The original link is dead. But this "new" version has very little value anyway, just 10 days younger and 2 important fixes are NOT included:
- FFMPEG 0.5 from 2009-Mar
- Theora encoding fix (was NOT fixed until 2009-Mar, no idea when if ever ...)

Sorry forgot them ... I had been having them for centuries in my "DOS" directory ... oops, look at this :clap:

Any chance to get this debug version included in next HX ?

excellent :clap: BUG of FFMPEG or MinGW

I see :crying:

BTW, source of DKRNL32 already has one funny hack preventing stupid apps or compilers to seek below ZERO, while DOS is too stupid too to reject such NO-GO's :crying: ... what compilers or apps are affected by this BUG ?

After having notoriously criticized DGJPP for garbage I/O and advertising MinGW in the past the time has come to have a look on MinGW now for possible garbage I/O activity ... but I need a debug version of DKRNL32 :-|
