rlm@59 1 ======Capture Audio/Video to a File======
rlm@59 2
rlm@61 3 <note>A/V recording is still in development. It works for all of jMonkeyEngine's test cases. If you experience any problems or
rlm@61 4 of something isn't clear, please let me know. -- bortreb</note>
rlm@61 5
rlm@59 6 So you've made your cool new JMonkeyEngine3 game and you want to
rlm@59 7 create a demo video to show off your hard work. Or maybe you want to
rlm@59 8 make a cutscene for your game using the physics and characters in the
rlm@59 9 game itself. Screen capturing is the most straightforward way to do
rlm@59 10 this, but it can slow down your game and produce low-quality video and
rlm@59 11 audio as a result. A better way is to record video and audio directly
rlm@59 12 from the game while it is running.
rlm@59 13
rlm@61 14 <note tip>Combine this method with jMonkeyEngine's [[:jme3:advanced:Cinematics]] feature to record high-quality game trailers!</note>
rlm@60 15
rlm@60 16 ===== Simple Way =====
rlm@60 17
rlm@61 18 First off, if all you just want to record video at 30fps with no sound, then look
rlm@60 19 no further then jMonkeyEngine3's build in ''VideoRecorderAppState''
rlm@60 20 class.
rlm@60 21
rlm@61 22 Add the following code to your ''simpleInitApp()'' method.
rlm@60 23
rlm@60 24 <code java>
rlm@60 25 stateManager.attach(new VideoRecorderAppState()); //start recording
rlm@60 26 </code>
rlm@60 27
rlm@60 28 The game will run slow, but the recording will be in high-quality and
rlm@60 29 normal speed. The video files will be stored in your user home
rlm@60 30 directory, if you want to save to another file, specify it in the
rlm@60 31 VideoRecorderAppState constructor. Recording starts when the state is
rlm@60 32 attached and ends when the application quits or the state is detached.
rlm@60 33
rlm@60 34 That's all!
rlm@60 35
rlm@60 36 ===== Advanced Way =====
rlm@60 37
rlm@60 38 If you want to record audio as well, record at different framerates,
rlm@60 39 or record from multiple viewpoints at once, then there's a full
rlm@60 40 solution for doing this already made for you here:
rlm@59 41
rlm@59 42 http://www.aurellem.com/releases/jmeCapture-latest.zip
rlm@61 43
rlm@59 44 http://www.aurellem.com/releases/jmeCapture-latest.tar.bz2
rlm@59 45
rlm@59 46 Download the archive in your preferred format, extract,
rlm@59 47 add the jars to your project, and you are ready to go.
rlm@59 48
rlm@59 49 The javadoc is here:
rlm@59 50 http://www.aurellem.com/jmeCapture/docs/
rlm@59 51
rlm@60 52 To capture video and audio you use the
rlm@59 53 ''com.aurellem.capture.Capture'' class, which has two methods,
rlm@61 54 ''captureAudio()'' and ''captureVideo()'', and the
rlm@61 55 ''com.aurellem.capture.IsoTimer'' class, which sets the audio and
rlm@60 56 video framerate.
rlm@59 57
rlm@59 58 The steps are as simple as:
rlm@59 59
rlm@59 60 <code java>
rlm@59 61 yourApp.setTimer(new IsoTimer(desiredFramesPerSecond));
rlm@59 62 </code>
rlm@59 63
rlm@59 64 This causes jMonkeyEngine to take as much time as it needs to fully
rlm@59 65 calculate every frame of the video and audio. You will see your game
rlm@59 66 speed up and slow down depending on how computationally demanding your
rlm@59 67 game is, but the final recorded audio and video will be perfectly
rlm@59 68 sychronized and will run at exactly the fps which you specified.
rlm@59 69
rlm@59 70 <code java>
rlm@59 71 captureVideo(yourApp, targetVideoFile);
rlm@59 72 captureAudio(yourApp, targetAudioFile);
rlm@59 73 </code>
rlm@59 74
rlm@59 75 These will cause the app to record audio and video when it is run.
rlm@59 76 Audio and video will stop being recorded when the app stops. Your
rlm@59 77 audio will be recorded as a 44,100 Hz linear PCM wav file, while the
rlm@59 78 video will be recorded according to the following rules:
rlm@59 79
rlm@59 80 1.) (Preferred) If you supply an empty directory as the file, then
rlm@61 81 the video will be saved as a sequence of .png files, one file per
rlm@61 82 frame. The files start at 0000000.png and increment from there.
rlm@61 83 You can then combine the frames into your preferred
rlm@61 84 container/codec. If the directory is not empty, then writing
rlm@61 85 video frames to it will fail, and nothing will be written.
