 A small dumper for media content streamed over the RTMP protocol (like BBC's
 iPlayer high quality streams). Supplying an rtmp URL will result in a dumped
 flv file, which can be played/transcoded using ffmpeg/mplayer, etc.

 This package contains the shared libraries, header files needed by
 programs that want to use librtmp.
