详细说明: YUV / RGB Format Selection: Whether you are going to use YUVPlayer, YUVConvertor, YUVAnalyser or YUVEditor, you need to load or save YUV files, and need to specify the right YUV format. When you select a file to read or write, a YUV format selection dialog will pop up, to help you to pick up a right YUV format. Writing a YUV file will be relatively easier than reading one. Since you can choose whatever format (as long as it is valid) format to write. On the other hand, to read a YUV file, you need to specify its data format: whether it is in 4:4:4, 4:2:2 or 4:2:0 sampling format, whether it has one single progressive frame or two interlaced fields, whether its pixel is packed or in planar format. If you do not know the format, this dialog will provide a help for you to guess one. Whenever a format is selected, three pictures will be displayed. The first one is the preview image, which is a scaled image of the first YUV frame. If you see a right colorful and meaningful image, you have selected the right format. The second is the diagram illustration of the data structure, to help you understand the internal data organization inside the file. The third one is the data dump of the file, which is the data display byte by byte (scaled). It provides you a "global view" of the data inside the file, and can be useful for you to guess what's the right format. ...展开收缩
