maybe something like the following pseudo patch would work?
- if(s->avctx->codec->id==CODEC_ID_AMV) {
+ if(s->flipped) {
//picture should be flipped upside-down for this codec
assert(!(s->avctx->flags & CODEC_FLAG_EMU_EDGE));
data[c] += (linesize[c] * (s->v_scount[i] * (8 * s->mb_height
-((s->height/s->v_max)&7)) - 1 ));
linesize[c] *= -1;
}
...
+if(some header indicates intels jpeg stuff ||
s->avctx->codec->id==CODEC_ID_AMV)
+ s->flipped=1;
