extension-ffmpeg

A Haxe library which provides support for handling video, audio, and multimedia files and streams on native platforms.

extension-ffmpeg boasts the following features:

• Decoding, display, and playback control for video and audio.
• Support for the most popular video formats, including avi, mp4, webm, flv, mkv, and more.
• Utilities for easy integration into OpenFL and HaxeFlixel.

Contributions are highly welcome! Feel free to open an issue or pull request if you have any questions or suggestions.

Building on Windows

To build extension-ffmpeg from source, perform these steps to fetch dependencies:

1. Do NOT download the repository by clicking the Download ZIP button on the Github page.

• Instead, run git clone https://github.com/MasterEric/extension-ffmpeg to create a local Git repository.

2. Install Visual Studio 2019, installing the following components:

• MSVC v142 - VS 2019 C++ x64/x86 build tools
• Windows SDK (10.0.17763.0)

3. Install MSYS2. I installed to the C:/CPP/msys64 directory.
4. Navigate to the project folder and call git submodule update --init --recursive --remote to download the source for FFmpeg.

Then, follow these steps:

1. Open x64 Native Tools Command Prompt for VS 2019 and call "C:\CPP\msys64\msys2_shell.cmd" -use-full-path.
2. Call pacman -Su git wget make tar unzip zip mingw-w64-x86_64-gcc mingw-w64-x86_64-gdb mingw-w64-x86_64-cmake autoconf automake libtool mingw-w64-x86_64-jq python zstd nasm (one-time step).
3. Navigate to the project folder, enter ./lib.src/, and run ./build_win64.sh to build the Windows64 library files.

Now, we need to build libraries for 32-bit machines.

• This is necessary because lime rebuild performs two builds, one for each architecture.

1. Open x86 Native Tools Command Prompt for VS 2019 and call "C:\CPP\msys64\msys2_shell.cmd" -use-full-path.
2. Navigate to the project folder, enter ./lib.src/ffmpeg, and run make clean.

• This gets rid of any artifacts from the previous 64-bit build.

4. Move back to ./lib.src/ and run build_win32.sh to build the Windows32 library files.

This will generate the necessary .lib files that you need to build the extension.

To build the extension itself, run lime rebuild extension-ffmpeg windows. You will need to repeat this step if you change any of the C++ files located in the project folder. Be sure to run lime rebuild extension-ffmpeg windows -debug instead if you are planning to debug the target application.

Building on Linux

To build extension-ffmpeg from source, follow these steps:

1. Do NOT download the repository by clicking the Download ZIP button on the Github page.

• Instead, run git clone https://github.com/MasterEric/extension-ffmpeg to create a local Git repository.

2. Install these development packages: libvdpau-dev libva-dev libx11-dev
3. Navigate to the project folder.
4. Call git submodule update --init --recursive --remote to download the source for FFmpeg.
5. Navigate to ./lib.src/.
6. Run ./build_linux64.sh.

• You will need to repeat this step if you modify the compile flags in the script (which are used to build FFmpeg's libs).

This will generate the necessary .a files that you need to build the extension.

To build the extension itself, run lime rebuild extension-ffmpeg linux. You will need to repeat this step if you change any of the C++ files located in the project folder. Be sure to run lime rebuild extension-ffmpeg linux -debug instead if you are planning to debug the target application.

Building on MacOS

To build extension-ffmpeg from source, follow these steps:

1. Do NOT download the repository by clicking the Download ZIP button on the Github page.

• Instead, run git clone https://github.com/MasterEric/extension-ffmpeg to create a local Git repository.

2. Use Brew to install dependencies:

• brew install nasm openssl

3. Navigate to the project folder.
4. Call git submodule update --init --recursive --remote to download the source for FFmpeg.
5. Navigate to ./lib.src/.
6. Run ./build_mac64.sh.

• You will need to repeat this step if you modify the compile flags in the script (which are used to build FFmpeg's libs).

This will generate the necessary .a files that you need to build the extension.

To build the extension itself, run lime rebuild extension-ffmpeg mac. You will need to repeat this step if you change any of the C++ files located in the project folder. Be sure to run lime rebuild extension-ffmpeg mac -debug instead if you are planning to debug the target application.

Building for android

To build extension-ffmpeg from source, follow these steps:

1. Download and unzip the android ndk (r23c)
2. Navigate to the project folder.
3. Call git submodule update --recursive to download the source for FFmpeg.
4. Navigate to ./lib.src/.
5. Change the ndk path in build_android64.sh to your ndk path,
6. Run ./build_android64.sh.

This will generate the necessary .a files that you need to build the extension.

To build the extension itself, run lime rebuild extension-ffmpeg android.

this is still on testing, only 64 bits is supported as of now

Building on Other Platforms

Support for other platforms (Android, iOS, HTML5 via emscripten) is in development.
