Usage

Maven:

<dependency>
  <groupId>net.bramp.ffmpeg</groupId>
  <artifactId>ffmpeg</artifactId>
  <version>0.4</version>
</dependency>

Code:

FFmpeg ffmpeg = new FFmpeg("/path/to/ffmpeg");
FFprobe ffprobe = new FFprobe("/path/to/ffprobe");

FFmpegBuilder builder = new FFmpegBuilder()

  .setInput("input.mp4")     // Filename, or a FFmpegProbeResult
  .overrideOutputFiles(true) // Override the output if it exists

  .addOutput("output.mp4")   // Filename for the destination
    .setFormat("mp4")        // Format is inferred from filename, or can be set
    .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(640, 480) // at 640x480 resolution

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

FFmpegExecutor executor = new FFmpegExecutor(ffmpeg, ffprobe);

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

// Or run a two-pass encode (which is slower at the cost of better quality)
executor.createTwoPassJob(builder).run();

Building & Releasing

If you wish to make changes, then building and releasing is simple:

# To build
mvn

# To test
mvn test

# To release (pushing jar to maven central)
mvn release:prepare
mvn release:perform

# To publish javadoc
mvn clean javadoc:aggregate scm-publish:publish-scm

Install FFmpeg on Ubuntu

We only the support the original FFmpeg, not the libav version. Before Ubuntu 12.04, and in 15.04 and later original FFmpeg is shipped. If you have to run on a version with libav, you can install FFmpeg from a PPA, or using the static build. More information here
