Notice
FFmpeg4Java depends on FFmpeg library. See http://ffmpeg.org for details.
FFmpeg is used under the terms of GNU Lesser General Public License, version 2.1.
FFmpeg library is statically linked with FFmpeg4Java's JNI library
Generate JNI code
We use docker for generating JNI code.
Before you continue install docker on your system
Create base image:
sh create-image-base.sh
Create image for generating code:
sh create-image-java.sh
Run a container from the image:
sh run-image-java.sh
The Java code will be generated in directory:
build/com.nextbreakpoint.ffmpeg4java/src/main/java
The JNI code will be generated in file:
build/ffmpeg4java_wrap.c
Build library for MacOS
Download and install command line tools from Apple Developer Center.
Generate JNI code before compiling library for MacOS
Execute build script:
sh build-macos.sh
The native library will be created in directory:
build/com.nextbreakpoint.ffmpeg4java/src/main/resources/macos
Build library for Linux
We use docker for compiling Linux library.
Generate JNI code before compiling library for Linux
Create repository image:
sh create-image-repo.sh
Create image for building library:
sh create-image-linux.sh
Run a container from the image:
sh run-image-linux.sh
The native library will be created in directory:
build/com.nextbreakpoint.ffmpeg4java/src/main/resources/linux
Build library for Windows (cross-compilation)
We use docker for cross-compiling Windows library using Mingw-w64.
Generate JNI code before compiling library for Windows
Create repository image:
sh create-image-repo.sh
Create image for building library:
sh create-image-mingw64.sh
Run a container from the image:
sh run-image-mingw64.sh
The native library will be created in directory:
build/com.nextbreakpoint.ffmpeg4java/src/main/resources/win32
Create and install artifacts
We use Apache Maven to compile and package the artifacts.
Generate JNI code and build libraries before creating artifacts
Create artifacts:
sh mvn-package.sh
The artifacts will be created in directory:
build/com.nextbreakpoint.ffmpeg4java/target
Install artifacts:
sh mvn-install.sh
The artifacts will be installed in local maven repository (~/.m2/repository).
Run tests
We use Apache Maven to run the tests.
Install artifacts in local repository before running tests
Run tests on MacOS:
sh run-tests.sh -Pmacos
Run tests on Linux:
sh run-tests.sh -Plinux
Run tests on Windows:
sh run-tests.sh -Pwin32
TODO
- Add sample application to show how to use the library
