This a test sequence of 3 images with a cactus moving from right to |
| 12 |
|
left. It bzip2-compressed for size reason (half the size of a |
| 13 |
|
ZIP-file). Binaries of bunzip2 are available for all major OSes at |
| 14 |
|
http://sources.redhat.com/bzip2/ The original source of the cactus |
| 15 |
|
image is unknown... |

This is a small example that allows you to encode YUV streams or PGM |
| 21 |
|
files into a MPEG4 stream. It can output single files (on per encoded |
| 22 |
|
frame), or one file for all the enced stream (m4v format or a simple |
| 23 |
|
container format that we called mp4u, its description can be found at |
| 24 |
|
the end of this file). This program also outputs some very basic time |
| 25 |
|
results. |
| 26 |
|
|
| 27 |
|
Type "xvid_encraw -help" to have all options' description. |

|
Examples : |
| 30 |
|
|
| 31 |
|
1) bzip2 -dc cactus.pgm.bz2 | ./xvid_encraw -type 1 |
| 32 |
|
|
| 33 |
|
This command decompress cactus.pgm.bz2 and pipe the pgm file to |
| 34 |
|
xvid_encraw that will compress it to mpeg4 format. No mp4 stream |
| 35 |
|
output is written to disk. |
| 36 |
|
|
| 37 |
|
2) ./xvid_encraw -type 1 -i cactus.pgm -save |
| 38 |
|
|
| 39 |
|
Compress cactus.pgm frames into mpeg4 stream, and then writes a |
| 40 |
|
m4v file per encoded frame. |
| 41 |
|
|
| 42 |
|
3) ./xvid_encraw -type 1 -i cactus.pgm -o my_xvid_example.m4v -stats |
| 43 |
|
|
| 44 |
|
Same thing as above but saves all raw m4v data to a singlefile, |
| 45 |
|
and displays yuv-plane psnr statistics to stdout. |

|
|
| 51 |
|
This is a decoder example that is able to decode a m4v or mp4u |
| 52 |
|
stream. You can use it to decode what xvid_encraw encoded. |
| 53 |
|
|
| 54 |
|
Type "xvid_decraw -help" to have all options' description. |
| 55 |
|
|
| 56 |
|
Examples : |
| 57 |
|
|
| 58 |
* xvid_enc_dec.c |
1) ./xvid_decraw -i stream.m4v -d |
| 59 |
|
|
| 60 |
This is a complete example of the XviD-API for encoding and decoding: |
This command decodes a m4v file from stream.m4v and saves all |
| 61 |
The program reads a file of YUV 4:2:0 images (as greyscale picture in |
decoder output frames to individual PGM files (framexxxxx.pgm). |
|
PGM-format) and encodes this sequence to a MPEG4 bytestream. Then it |
|
|
decodes right away. |
|
| 62 |
|
|
| 63 |
* odivx_enc_dec.c |
2) cat stream.m4v | ./xvid_decraw |
| 64 |
|
|
| 65 |
Same program, but using the OpenDivX/DivX4 compatibility API. Wit this |
This examples decodes a m4v stream from standard input, but does |
| 66 |
you can use source written for DivX4 and simply relink with XviD-corelibrary. |
save any decoded frames. |
