i'd say it's a bug anyway you look at it.
either it's a documentation bug,
as the doc describes a feature not available:
* To force the frame rate of the input and output file to 24 fps:
ffmpeg -r 24 -i input.avi output.avi
* To force the frame rate of input file to 1 fps and the output file to 24 fps:
ffmpeg -r 1 -i input.avi -r 24 output.avi
or it's a program bug, as a described feature is non operational.
ffmpeg -r 1 -i input.avi -y out.avi
