9
10 The makefile should be setup for most UNIX systems as is. Simply type
11 "make" in the source code directory.
12
13 3) Testing the program.
14
15 A short test sequence is in short.p64 (and the coding is described in
16 short.trace). If you wish to extract image sequence files from
17 short.p64, type
18
19 p64 -d -s short.p64 short
20
21 The resulting files should be in
22
23 short0.Y, short0.U, short0.V
24 short1.Y, short1.U, short1.V
25 short2.Y, short2.U, short2.V
26 short3.Y, short3.U, short3.V
27 short4.Y, short4.U, short4.V
28 short5.Y, short5.U, short5.V
29 short6.Y, short6.U, short6.V
30
31 These files are raw raster-scan component files 352x240 for the Y,
32 176x120 for the U and V.
33
34 4) Displaying the decompressed files.
35
36 The decompressed *.Y *.U *.V files may be displayed through the
37 program "cv" which may be obtained by anonymous ftp from
38 havefun.stanford.edu:pub/cv/CVv1.1.tar.Z. If the program is in your
39 current directory search-path, type
40
41 cv -a 0 -b 6 short
42
43 If you wish to use CCIR-601 YUV->RGB colorspace conversion
44 (recommended for this sequence), use
45
46 cv -a 0 -b 6 short -C
47
48
49 5) Recompressing the short sequence files.
