use java-ffmpeg wrapper, or simply use java runtime to execute ffmpeg?

Question

I\'m pretty new to Java, need to write a program that listen to video conversion instructions and convert the video once an new instruction arrives (instructions is stored i

Answer 1

I wrote my own Java ffmpeg command line wrapper: Jaffree. It works with both ffprobe and ffmpeg and supports programmatic video production and consumption. Also it has in my opinion more convenient fluid API.

Here is an ffprobe usage example:

FFprobeResult result = FFprobe.atPath(BIN)
        .setInputPath(VIDEO_MP4)
        .setShowStreams(true)
        .setShowError(true)
        .execute();

if (result.getError() != null) {
    //TODO handle ffprobe error message
    return;
}

for (Stream stream : probe.getStreams().getStream()) {
    //TODO analyze stream data
}

ProgressListener listener = new ProgressListener() {
    @Override
    public void onProgress(FFmpegProgress progress) {
        //TODO handle progress data
    }
};

And this is for ffmpeg:

FFmpegResult result = FFmpeg.atPath(BIN)
        .addInput(Input.fromPath(VIDEO_MP4))
        .addOutput(Output.toPath(outputPath)
                .addCodec(null, "copy")
        )
        .setProgressListener(listener)
        .execute();

Also, as of Xuggler 3.3, Xuggler is LGPL meaning you don't need a commercial license.
