#7897: ffmpeg ignores -r parameter for image frames used for overlay

Summary of the bug:
I have a video file running at 2997/100 FPS to which I want to add an
overlay which is in the form of a sequence of bitmap files. I want each of
the input video frame to have a separate bitmap overlaid (as if I wanted
to overlay a frame counter).
However, the default frame rate for a sequence of images is 25 FPS, which
results in dropped or duplicated overlay images. Setting the desired
framerate by `-r` does not work. I tried both `-r 29.97` and `-r 2997/100`
to no avail. The console output says the `-r` parameter was parsed
correctly, but still default value is used.
How to reproduce:

}}}
I have omitted part of the console output as I think it is irrelevant.
Of course, the `-r` option works correctly when I want to assemble just
the bitmap images into a video.
