How to use the ffmpeg plugin in Android?

To use the FFmpeg plugin on Android, the following steps need to be taken:

1. You can download the FFmpeg library files from the official website (https://ffmpeg.org/download.html) or other sources.
2. Add the FFmpeg library files to the jniLibs directory in your Android project. If the directory does not exist, you can create it manually.
3. Add the following code to the build.gradle file in your Android project.

android {
    // ...
    sourceSets {
        main {
            jniLibs.srcDirs = ['jniLibs']
        }
    }
}

1. Call FFmpeg commands in the Activity or Fragment where FFmpeg is needed.

private void executeFFmpegCommand(String[] command) {
    FFmpeg ffmpeg = FFmpeg.getInstance(context);
    try {
        ffmpeg.execute(command, new ExecuteBinaryResponseHandler() {
            @Override
            public void onSuccess(String message) {
                // 处理成功的回调
            }

            @Override
            public void onFailure(String message) {
                // 处理失败的回调
            }
        });
    } catch (FFmpegCommandAlreadyRunningException e) {
        // 处理异常
    }
}

1. Build and execute FFmpeg command. For example, to convert a video file into a GIF file, you can use the following command:

String[] command = {"-i", "/path/to/input/video.mp4", "-vf", "fps=10,scale=320:-1:flags=lanczos", "/path/to/output/animation.gif"};
executeFFmpegCommand(command);

This allows you to use the FFmpeg plugin in Android. Please note that there is a learning curve when using FFmpeg, and specific command parameters and usage may need to be adjusted based on the context.
