If you want to resize to some other resolution change the width and height assigned to the parameter scale. The below command resizes the input YUV video of resolution 1920x1080 in YUV 4:2:0 format to 1280x720 YUV videoįfmpeg -s:v 1920x1080 -i input.yuv -vf scale=1280:720 -c:v rawvideo -pix_fmt yuv420p output.yuv Sample YUV sequences can be downloaded from here. Input video will be usually in YUV 4:2:0 chroma subsampled format. Inputs to the Image and Video Processing will be generally YUV files. The luma component already existed as the black-and-white signal, they added the UV signal to this as a solution. They needed a signal transmission method that was compatible with black-and-white TV being able to add color. YUV was invented when engineers wanted color television in a black and white infrastructure. There are lot of color spaces available like RGB, CMYK, HSV, YUV, CIELAB etc., The one that is widely used for video processing is YUV color space. For Linux operating system, we can either build from the source by following the instruction given here or can install on Ubuntu using the following command
It is preferred to download the static build.
