24 : | * History: | ||
25 : | * | ||
26 : | * 12.07.2002 num_threads | ||
27 : | * 23.06.2002 XVID_CPU_CHKONLY; loading speed up | ||
28 : | * 25.04.2002 ICDECOMPRESS_PREROLL | ||
29 : | * 17.04.2002 re-enabled lumi masking for 1st pass | ||
30 : | * 15.04.2002 updated cbr support | ||
31 : | * 04.04.2002 separated 2-pass code to 2pass.c | ||
32 : | * interlacing support | ||
33 : | * hinted ME support | ||
34 : | * 23.03.2002 daniel smith <danielsmith@astroboymail.com> | ||
35 : | * changed inter4v to only be in modes 5 or 6 | ||
36 : | * fixed null mode crash ? | ||
37 : | * merged foxer's alternative 2-pass code | ||
38 : | * added DEBUGERR output on errors instead of returning | ||
39 : | * 16.03.2002 daniel smith <danielsmith@astroboymail.com> | ||
40 : | * changed BITMAPV4HEADER to BITMAPINFOHEADER | ||
41 : | * - prevents memcpy crash in compress_get_format() | ||
42 : | * credits are processed in external 2pass mode | ||
43 : | * motion search precision = 0 now effective in 2-pass | ||
44 : | * modulated quantization | ||
45 : | * added DX50 fourcc | ||
46 : | * 01.12.2001 inital version; (c)2001 peter ross <pross@xvid.org> | ||
