MPEG Version 1.2 1) Printing documentation: Documentation is in the PostScript file doc.ps. It is about 50 pages long. 2) Making the program. The makefile should be setup for most UNIX systems as is. Simply type "make" in the source code directory. 3) Testing the program. A short test sequence is in short.mpg (and the coding is described in short.trace). If you wish to extract image sequence files from short.mpg, type mpeg -d -s short.mpg short The resulting files should be in short0.Y, short0.U, short0.V short1.Y, short1.U, short1.V short2.Y, short2.U, short2.V short3.Y, short3.U, short3.V short4.Y, short4.U, short4.V short5.Y, short5.U, short5.V short6.Y, short6.U, short6.V These files are raw raster-scan component files 352x240 for the Y, 176x120 for the U and V. 4) Displaying the decompressed files. The decompressed *.Y *.U *.V files may be displayed through the program "cv" which may be obtained by anonymous ftp from havefun.stanford.edu:pub/cv/CVv1.1.tar.Z. If the program is in your current directory search-path, type cv -a 0 -b 6 short 5) Recompressing the short sequence files. To use the default settings, and to put the output in short2.mpg, type mpeg -a 0 -b 6 short -s short2.mpg See the documentation for more details on other parameters. 6) Some short interpreted programs for the encoder: (See Chapter 4 of the documentation). test.intra test.pred test.rc test.pframe
