point

The `runner.sh` script is the unified entry point for all builds. It can be used interactively or with explicit command-line options. Note that the script requires `sudo` privileges to install system packages and configure the build environment.

### Common Build Scenarios

```bash
# Interactive mode - prompts for platform and architecture
sudo ./runner.sh

# Non-interactive mode: Build GPL version with audio libraries for Linux x86_64
sudo ./runner.sh --host=linux --arch=x86_64 -y --enable-gpl --enable-audio

# Build for Linux with specific additional libraries
sudo ./runner.sh --host=linux --arch=x86_64 --enable-fontconfig --enable-freetype

# Force re-build for Linux (all libraries + FFmpegKit) with hardware acceleration
sudo ./runner.sh --host=linux --arch=x86_64 -f --video-hw-bundle

# Create a redistributable release zip
sudo ./runner.sh --host=linux --arch=x86_64 --full-bundle --release

# Force build Full non-free dependencies for windows 64 bit
sudo ./runner.sh --host=windows --arch=x86_64 --enable-full --enable-nonfree -y --build-deps-only -f

# Force build static Ffmpeg libraries and programs for windows 64 bit
sudo ./runner.sh --host=windows --arch=x86_64 --enable-full --enable-nonfree -y --build-ffmpeg-only=static -f --programs

# Force build shared Ffmpeg-kit library for windows 64 bit
sudo ./runner.sh --host=windows --arch=x86_64 --enable-full --enable-nonfree -y --build-ffmpeg-kit-only=shared -f

# resume previous failed run
sudo ./runner.sh --resume
```

## Architecture

The build system implements a modular architecture:

1. **Unified Entry Point**: `runner.sh` handles platform selection, argument parsing, and environment checks.
2. **Orchestration**: `scripts/main-linux.sh` and `scripts/main-windows.sh` coordinate the dependency tree.
3. **Execution Primitives**: `scripts/function.sh` contains the core logic for downloading, configuring, and compiling generic C/C++ projects.
4. **Library Recipes**: `scripts/run-linux.sh` and `scripts/run-windows.sh` contain specific build instructions for 100+ libraries.

