Always always always include the complete output of ffmpeg when asking
for
help. For one, we don't know what error you got.

I think you must tell FFmpeg the pixel format and the size of the input
image. If you would use JPG or PNG as input format, then FFmpeg would
detect these details automatically. But for RAW format FFmpeg can't know
the details.
I gave the pixel_format and input size is 1920x1080, but I get error width
is not set and one more error which I dont understand.
C:\Naveen\projects\DMS\software\ffmpeg_full\ffmpeg\bin>ffmpeg -pixel_format
gray10le -i CapturedImage-001.raw -r 30 -s 1920x1080
CapturedImageScale-001.raw
The -s option in your command line is for the output size because it's
written after -i.
You must also set the input size before -i.
Your RAW image contains only pixel data and no header for size and pixel
format.