rlm@59 86
rlm@59 87 2.) If the filename ends in ".avi" then the frames will be encoded as
rlm@61 88 a RAW stream inside an AVI 1.0 container. The resulting file
rlm@61 89 will be quite large and you will probably want to re-encode it to
rlm@61 90 your preferred container/codec format. Be advised that some
rlm@61 91 video payers cannot process AVI with a RAW stream, and that AVI
rlm@61 92 1.0 files generated by this method that exceed 2.0GB are invalid
rlm@61 93 according to the AVI 1.0 spec (but many programs can still deal
rlm@61 94 with them.) Thanks to Werner Randelshofer for his excellent work
rlm@61 95 which made the AVI file writer option possible.
rlm@59 96
rlm@59 97 3.) Any non-directory file ending in anything other than ".avi" will
rlm@61 98 be processed through Xuggle. Xuggle provides the option to use
rlm@61 99 many codecs/containers, but you will have to install it on your
rlm@61 100 system yourself in order to use this option. Please visit
rlm@61 101 http://www.xuggle.com/ to learn how to do this.
rlm@59 102
rlm@60 103 Note that you will not hear any sound if you choose to record sound to
rlm@60 104 a file.

rlm@60 106 ==== Basic Example ====
rlm@60 107
rlm@60 108 Here is a complete example showing how to capture both audio and video
rlm@60 109 from one of jMonkeyEngine3's advanced demo applications.
rlm@60 110
rlm@60 111 <code java>
rlm@60 112 import java.io.File;
rlm@60 113 import java.io.IOException;

rlm@60 132 public static void main(String[] ignore) throws IOException{
rlm@60 133 File video = File.createTempFile("JME-water-video", ".avi");
rlm@60 134 File audio = File.createTempFile("JME-water-audio", ".wav");
rlm@60 135
rlm@60 136 SimpleApplication app = new TestPostWater();
rlm@60 137 app.setTimer(new IsoTimer(60));
rlm@60 138 app.setShowSettings(false);
rlm@60 139
rlm@60 140 Capture.captureVideo(app, video);
rlm@60 141 Capture.captureAudio(app, audio);
rlm@60 142
rlm@60 143 app.start();
rlm@60 144
rlm@60 145 System.out.println(video.getCanonicalPath());
rlm@60 146 System.out.println(audio.getCanonicalPath());
rlm@60 147 }
rlm@60 148 }
rlm@60 149 </code>
rlm@60 150
rlm@60 151 ==== How it works ====
rlm@60 152
rlm@61 153 A standard JME3 application that extends ''SimpleApplication'' or
rlm@61 154 ''Application'' tries as hard as it can to keep in sync with
rlm@61 155 //user-time//. If a ball is rolling at 1 game-mile per game-hour in the
rlm@60 156 game, and you wait for one user-hour as measured by the clock on your
rlm@60 157 wall, then the ball should have traveled exactly one game-mile. In
rlm@60 158 order to keep sync with the real world, the game throttles its physics
rlm@60 159 engine and graphics display. If the computations involved in running
rlm@60 160 the game are too intense, then the game will first skip frames, then
rlm@60 161 sacrifice physics accuracy. If there are particuraly demanding
rlm@60 162 computations, then you may only get 1 fps, and the ball may tunnel
rlm@60 163 through the floor or obstacles due to inaccurate physics simulation,
rlm@60 164 but after the end of one user-hour, that ball will have traveled one
rlm@60 165 game-mile.
rlm@60 166
rlm@60 167 When we're recording video, we don't care if the game-time syncs with
rlm@60 168 user-time, but instead whether the time in the recorded video
rlm@60 169 (video-time) syncs with user-time. To continue the analogy, if we
rlm@60 170 recorded the ball rolling at 1 game-mile per game-hour and watched the
rlm@60 171 video later, we would want to see 30 fps video of the ball rolling at
rlm@61 172 1 video-mile per //user-hour//. It doesn't matter how much user-time it
rlm@60 173 took to simulate that hour of game-time to make the high-quality
rlm@60 174 recording.
rlm@60 175
rlm@60 176 The IsoTimer ignores real-time and always reports that the same amount
rlm@60 177 of time has passed every time it is called. That way, one can put code
rlm@60 178 to write each video/audio frame to a file without worrying about that
rlm@60 179 code itself slowing down the game to the point where the recording
rlm@60 180 would be useless.
rlm@60 181
rlm@60 182
rlm@60 183 ==== Advanced Example ====
rlm@60 184
rlm@60 185 The package from aurellem.com was made for AI research and can do more
rlm@60 186 than just record a single stream of audio and video. You can use it
rlm@60 187 to:
rlm@60 188
rlm@60 189 1.) Create multiple independent listeners that each hear the world
rlm@60 190 from their own perspective.
rlm@60 191
rlm@60 192 2.) Process the sound data in any way you wish.
rlm@60 193
rlm@60 194 3.) Do the same for visual data.
rlm@60 195
rlm@60 196 Here is a more advanced example, which can also be found along with
rlm@60 197 other examples in the jmeCapture.jar file included in the
rlm@60 198 distribution.
