Setup a new reference to the data described by a given packet
If src is reference-counted, setup dst as a new reference to the buffer in src. Otherwise allocate a new buffer in dst and copy the data from src into it.
All the other fields are copied from src.
@see av_packet_unref
@param dst Destination packet @param src Source packet
@return 0 on success, a negative AVERROR on error.
