+/**
+ * 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

+from http://jira.red5.org/confluence/display/docs/Ping:
+
+Ping is the most mysterious message in RTMP and till now we haven't fully interpreted it yet. In summary, Ping message is used as a special command that are exchanged between client and server. This page aims to document all known Ping messages. Expect the list to grow.
+
+The type of Ping packet is 0x4 and contains two mandatory parameters and two optional parameters. The first parameter is the type of Ping and in short integer. The second parameter is the target of the ping. As Ping is always sent in Channel 2 (control channel) and the target object in RTMP header is always 0 which means the Connection object, it's necessary to put an extra parameter to indicate the exact target object the Ping is sent to. The second parameter takes this responsibility. The value has the same meaning as the target object field in RTMP header. (The second value could also be used as other purposes, like RTT Ping/Pong. It is used as the timestamp.) The third and fourth parameters are optional and could be looked upon as the parameter of the Ping packet. Below is an unexhausted list of Ping messages.
+
+ * type 0: Clear the stream. No third and fourth parameters. The second parameter could be 0. After the connection is established, a Ping 0,0 will be sent from server to client. The message will also be sent to client on the start of Play and in response of a Seek or Pause/Resume request. This Ping tells client to re-calibrate the clock with the timestamp of the next packet server sends.
+ * type 1: Tell the stream to clear the playing buffer.
+ * type 3: Buffer time of the client. The third parameter is the buffer time in millisecond.
+ * type 4: Reset a stream. Used together with type 0 in the case of VOD. Often sent before type 0.
+ * type 6: Ping the client from server. The second parameter is the current time.
+ * type 7: Pong reply from client. The second parameter is the time the server sent with his ping request.
+ * type 26: SWFVerification request
+ * type 27: SWFVerification response

+ * The server meters its output so that data arrives at the client
+ * in realtime and no faster.
+ *
+ * The rtmpdump program tries to set m_nBufferMS as large as
+ * possible, to force the server to send data as fast as possible.
+ * In practice, the server appears to cap this at about 1 hour's
+ * worth of data. After the server has sent a complete buffer, and
+ * sends this BufferEmpty message, it will wait until the play
+ * duration of that buffer has passed before sending a new buffer.
+ * The BufferReady message will be sent when the new buffer starts.
+ * (There is no BufferReady message for the very first buffer;
+ * presumably the Stream Begin message is sufficient for that
+ * purpose.)
+ *
+ * If the network speed is much faster than the data bitrate, then
+ * there may be long delays between the end of one buffer and the
+ * start of the next.
+ *
+ * Since usually the network allows data to be sent at
+ * faster than realtime, and rtmpdump wants to download the data
+ * as fast as possible, we use this RTMP_LF_BUFX hack: when we
+ * get the BufferEmpty message, we send a Pause followed by an
+ * Unpause. This causes the server to send the next buffer immediately
+ * instead of waiting for the full duration to elapse. (That's
+ * also the purpose of the ToggleStream function, which rtmpdump
+ * calls if we get a read timeout.)
+ *
+ * Media player apps don't need this hack since they are just
+ * going to play the data in realtime anyway. It also doesn't work
+ * for live streams since they obviously can only be sent in
+ * realtime. And it's all moot if the network speed is actually
+ * slower than the media bitrate.
