Encoding and decoding work must be explicitly assigned to a GPU when using multiple GPUs in one system. ffmpeg -vsync 0 -c:v h264cuvid -i input.264 -vf 'fade,hwuploadcuda,scalenpp1280:720' -c:v h264nvenc output.264 Multi-GPU. %04d specifies the position of the characters representing a sequential number in each file name matched by the pattern. Finally, the image is scaled using scalenpp and encoded on the GPU. ![]() To maintain the aspect ratio, you also need to designate your video height. Your video width will therefore scale down to 1080 / 4 270 pixels. Here, your resized video will have a resolution of 480 x 320. regular YUV and full-scale/ JPEG YUV in FFmpeg (PIXFMTYUV420P vs. ffmpeg -i input.mp4 -vf scale480:-1 output.mp4. Replace input.mp4 with the name of your video and output_ with the name your output image files. 2020 YCbCr (YUV 422 from PS4 Video Output Test) Pixel Depth: - (assumed 12-bit). Use this command to extract the video to a png image sequence:įfmpeg -i input.mp4 -pix_fmt rgba output_%04d.png.Open a terminal and navigate to the folder containing the video.FFmpeg provides a convenient command-line solution for converting video to images. mjpeg, from 'video.m.jpeg': Duration: N/A, bitrate: N/A Stream 0:0: Video: mjpeg, yuvj422p(pc), 1280x720, 25 fps, 25 thr, 1200k thm, 25 thc Output 0.
