My > question is why "format=rgb24" is required I believe it was already explained why it really is required in this case. Also important to mention imo is that in general, the automatic pix_fmt conversion cannot always succeed, the system as a whole is not and cannot be clairvoyant. Therefore, for a sufficiently complex filter-chain, you have to force conversions with format because without it, the conversion decisions may be wrong (or at least not optimal).
