I am sorry but I am unable to test with the ffmpeg application. I am 
receiving the frames from an embedded equipment with a propietary 
protocol. My app is decoding this frames, taking the h264 raw data and 
send them to the libavcodec. I set up a timing system to see which part 
is consuming the time, and it seems that it stays in libavcodec  
avcodec_decode_video2 function ~75 % from the total time and ~15 % in 
sws_scale function
