| 33 : | * History: | ||
| 34 : | * | ||
| 35 : | * 01.05.2002 BFRAME image-based u,v interpolation | ||
| 36 : | * 22.04.2002 added some B-frame support | ||
| 37 : | * 14.04.2002 added image_dump_yuvpgm(), added image_mad() | ||
| 38 : | * XVID_CSP_USER input support | ||
| 39 : | * 09.04.2002 PSNR calculations | ||
| 40 : | * 06.04.2002 removed interlaced edging from U,V blocks (as per spec) | ||
| 41 : | * 26.03.2002 interlacing support (field-based edging in set_edges) | ||
| 42 : | * 26.01.2002 rgb555, rgb565 | ||
| 43 : | * 07.01.2001 commented u,v interpolation (not required for uv-block-based) | ||
| 44 : | * 23.12.2001 removed #ifdefs, added function pointers + init_common() | ||
| 45 : | * 22.12.2001 cpu #ifdefs | ||
| 46 : | * 19.12.2001 image_dump(); useful for debugging | ||
| 47 : | * 6.12.2001 inital version; (c)2001 peter ross <pross@cs.rmit.edu.au> | ||
