Does anybody know YUV:4:2:0 file format? I mean how a video is stored in a file with this format (in detail).
回答1:
YUV 4:2:0 isn't a file format its a video data format specifying the ratio between the Y, the U and the V components per pixel. You would typically store such data in a container format such as AVI or MOV.
Have a look at Wikipedia for a description of YUV. A file of YUV will just be a sequential collection of YUV frames.
回答2:
Here you can find scripts for manipulating YCbCr (also known as 'YUV') sequences.

Take a look at yuv_export.m and yuv_import.m to see how these files are stored.

YUV is a file extension for a raster graphics file often associated with the Color Space Pixel Format. YUV files contain bitmap image data stored in the YUV format, which splits color across Y, U, and V values. It stores the brightness (luminance) as the Y value, and the color (chrominance) as U and V values. YUV files can be opened and converted using xnView.
