I'm trying but not working. Windows

try {
    FFprobe ffprobe = new FFprobe("d:\\Distr\\ffprobe.exe");
    FFmpeg ffmpeg = new FFmpeg("d:\\Distr\\ffmpeg.exe");

    FFmpegProbeResult probeResult = ffprobe.probe("d:\\11111\\lqCfwIbG1EU.mp4");
    FFmpegFormat format = probeResult.getFormat();
    
    FFmpegStream  stream = probeResult.getStreams().get(0);
    
    FFmpegBuilder builder = new FFmpegBuilder()
            .setInput("d:\\11111\\list.txt") 
            .setFormat("concat") 
            .addExtraArgs("-safe", "0")
            .overrideOutputFiles(true) // Override the output if it exists
            .addOutput("d:\\11111\\output.mp4") // Filename for the destination
            //.setTargetSize(250_000) // Aim for a 250KB file
            .disableSubtitle() // No subtiles

            .setAudioChannels(1) // Mono audio
            .setAudioCodec("aac") // using the aac codec
            .setAudioSampleRate(48_000) // at 48KHz
            .setAudioBitRate(32768) // at 32 kbit/s

            .setVideoCodec("libx264") // Video using x264
            .setVideoFrameRate(24, 1) // at 24 frames per second
            .setVideoResolution(1080, 720) // at 640x480 resolution

            .setStrict(FFmpegBuilder.Strict.EXPERIMENTAL) // Allow FFmpeg to use experimental specs
            .done();

        builder.setVerbosity(FFmpegBuilder.Verbosity.DEBUG);
    
    FFmpegExecutor executor = new FFmpegExecutor(ffmpeg, ffprobe);

    // Run a one-pass encode
    executor.createJob(builder).run();

    // Or run a two-pass encode (which is better quality at the cost of being slower)
    //executor.createTwoPassJob(builder).run();
    
} catch (Exception e) {
    System.err.println(e);
