A little more info on this one:

Here is the code from the ff_copy_bits function from mpegvideo.c :
void ff_copy_bits(PutBitContext *pb, uint8_t *src, int length)
{
    const uint16_t *srcw= (uint16_t*)src;
    int words= length>>4;
    int bits= length&15;
    int i;

    if(length==0) return;

    if(words < 16){
        for(i=0; i<words; i++) put_bits(pb, 16, be2me_16(srcw[i]));
    }else if(put_bits_count(pb)&7){
        for(i=0; i<words; i++) put_bits(pb, 16, be2me_16(srcw[i]));
    }else{
        for(i=0; put_bits_count(pb)&31; i++)
            put_bits(pb, 8, src[i]);
        flush_put_bits(pb);
        memcpy(pbBufPtr(pb), src+i, 2*words-i);
        skip_put_bytes(pb, 2*words-i);
    }

    put_bits(pb, bits, be2me_16(srcw[words])>>(16-bits));

>From the compile output just before the error it looks as if the code is
compiling for generic i386?:

 Don't know if this could be part of the problem? "[build-arch-stamp]
would appear to corrobereate this.


If I do a #./configure --arch=k8  - #qmake mythtv.pro - #make, I also get
an error from libavcodec/:

I think I remember other apps (Mplayer for example) getting libavcodec
from ffmpeg.... should I be looking at recompiling this or re-installing
other dependencies?

Sorry to be so lost here.
