-jMonkeyEngine supports Jheora Ogg video (`com.jme3.video`).
|
|
|
-
|
|
|
-You create either a file inputstream to load the video from your hard drive:
|
|
|
-
|
|
|
-[source,java]
|
|
|
-----
|
|
|
-FileInputStream fis = new FileInputStream("E:\\my_bunny.ogg");
|
|
|
-----
|
|
|
-
|
|
|
-Or you stream the video live from a web location:
|
|
|
-
|
|
|
-[source,java]
|
|
|
-----
|
|
|
-InputStream fis = new URL("http://server/my_video.ogg").openStream();
|
|
|
-----
|
|
|
-
|
|
|
-Setting the queued frames to a value value higher than 5 (`videoQueue = new VQueue(5);`) will make web streamed playback smoother at the cost of memory.
|
|
|
-Here is an example of video streaming in context:
|
|
|
-
|
|
|
-[source,java]

|
|
|

|
|
|
- InputStream fis = new URL("http://mirrorblender.top-ix.org/peach/"+
|
|
|
- "bigbuckbunny_movies/big_buck_bunny_480p_stereo.ogg").openStream();
|
|
|
- videoQueue = new VQueue(5); // streaming quality vs memory
|
|
|
- decoder = new AVThread(fis, videoQueue);
|
|
|
- videoThread = new Thread(decoder, "Jheora Video Decoder");
|
|
|
- videoThread.setDaemon(true);
|
|
|
- videoThread.start();
|
|
|
