'Unsupported frame rate' produced for -r of fractional / non int values about ffmbc HOT 5 CLOSED

10 fps is not supported like the process says. I'm not sure what should be 
written to be more clear.
Btw ffmpeg output is not wanted when reporting bugs, output of ffmbc is 
required however.

Well 0.10 fps or other wierd values.

The error is clear, its just that the documentation suggests -r accepts 
fractional values, and the functionality is 
useful for producing thumbnails from video streams.  Is it the intention that 
this functionality is to be dropped 
from FFmbc ?

Well, I don't really have interest in supporting it currently, this is some 
burden, and not really broadcast oriented.
Was that working in previous ffmbc versions ?

I've only tried the command against FFmbc 0.3 & 0.4rc1, but can try against 
older versions if desired.

Im just embarking on a little project to create a transcode manager front end, 
like digital rapids - transcode 
manager / Rhozet carbon server style for FFmpeg/FFmbc.  With the intention 
being to create an open source 
tool to build scaleable transcode farms.  The big benefit with using FFmbc was 
the range of broadcast centric 
formats it currently supports, allowing native format export from an edit 
environment.

The fractional frame support would have made thumbnail generation much simpler, 
until I can teach myself 
sufficient C to write some kind of scene detect mechanism to generate proper 
keyframes.
