28 : | edgomez | 1.2 | * Application notes : |
29 : | chl | 1.1 | * |
30 : | edgomez | 1.2 | * An MPEG-4 bitstream is read from an input file (or stdin) and decoded, |
31 : | * the speed for this is measured. | ||
32 : | chl | 1.1 | * |
33 : | * The program is plain C and needs no libraries except for libxvidcore, | ||
34 : | * and maths-lib, so with UN*X you simply compile by | ||
35 : | edgomez | 1.2 | * |
36 : | chl | 1.1 | * gcc xvid_decraw.c -lxvidcore -lm -o xvid_decraw |
37 : | * | ||
38 : | * You have to specify the image dimensions (until the add the feature | ||
39 : | * to read this from the bitstream) | ||
40 : | edgomez | 1.2 | * |
41 : | * Usage : xvid_decraw <-w width> <-h height> [OPTIONS] | ||
42 : | * Options : | ||
43 : | * -asm : use assembly optimizations (default=disabled) | ||
44 : | * -w integer : frame width ([1.2048]) | ||
45 : | * -h integer : frame height ([1.2048]) | ||
46 : | * -i string : input filename (default=stdin) | ||
47 : | * -t integer : input data type (raw=0, mp4u=1) | ||
48 : | * -d boolean : save decoder output (0 False*, !=0 True) | ||
49 : | * -m boolean : save mpeg4 raw stream to single files (0 False*, !=0 True) | ||
50 : | * -help : This help message | ||
51 : | * (* means default) | ||
