| 23 : | * Speed test routine for XviD using the XviD-API | ||
| 24 : | * (C) Christoph Lampert, 2002/08/17 | ||
| 25 : | * | ||
| 26 : | * A sequence of YUV pics in PGM or RAW file format is encoded and the | ||
| 27 : | * raw MPEG-4 stream is written to stdout. | ||
| 28 : | * The encoding speed of this is measured, too. | ||
| 29 : | * | ||
| 30 : | * The program is plain C and needs no libraries except for libxvidcore, | ||
| 31 : | * and maths-lib, so with UN*X you simply compile by | ||
| 32 : | * | ||
| 33 : | * gcc xvid_encraw.c -lxvidcore -lm -o xvid_encraw | ||
| 34 : | * | ||
| 35 : | * Run without or with illegal parameters, then PGM input input is read | ||
| 36 : | * from stdin. | ||
| 37 : | * | ||
| 38 : | * Parameters are: xvid_stat XDIM YDIM QUALITY BITRATE/QUANTIZER FRAMERATE | ||
| 39 : | * | ||
| 40 : | * if XDIM or YDIM are illegal (e.g. 0), they are ignored and input is | ||
| 41 : | * considered to be PGM. Otherwise (X and Y both greater than 0) raw YUV | ||
| 42 : | * is expected, as e.g. the standard MPEG test-files, like "foreman" | ||
| 43 : | * | ||
| 44 : | * 0 <= QUALITY <= 6 (default 5) | ||
| 45 : | * | ||
| 46 : | * BITRATE is in kbps (default 900), | ||
| 47 : | * if BITRATE<32, then value is taken is fixed QUANTIZER | ||
| 48 : | * | ||
| 49 : | * FRAMERATE is a float (with or without decimal dot), default is 25.00 | ||
| 50 : | * | ||
| 51 : | * input/output and m4v-output is saved, if corresponding flags are set | ||
| 52 : | * | ||
| 53 : | * PGM input must in a very specific format, see read_pgmheader | ||
| 54 : | * it can be generated e.g. from MPEG2 by mpeg2dec -o pgmpipe | ||
