Minor changes had to be made librtmp/hashswf.c Changed lines 499, 500 to path = malloc(hpre.av_len + home.av_len + sizeof(DIRSEP "Documents/.swfinfo")); sprintf(path, "%s%s" DIRSEP "Documents/.swfinfo", hpre.av_val, home.av_val); This allows it to work within an iPhone Apps documents directory. I tried setting the Environment variables, but without success. Use the buildfat.sh script to build a binary library which will work in the simulator and iPhone To build with OpenSSL (needed for rtmpe) use the OpenSSL from my GitHub and change the buildfat.sh to link to the correct location. The Download Manager project shows how to use the library.
