29 : | edgomez | 547 | * Application notes : |
30 : | chl | 376 | * |
31 : | edgomez | 547 | * An MPEG-4 bitstream is read from an input file (or stdin) and decoded, |
32 : | * the speed for this is measured. | ||
33 : | edgomez | 1382 | * |
34 : | * The program is plain C and needs no libraries except for libxvidcore, | ||
35 : | * and maths-lib. | ||
36 : | chl | 376 | * |
37 : | edgomez | 1382 | * Use ./xvid_decraw -help for a list of options |
