* As a special exception, the copyright holders of XviD give you |
37 |
|
* permission to link XviD with independent modules that communicate with |
38 |
|
* XviD solely through the VFW1.1 and DShow interfaces, regardless of the |

43 |
|
* combined work), being distributed under the terms of the GNU General |
44 |

* Public License plus this exception. An independent module is a module |
45 |
|
* which is not derived from or based on XviD. |

* 15.07.2002 fix a bug in B-frame decode at DIRECT mode |
* Note that people who make modified versions of XviD are not obligated |
48 |
* MinChen <chenm001@163.com> |
* to grant this special exception for their modified versions; it is |
49 |
* 10.07.2002 added BFRAMES_DEC_DEBUG support |
* their choice whether to do so. The GNU General Public License gives |
50 |
* Fix a little bug for low_delay flage |
* permission to release a modified version without this exception; this |
51 |
* MinChen <chenm001@163.com> |
* exception also makes it possible to release a modified version which |
52 |
* 28.06.2002 added basic resync support to iframe/pframe_decode() |
* carries forward this exception. |
|
* 22.06.2002 added primative N_VOP support |
|
|
* #define BFRAMES_DEC now enables Minchen's bframe decoder |
|
|
* 08.05.2002 add low_delay support for B_VOP decode |
|
|
* MinChen <chenm001@163.com> |
|
|
* 05.05.2002 fix some B-frame decode problem |
|
|
* 02.05.2002 add B-frame decode support(have some problem); |
|
|
* MinChen <chenm001@163.com> |
|
|
* 22.04.2002 add some B-frame decode support; chenm001 <chenm001@163.com> |
|
|
* 29.03.2002 interlacing fix - compensated block wasn't being used when |
|
|
* reconstructing blocks, thus artifacts |
|
|
* interlacing speedup - used transfers to re-interlace |
|
|
* interlaced decoding should be as fast as progressive now |
|
|
* 26.03.2002 interlacing support - moved transfers outside decode loop |
|
|
* 26.12.2001 decoder_mbinter: dequant/idct moved within if(coded) block |
|
|
* 22.12.2001 lock based interpolation |
|
