Lack of example files for -qpfile (sample_encode) and -roi_file (sample_multitranscode)

sample_encode:
[-qpfile ] - if specified, the encoder will take frame parameters (frame number, QP, frame type) from text file

sample_multi_transcode:
-roi_file
Set Regions of Interest for each frame from

I would say that example input files for these options may help user to move forward faster.
At that moment we analyze source code to see how parsers for these files work and this is not what we expect from test tool.
