| 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 : |
| svn co svn://svn.videolan.org/x264/trunk x264 |
| cd x264 |
| ./configure |
| perl -pi -e 's|//(#define DEBUG_DUMP_FRAME)|$1|' encoder/encoder.c # define DEBUG_DUMP_FRAME |
| make |
| cd .. |

| # Install and compile JM reference decoder : |
| wget http://iphome.hhi.de/suehring/tml/download/jm10.2.zip |
| unzip jm10.2.zip |
| cd JM |
| sh unixprep.sh |
| cd ldecod |
| make |
| cd ../.. |
| |
| ./x264/x264 input.yuv -o output.h264 # this produces fdec.yuv |
| ./JM/bin/ldecod.exe -i output.h264 -o ref.yuv |
| diff ref.yuv fdec.yuv |
