booleanisRawFormat(javax.media.Format format)
MPEG video is not raw format. However, MonitorAdapter is only setting the render flag true for I frames on MPEG video so it can be treated as raw. Otherwise all frames must go to the decoder and the current decoder overloads the CPU.

	// If raw format, no need to decode just to keep state
	return ((format instanceof RGBFormat || format instanceof YUVFormat ||
		(format.getEncoding() != null &&
		(format.getEncoding().equalsIgnoreCase(VideoFormat.JPEG) ||
		format.getEncoding().equalsIgnoreCase(VideoFormat.MPEG)))));
