OK, looks like ffmpeg can work with .rf directly.
I'm doing a simple

    ffmpeg -i input_file.rf output_file.mp4

and that seems to be working. I didn't find any info before hand on the 
filetypes that ffmpeg can work with, but it looks like .rf is OK.
Thanks for you consideration.
I am getting some "Invalid NAL unit size" errors and some "missing 
picture in access unit" errors, but it doesn't seem to be visibly 
affecting the output files.
I'll report if there's something that doesn't work.
