* A sequence of YUV pics in PGM or RAW file format is encoded and the |
* A sequence of raw YUV I420 pics or YUV I420 PGM file format is encoded |
| 30 |
* raw MPEG-4 stream is written to stdout. |
* The speed is measured and frames' PSNR are taken from core. |
|
* The encoding speed of this is measured, too. |
|
| 31 |
* |
* |
| 32 |
* The program is plain C and needs no libraries except for libxvidcore, |
* The program is plain C and needs no libraries except for libxvidcore, |
| 33 |
* and maths-lib, so with UN*X you simply compile by |
* and maths-lib. |
|
* |
|
|
* gcc xvid_encraw.c -lxvidcore -lm -o xvid_encraw |
|
|
* |
|
|
* Run without or with illegal parameters, then PGM input input is read |
|
|
* from stdin. |
|
|
* |
|
|
* Parameters are: xvid_stat XDIM YDIM QUALITY BITRATE/QUANTIZER FRAMERATE |
|
|
* |
|
|
* if XDIM or YDIM are illegal (e.g. 0), they are ignored and input is |
|
|
* considered to be PGM. Otherwise (X and Y both greater than 0) raw YUV |
|
|
* is expected, as e.g. the standard MPEG test-files, like "foreman" |
|
|
* |
|
|
* 0 <= QUALITY <= 6 (default 5) |
|
|
* |
|
|
* BITRATE is in kbps (default 900), |
|
|
* if BITRATE<32, then value is taken is fixed QUANTIZER |
|
|
* |
|
|
* FRAMERATE is a float (with or without decimal dot), default is 25.00 |
|
|
* |
|
|
* input/output and m4v-output is saved, if corresponding flags are set |
|
|
* |
|
|
* PGM input must in a very specific format, see read_pgmheader |
|
|
* it can be generated e.g. from MPEG2 by mpeg2dec -o pgmpipe |
