[MPlayer-users] Error in 64-bit compile - using 16-bit assembly instructions

[Jason Awuku]

I'm trying to compile the latest mplayer svn on Ubuntu Edgy 64-bit.
The compilation gets stuck at a c-file called osd.c:

Console Output:

I traced this back to the file libvo/osd_template.c

In this file, is the offending article at lines 417-445

#else /* HAVE_MMX */
    for(x=0;x<w;x++){
        if(srca[x]){
	    asm volatile(
		"movzbl (%0), %%ecx\n\t"
		"movzbl 1(%0), %%eax\n\t"
		"movzbl 2(%0), %%edx\n\t"

		"imull %1, %%ecx\n\t"
		"imull %1, %%eax\n\t"
		"imull %1, %%edx\n\t"

 		"addl %2, %%ecx\n\t"
		"addl %2, %%eax\n\t"
		"addl %2, %%edx\n\t"

		"movb %%ch, (%0)\n\t"
		"movb %%ah, 1(%0)\n\t"
		"movb %%dh, 2(%0)\n\t"

		:
		:"r" (&dstbase[4*x]),
		 "r" ((unsigned)srca[x]),
		 "r" (((unsigned)src[x])<<8)
		:"%eax", "%ecx", "%edx"
		);
            }
        }
#endif /* HAVE_MMX */

%ch, %dh and %ah registers are not used in x86_64.

Should I just comment out this section, or has somebody come up with a
patch already?

Thanks
