[Libav-user] Extract frames in raw RGB formats

[Amir Hossein Rouhi]

Hi Carl
What the bellow command line generate is a raw image but in YUV 4:2:0
format. what i want is RGB raw image. I know there is a formula to convert
YUV to RGB but i need pure RGB in the file. even i tried to use -pix_fmt
but could not find any parameter for RGB. Would you please give advice?
ffmpeg -i c:\foo.mp4 -r 1 -s 320x240 -vcodec rawvideo -pix_fmt uyvy422 -f
image2 c:\foo-%03d.rgb
