![]() ![]() r represents frame rate of the output video Where the parameters present next to the following parameters To compress the above video in MPEG4 video formatįfmpeg -s:v 1280x720 -i input.yuv -vcodec mpeg4 -r 30 -pix_fmt yuv420p -b:v 5000k output.m4v To compress the YUV file of resolution 1280x720, frame rate 30 fps in H.264 video format at 5 Mbpsįfmpeg -s:v 1280x720 -i input.yuv -vcodec h264 -r 30 -pix_fmt yuv420p -b:v 5000k output.h264 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. For more details about FFMPEG please refer hereįor windows operating system, it is preferred to download the pre-built binary from here. Many open source media players are based on FFMPEG libraries.įFMPEG is developed under Linux but it can be compiled under most operating systems including Mac OS, Microsoft Windows. ![]() It is a free software project for manipulating/processing multimedia data. FFMPEG is a set of libraries and a command line tool for encoding and decoding audio and video in many different formats.
