Today, the term YUV is commonly used in the computer industry to describe file-formats that are encoded using YCbCr. The Y′UV model defines a color space in terms of one luma (Y′) and two chrominance (UV) components. Conversion to/from RGB - Luminance/chrominance - Converting between Y. The color inside YUV images is split across different components. Matching the file extension name, they are named Y, U and V respectively. Brightness information are stored as Y, while U and V contain the color information. YUV files can be encoded in a variety of bit ranges, namely 12, 16 or 24 bits. ffmpeg supports a large number of YUV pixel formats (run ffmpeg -pix_fmts to see all). You can convert any input file to a YUV file with: ffmpeg -i.
This application allows you analyze raw image data, you can display memory dumps of frame buffers, video buffers and uncompressed video files. about color formats, take a look into the following places: FOURCC YUV pixel formats list. You can find all kinds of YUV files with different formats: here. Example Images Download: You can download the example images of all the suppoted formats in version 2. (All in qcif format, x). RGB format.
A YUV file is a video file encoded in the YUV format. It stores a sequence of YUV images as a single video file and may be saved in YUV , , rgb2yuv - Converts RGB to YUV save_yuvframe - Saves selected frame from yuv sequence to image file scale_seq - Scales YUV sequence seq_frames. 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; stores the brightness (luminance) as the Y value, and the color (chrominance) as U and V values. #endif. // read a raw yuv image file. // raw yuv files can be generated by ffmpeg, for example, using: // ffmpeg -i athermirestaurant.com -c:v rawvideo -pix_fmt yuvp athermirestaurant.com
