| 2 : | | XviD core lib examples | | ||
| 3 : | +--------------------------------------------------------------------+ | ||
| 4 : | |||
| 5 : | Isibaar | 3 | In this directory can find some examples how to use XviD MPEG4 codec |
| 6 : | in your own programs. | ||
| 7 : | |||
| 8 : | edgomez | 562 | ** cactus.pgm.bz2 |
| 9 : | ---------------------------------------------------------------------- | ||
| 10 : | Isibaar | 3 | |
| 11 : | edgomez | 562 | 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... | ||

| 18 : | ---------------------------------------------------------------------- | ||
| 19 : | Isibaar | 3 | |
| 20 : | edgomez | 562 | 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. | ||

| 27 : | edgomez | 562 | Type "xvid_encraw -help" to have all options' description. |

| 29 : | edgomez | 562 | Examples : |
| 30 : | Isibaar | 3 | |
| 31 : | suxen_drol | 1637 | 1) bzip2 -dc cactus.pgm.bz2 | ./xvid_encraw -type 1 |
| 32 : | Isibaar | 3 | |
| 33 : | suxen_drol | 1637 | 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 : | Isibaar | 3 | |
| 37 : | suxen_drol | 1637 | 2) ./xvid_encraw -type 1 -i cactus.pgm -save |
| 38 : | Isibaar | 3 | |
| 39 : | suxen_drol | 1637 | Compress cactus.pgm frames into mpeg4 stream, and then writes a |
| 40 : | m4v file per encoded frame. | ||
| 41 : | Isibaar | 3 | |
| 42 : | suxen_drol | 1637 | 3) ./xvid_encraw -type 1 -i cactus.pgm -o my_xvid_example.m4v -stats |
| 43 : | Isibaar | 3 | |
| 44 : | suxen_drol | 1637 | Same thing as above but saves all raw m4v data to a singlefile, |
| 45 : | and displays yuv-plane psnr statistics to stdout. | ||
| 46 : | edgomez | 562 | |
| 47 : | |||
| 48 : | ** xvid_decraw.c | ||
| 49 : | ---------------------------------------------------------------------- | ||
| 50 : | |||
| 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 : | suxen_drol | 1637 | 1) ./xvid_decraw -i stream.m4v -d |
| 59 : | edgomez | 562 | |
| 60 : | suxen_drol | 1637 | This command decodes a m4v file from stream.m4v and saves all |
| 61 : | decoder output frames to individual PGM files (framexxxxx.pgm). | ||
| 62 : | edgomez | 562 | |
| 63 : | suxen_drol | 1637 | 2) cat stream.m4v | ./xvid_decraw |
| 64 : | edgomez | 562 | |
| 65 : | suxen_drol | 1637 | This examples decodes a m4v stream from standard input, but does |
| 66 : | save any decoded frames. | ||
| 67 : | edgomez | 562 | |
| 68 : | |||
| 69 : | suxen_drol | 1637 | ** xvid_bench.c |
| 70 : | edgomez | 562 | ---------------------------------------------------------------------- |
| 71 : | |||
| 72 : | suxen_drol | 1637 | This is a tool to conduct unit testing and profiling of the signal |
| 73 : | processing functions used internally within libxvidcore. | ||
