Memory Leak problem

I use this wrapper to download the packets from my RTMP server, though it is out of its original purpose(this wrapper is to send/write data to RTMP servers). Anyway, there is some memory leak in RTMP_ClientPacket, RTMP_Read. After I change rtmp.c with that in the 'RTMPdump', everythings are fixed. I think [rtmp.c in rtmp-wrapper] is not the same with [rtmp.c in RTMPdump].
