[Ffmpeg-user] problem in uyvy422 conversion

Hello, Im getting segmentation fault while converting a 420 planer yuv image to uyvy422 yuv format. What may be the possible error? ./ffmpeg -s 720x480 -f rawvideo -pix_fmt yuv420p -i tempete_720_480_420.yuv -s 720x480 -f rawvideo -pix_fmt uyvy422 tempete_720_480_uyvy422.yuv Thanks Mangesh
