24 : | * History: | ||
25 : | * | ||
26 : | h | 121 | * 15.04.2002 updated cbr support |
27 : | h | 102 | * 04.04.2002 separated 2-pass code to 2pass.c |
28 : | * interlacing support | ||
29 : | * hinted ME support | ||
30 : | h | 61 | * 23.03.2002 daniel smith <danielsmith@astroboymail.com> |
31 : | * changed inter4v to only be in modes 5 or 6 | ||
32 : | * fixed null mode crash ? | ||
33 : | * merged foxer's alternative 2-pass code | ||
34 : | * added DEBUGERR output on errors instead of returning | ||
35 : | h | 30 | * 16.03.2002 daniel smith <danielsmith@astroboymail.com> |
36 : | * changed BITMAPV4HEADER to BITMAPINFOHEADER | ||
37 : | * - prevents memcpy crash in compress_get_format() | ||
38 : | * credits are processed in external 2pass mode | ||
39 : | * motion search precision = 0 now effective in 2-pass | ||
40 : | * modulated quantization | ||
41 : | * added DX50 fourcc | ||
42 : | Isibaar | 3 | * 01.12.2001 inital version; (c)2001 peter ross <suxen_drol@hotmail.com> |
