[rtmpdump] Memory leak in rtmpdump.c

Hi, In rtmpdump.c around line 476 in Download() function there is return RD_SUCCESS; which does not free memory from "buffer" which is allocated at the start of the function and never used after that. This is most likely a minor issue, but I thought reporting it anyway as it can be fixed with a simple free() call (or by moving allocation where memory is actualy used). -- Reijo
