Following comments of Paul B Mahol in another thread

Here too, data alignment "is made" with AVFrame->data / AVFrame->linesize

these func are call with this code :

c->utdsp.restore_rgb_planes(frame.f->data[2], frame.f->data[0],
frame.f->data[1],
                                    frame.f->linesize[2],
frame.f->linesize[0], frame.f->linesize[1],
                                    avctx->width, avctx->height);
and
c->utdsp.restore_rgb_planes10((uint16_t *)frame.f->data[2], (uint16_t
*)frame.f->data[0], (uint16_t *)frame.f->data[1],
                                      frame.f->linesize[2] / 2,
frame.f->linesize[0] / 2, frame.f->linesize[1] / 2,
                                      avctx->width, avctx->height);
