|
* 22.04.2002 add some B-frame decode support; chenm001 <chenm001@163.com> |
36 |
|
* 29.03.2002 interlacing fix - compensated block wasn't being used when |
37 |
|
* reconstructing blocks, thus artifacts |
38 |
|
* interlacing speedup - used transfers to re-interlace |
39 |
|
* interlaced decoding should be as fast as progressive now |
40 |
* 26.03.2002 interlacing support - moved transfers outside decode loop |
* 26.03.2002 interlacing support - moved transfers outside decode loop |
41 |
* 26.12.2001 decoder_mbinter: dequant/idct moved within if(coded) block |
