Description

The new decoder decodes correctly 32bpp interlaced mode (pal/ntsc), but fails with 24bpp.

I have also uploaded 32bpp progressive sample (which decodes incorrectly) and 24bpp progressive (which fails to decode.

progressive vs interlaced can be identified by mareked value (see mer.jpg)

01 - progressive
02 - interlaced

comment:5 Changed 5 years ago by ami_stuff

int 576 vs int 486 should be probably identified only by height, because this codec doesn't support custom sizes
