thanks， I have already tried the top size 1 and 10 before on the enconder, I assume you are talking about the encoder, as the decoder can not config the gop size, I think it's should be a bug of and encoder or decoder, because if I start the decoder before amf encoder, it's working fine， it is either because the encoder only encode the first I frame properly or the decoder can not recognize the I frame generated by amf encoder.
