of course mplayer on 68k should be ported for the fastest Amiga Classic now, WinUAE e Amithlon.
Amithlon should be faster than WinUAE..
I have amiga source of mplayer send me by afxgroup (amigaos4 porting of mplayer) that he has compiled on winuae..
I have several problem to compile it.. on amithlon or with
AmiDevCPP
errors on "cpudetect.c"
