/**
* SECTION:element-rtmpsrc
*
* This plugin reads data from a local or remote location specified
* by an URI. This location can be specified using any protocol supported by
* the RTMP library. Common protocols are 'file', 'http', 'ftp', or 'smb'.
*
* In case the #GstRTMPSrc:iradio-mode property is set and the
* location is a http resource, rtmpsrc will send special icecast http
* headers to the server to request additional icecast metainformation. If
* the server is not an icecast server, it will display the same behaviour
* as if the #GstRTMPSrc:iradio-mode property was not set. However,
* if the server is in fact an icecast server, rtmpsrc will output
* data with a media type of application/x-icy, in which case you will
* need to use the #GstICYDemux element as follow-up element to extract
* the icecast meta data and to determine the underlying media type.
*
* <refsect2>
* <title>Example launch lines</title>
* |[
* gst-launch -v rtmpsrc location=file:///home/joe/foo.xyz ! fakesink
* ]| The above pipeline will simply read a local file and do nothing with the
* data read. Instead of rtmpsrc, we could just as well have used the
* filesrc element here.
* |[
* gst-launch -v rtmpsrc location=smb://othercomputer/foo.xyz ! filesink location=/home/joe/foo.xyz
* ]| The above pipeline will copy a file from a remote host to the local file
* system using the Samba protocol.
* |[
* gst-launch -v rtmpsrc location=http://music.foobar.com/demo.mp3 ! mad ! audioconvert ! audioresample ! alsasink
* ]| The above pipeline will read and decode and play an mp3 file from a
* web server using the http protocol.
