public class JPEGRenderer
extends AbstractVideoRenderer
implements VideoRenderer

Renderer which renders JPEG directly. There is a comparable class in JMF, hence this implementation. However, it seems like this is not really needed if there is a JPEGDecoder Codec registered. However, the original cross-platform JMF did not include such a Codec. Because this class does not use BufferToImage, it is not subject to any of its limitations and will render images that BufferToImage does not support yet. This is not really anything good, it is only worth pointing out because it can be confusing when testing JPEG playback.
