[Tom Jacobs]

hi

this is not about x264 directly but could anyone help me with padding the
1920x1080 files to 1088. i have tried the following in ffmpeg

ffmpeg -s 1920x1080 -f rawvideo -i rush_hour.yuv -padbottom 8 -o
rush_hour_pad.yuv

but i get
rush_hour.yuv: could not find codec parameters

as an error. if anyone know the correct command or another easy tool to do
it id be much appreciated
