FFmpeg bug with a image that has a #ededed color
11 avril 2023, par Денис ВыхрыстюкI want to generate a video from images. When the pictures have a gray(#ededed) background then a strange error occurs, but when with other colors everything is good.


I will be grateful for any help.


I run the following commands :


./ffmpeg.exe -s 1080x1080 -framerate 1 -i ./scene0_%6d.png -crf 1 -c:v rawvideo -pix_fmt yuv420p ./result.yuv



./ffmpeg.exe -s 1080x1080 -framerate 1 -i ./result.yuv -c:v libx264 -crf 15 -preset veryslow -pix_fmt yuv420p -maxrate 900M -bufsize 12000k ./final.mp4



Result :


Error: Option framerate not found
