Binary package “librtmp1” in ubuntu bionic

toolkit for RTMP streams (shared library)

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