convertToFormat	back to summary
public VideoDataBuffer convertToFormat(VideoFormat newFormat) Implements com.sun.media.jfxmedia.control.VideoDataBuffer.convertToFormat. Doc from com.sun.media.jfxmedia.control.VideoDataBuffer.convertToFormat. Converts the video image to the specified format. You can only convert TO either `ARGB_PRE` or `BGRA_PRE`, converting to YCbCr is not supported here. Once a conversion is done, a reference to the converted buffer is retained so that future conversions do not need to be performed. Annotations @Override