## Output Structure

Artifacts are generated in the `prebuilt/` directory.

```

## Build Phases

1. **Setup**: Initialize paths, environment variables (`CFLAGS`, `LDFLAGS`), and architecture settings.
2. **Toolchain**: Build or verify MinGW-w64 GCC 15+ toolchain (Windows targets only).
3. **Dependencies**: Compile enabled external libraries (e.g., x264, openssl, freetype) sequentially.
4. **FFmpeg**: Configure and build FFmpeg linking against the built dependencies.
5. **FFmpegKit**: Build the C++ wrapper library (`libffmpegkit`).
6. **Bundle**: Aggregate artifacts, fix paths in `pkg-config`, and collect licenses.

1. AI features are not supported on all platforms. You must deploy your own custom build of ffmpeg-kit-extended to enable certain AI features.
   - See [Supported External Libraries](https://github.com/akashskypatel/ffmpeg-kit-builders?tab=readme-ov-file#supported-external-libraries) for more information.

3. Platform features are built-in platform libraries that FFmpeg support like AVFounation, VideoToolbox, etc. on apple platforms or DirectX, MediaFoundation on Windows.

4. HTTPS features are enabled by default for Platforms that have built-in HTTPS support like Windows or Apple. For Linux and Android OpenSSL is enabled by default.

## Bundle Contents by Platform

Shows which bundle first includes each library on iOS, macOS, Android, Linux, and Windows.

### Filters

> **Windows**: `gfxcapture` is disabled due to MinGW compatibility issues.

### GPL licensing

> - Libraries marked [10](#gpl-info) are only compiled in when `--enable-gpl` is passed. Enabling any GPL library makes the resulting FFmpeg binary GPL-licensed and **non-redistributable under a permissive license**. Without `--enable-gpl`, those libraries are silently skipped even if their bundle is selected. The most impactful GPL libraries by bundle are:
> - **Audio+**: libbs2b, libcdio, librubberband, libjack *(Linux)*
> - **Video+**: libx264, libx265, libdavs2, libdvdnav, libdvdread, libxavs, libxavs2, libxvid *(Linux)*, frei0r, libvidstab
> - **Video+HW+**: v4l2-m2m *(Linux)*
> - **Video+ (Desktop only)**: avisynth

### AI

> **`libopenvino`**, and **`libtensorflow`** only available on Desktop builds (`MacOS`, `Linux`, and `Windows`). **`libtorch`** only available on `Linux` and `MacOs` builds (`Windows` not supported due ABI mismatch).

1 Platform specific libraries are enabled by default for target platform and bundle.<a id="platform-info"></a>
2 Extra libraries are enabled on non-small bundles.<a id="extra-info"></a>
3 RTMP(T)E support requires either gcrypt or gmp if the requires SSL library is not selected in the bundle.<a id="rtmpte-info"></a>
4 HTTPS feature in FFmpeg supports multiple SSL libraries. By default OpenSSL is selected unless you build a custom bundle with a specific supported library.<a id="https-info"></a>
5 MQ libraries are not enabled by default in any bundle. A custom build must be deployed to enable them using `--enable-mq` OR `--enable-librabbitmq` and `--enable-libzmq`.<a id="mq-info"></a>
6 SAMBA (SMB protocol) library is not enabled by default in any bundle (except on Windows, which supports SMB by default). A custom build must be deployed to enable them using `--enable-smb` OR `--enable-libsmbclient`.<a id="smb-info"></a>
7 SSH library is not enabled by default in any bundle. A custom build must be deployed to enable them using `--enable-ssh` OR `--enable-libssh`.<a id="ssh-info"></a>
8 These libraries cannot be built statically. If you deploy a static build with these libraries they will not be bundled with FFmpegKit wrapper bundle. The target system will need these libraries installed or running the wrapper may crash immediately. <a id="install-info"></a>
9 These libraries have restrictive licenses that may make the binaries non-redistributable, are not compatible with GPL and only included with `--enable-nonfree`.<a id="nonfree-info"></a>
10 These libraries are GPL and only included with `--enable-gpl`.<a id="gpl-info"></a>
11 These libraries can either be selected with GPU support or CPU only. Note that some of them do not support AMD ROCm framework. These libraries are not available on Mobile platforms due to platform limitations.<a id="compute-info"></a>
12 while these libraries are not compatible with GPL and have a more restrictive license, they are redistributable and will be bundled with non-gpl ffmpeg-kit bundle.<a id="redist-info"></a>
13 These libraries have been deprecated and will be auto-disabled and repalced by modern library if available.<a id="deprecated-info"></a>
14 These libraries conflict with other libraries with overlapping functionality. If both conflicting libraries are enabled, the preferred library, indicated by an * will be enabled and the other library will be disabled:<a id="conflict-info"></a>

> - libmfx -> libvpl*
> - libglslang -> libshaderc*

15 These libraries are only supported on specific CPU architectures.<a id="arch-info"></a>

> - libsvtjpegxs -> x86_64 only

## Troubleshooting

1. **WSL Issues**:
    - If using WSL, **WSL 2** is strongly recommended for build performance.
    - If cross-compiling, you may need to disable binfmt interop:

```bash
        sudo bash -c 'echo 0 > /proc/sys/fs/binfmt_misc/WSLInterop'
        ```

2. **Insufficient Memory**:
    - Linking static `libtensorflow` or `libtorch` requires significant RAM. If the build crashes during the final link step, increase swap space or allocated RAM to at least 8GB.
3. **Missing "Configure"**:
    - If a library fails because it cannot find `./configure`, ensure `autoconf`, `automake`, and `libtool` are installed. The script attempts to generate them via `autoreconf -fiv` if missing.
4. **Build Failures**:
    - Most of the dependencies are built from source and pinned to a spcific version to avoid failures due to code changes; however some are not. Since things are being built from source, there is always a chance that source changes could affect hard coded build parameters in the script. If you run into any build failures, its possible its because of this reason. Unfortunately this is unavoidable, so open an issue if you encounter any issues.
