If avctx->height is by default 0, then it would have to be something a la:

if (!avctx->height || avctx->height > 576) {
    YUV_TO_RGB1_CCIR_BT709(cb, cr);
} else {
    YUV_TO_RGB1_CCIR(cb, cr);

I guess? If the default is -1 then it'd be a check for <0 or >576.
This way even if in a cut file a palette comes up before a
presentation segment it should default to BT.709.
