34 : | edgomez | 651 | * |
35 : | edgomez | 851 | * 05.10.2002 support for interpolated images in qpel mode - Isibaar |
36 : | * 01.05.2002 BFRAME image-based u,v interpolation | ||
37 : | * 22.04.2002 added some B-frame support | ||
38 : | * 14.04.2002 added image_dump_yuvpgm(), added image_mad() | ||
39 : | * XVID_CSP_USER input support | ||
40 : | * 09.04.2002 PSNR calculations - Isibaar | ||
41 : | * 06.04.2002 removed interlaced edging from U,V blocks (as per spec) | ||
42 : | * 26.03.2002 interlacing support (field-based edging in set_edges) | ||
43 : | * 26.01.2002 rgb555, rgb565 | ||
44 : | * 07.01.2001 commented u,v interpolation (not required for uv-block-based) | ||
45 : | * 23.12.2001 removed #ifdefs, added function pointers + init_common() | ||
46 : | * 22.12.2001 cpu #ifdefs | ||
47 : | * 19.12.2001 image_dump(); useful for debugging | ||
48 : | * 6.12.2001 inital version; (c)2001 peter ross <pross@cs.rmit.edu.au> | ||
