Define what do you mean by "join". Do you want to do alpha blending of one image on top of the other, or do you want to display them side-by-side? Both things should be possible with filters, for alpha blending you need a filter for changing the alpha values of the overlaied image, the second can be achieved with padding+overlay (but would be best achieved with a "compose" filter). _______________________________________________ libav-user mailing list [email protected] https://lists.mplayerhq.hu/mailman/listinfo/libav-user
