From a generic AVI to a youtube-like FLV movie, with an embedded MP3 audio stream:

File source = new File("source.avi"); File target = new File("target.flv"); AudioAttributes audio = new AudioAttributes(); audio.setCodec("libmp3lame"); audio.setBitRate(new Integer(64000)); audio.setChannels(new Integer(1)); audio.setSamplingRate(new Integer(22050)); VideoAttributes video = new VideoAttributes(); video.setCodec("flv"); video.setBitRate(new Integer(160000)); video.setFrameRate(new Integer(15)); video.setSize(new VideoSize(400, 300)); EncodingAttributes attrs = new EncodingAttributes(); attrs.setFormat("flv"); attrs.setAudioAttributes(audio); attrs.setVideoAttributes(video); Encoder encoder = new Encoder(); encoder.encode(source, target, attrs);

Next lines extracts audio informations from an AVI and store them in a plain WAV file:

File source = new File("source.avi"); File target = new File("target.wav"); AudioAttributes audio = new AudioAttributes(); audio.setCodec("pcm_s16le"); EncodingAttributes attrs = new EncodingAttributes(); attrs.setFormat("wav"); attrs.setAudioAttributes(audio); Encoder encoder = new Encoder(); encoder.encode(source, target, attrs);

Next example takes an audio WAV file and generates a 128 kbit/s, stereo, 44100 Hz MP3 file:

File source = new File("source.wav"); File target = new File("target.mp3"); AudioAttributes audio = new AudioAttributes(); audio.setCodec("libmp3lame"); audio.setBitRate(new Integer(128000)); audio.setChannels(new Integer(2)); audio.setSamplingRate(new Integer(44100)); EncodingAttributes attrs = new EncodingAttributes(); attrs.setFormat("mp3"); attrs.setAudioAttributes(audio); Encoder encoder = new Encoder(); encoder.encode(source, target, attrs);

Next one decodes a generic AVI file and creates another one with the same video stream of the source and a re-encoded low quality MP3 audio stream:

File source = new File("source.avi"); File target = new File("target.avi"); AudioAttributes audio = new AudioAttributes(); audio.setCodec("libmp3lame"); audio.setBitRate(new Integer(56000)); audio.setChannels(new Integer(1)); audio.setSamplingRate(new Integer(22050)); VideoAttributes video = new VideoAttributes(); video.setCodec(VideoAttributes.DIRECT_STREAM_COPY); EncodingAttributes attrs = new EncodingAttributes(); attrs.setFormat("avi"); attrs.setAudioAttributes(audio); attrs.setVideoAttributes(video); Encoder encoder = new Encoder(); encoder.encode(source, target, attrs);

Next one generates an AVI with MPEG 4/DivX video and OGG Vorbis audio:

File source = new File("source.avi"); File target = new File("target.avi"); AudioAttributes audio = new AudioAttributes(); audio.setCodec("libvorbis"); VideoAttributes video = new VideoAttributes(); video.setCodec("mpeg4"); video.setTag("DIVX"); video.setBitRate(new Integer(160000)); video.setFrameRate(new Integer(30)); EncodingAttributes attrs = new EncodingAttributes(); attrs.setFormat("mpegvideo"); attrs.setAudioAttributes(audio); attrs.setVideoAttributes(video); Encoder encoder = new Encoder(); encoder.encode(source, target, attrs);

A smartphone suitable video:

File source = new File("source.avi"); File target = new File("target.3gp"); AudioAttributes audio = new AudioAttributes(); audio.setCodec("libfaac"); audio.setBitRate(new Integer(128000)); audio.setSamplingRate(new Integer(44100)); audio.setChannels(new Integer(2)); VideoAttributes video = new VideoAttributes(); video.setCodec("mpeg4"); video.setBitRate(new Integer(160000)); video.setFrameRate(new Integer(15)); video.setSize(new VideoSize(176, 144)); EncodingAttributes attrs = new EncodingAttributes(); attrs.setFormat("3gp"); attrs.setAudioAttributes(audio); attrs.setVideoAttributes(video); Encoder encoder = new Encoder(); encoder.encode(source, target, attrs);
