| 26 : | suxen_drol | 295 | * 12.07.2002 num_threads |
| 27 : | suxen_drol | 235 | * 23.06.2002 XVID_CPU_CHKONLY; loading speed up |
| 28 : | suxen_drol | 137 | * 25.04.2002 ICDECOMPRESS_PREROLL |
| 29 : | h | 127 | * 17.04.2002 re-enabled lumi masking for 1st pass |
| 30 : | h | 121 | * 15.04.2002 updated cbr support |
| 31 : | h | 102 | * 04.04.2002 separated 2-pass code to 2pass.c |
| 32 : | * interlacing support | ||
| 33 : | * hinted ME support | ||
| 34 : | h | 61 | * 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 : | h | 30 | * 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 | ||
