Here is one test method which checks that the encoder's view of decoded pictures in the same as the decoder's view. This ensures that there is no distortion besides what is inherently caused by compression. # Install and compile x264 : git clone git://git.videolan.org/x264.git x264 cd x264 ./configure make cd .. # Install and compile JM reference decoder : wget http://iphome.hhi.de/suehring/tml/download/jm17.2.zip unzip jm17.2.zip cd JM sh unixprep.sh cd ldecod make cd ../.. ./x264/x264 input.yuv --dump-yuv fdec.yuv -o output.h264 ./JM/bin/ldecod.exe -i output.h264 -o ref.yuv diff ref.yuv fdec.yuv
