The Sws_scale in FFmpeg is often used for image scaling and format conversion, and the function can use a variety of different algorithms to process the image. Used to be lazy, lazy to test and identify which algorithm should be used, the most recent work time, many times need to wait for others. Sneak in, the ffmpeg of this set of functions were encapsulated, by the way, testing a variety of algorithms. Br
