| 27 : | * Application notes : | ||
| 28 : | chl | 119 | * |
| 29 : | * A sequence of YUV pics in PGM file format is encoded and decoded | ||
| 30 : | * The speed is measured and PSNR of decoded picture is calculated. | ||
| 31 : | * | ||
| 32 : | * The program is plain C and needs no libraries except for libxvidcore, | ||
| 33 : | edgomez | 483 | * and maths-lib. |
| 34 : | chl | 119 | * |
| 35 : | edgomez | 483 | * Usage : xvid_stat [OPTIONS] |
| 36 : | * Options : | ||
| 37 : | * -w integer : frame width ([1.2048]) | ||
| 38 : | * -h integer : frame height ([1.2048]) | ||
| 39 : | * -b integer : target bitrate (>0 | default=900kbit) | ||
| 40 : | * -f float : target framerate (>0) | ||
| 41 : | * -i string : input filename (default=stdin) | ||
| 42 : | * -t integer : input data type (yuv=0, pgm=1) | ||
| 43 : | * -n integer : number of frames to encode | ||
| 44 : | * -q integer : quality ([0..5]) | ||
| 45 : | * -d boolean : save decoder output (0 False*, !=0 True) | ||
| 46 : | * -m boolean : save mpeg4 raw stream (0 False*, !=0 True) | ||
| 47 : | edgomez | 548 | * -help : prints this help message |
| 48 : | edgomez | 483 | * -quant integer : fixed quantizer (disables -b setting) |
| 49 : | * (* means default) | ||
| 50 : | chl | 119 | * |
| 51 : | edgomez | 483 | * An input file named "stdin" is treated as standard input stream. |
| 52 : | chl | 119 | * |
| 53 : | * | ||
| 54 : | edgomez | 483 | * PGM input must be in a very specific format, basically it pgm file must |
| 55 : | * contain Y plane first just like usual P5 pgm files, and then U and V | ||
| 56 : | * planes are stored just after Y plane so y dimension is y*3/2 in reality | ||
| 57 : | * | ||
| 58 : | * See read_pgmheader for more details. | ||
| 59 : | * | ||
| 60 : | * Such a PGM file can be generated from MPEG2 by # mpeg2dec -o pgmpipe | ||
