There is no limitation of one GOB per packet. The limitation is that a
GOB will not break between packets unless the macro block is longer then
the MTU, in that case you can break the GOB. There is no specific
structure for a packet with more then one GOB, it is as defined in
H.261. The only important information is that all packets of the same
frame will have the same time stamp.
