Ok, i realize what is your problem. The output file 
(test_dec.yuv, if you don't changed) is always of 112kb 
because in the config file encoder.cfg, the default 
settings are to code 2 frames, this is because your 
output. I suggest to take a closer look at this config 
file
and then set the codec to perform what you desire.
Best Regards
