* ... ??? |
* 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 |
