Codec AVOption crf (Select the quality for constant quality mode) specified for
output file #0 (hi.avi) has not been used for any stream. The most likely reason
 is either wrong type (e.g. a video option with no video streams) or that it is
a private option of some encoder which was not actually used for any stream.
File 'hi.avi' already exists. Overwrite ? [y/N] y
