-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:
