+According to [this conversation](http://gstreamer-devel.966125.n4.nabble.com/flvdemux-working-sometimes-td4677796.html), the following also works, although personally I find it intermittent:

+
+### Adding an RTMP as picture-in-Picture
+
+This overlays an RTMP source as a picture-in-picture on top of a local filesource (set as `$SRC`)
+
+```
+gst-launch-1.0 \
+    filesrc location="$SRC" ! \
+    decodebin ! videoconvert ! \
+    videoscale ! video/x-raw,width=640,height=360 ! \

+
+
+## Sending to an RTMP server
+
+### Sending a test stream to an RTMP server
+
+This will send a test video source:
+
+```
+gst-launch-1.0 videotestsrc  is-live=true ! \
+    queue ! x264enc ! flvmux name=muxer ! rtmpsink location="$RTMP_DEST live=1"
+```
+
+This sends both video and audio as a test source:
+
+```
+gst-launch-1.0 videotestsrc is-live=true ! \
+    videoconvert ! x264enc bitrate=1000 tune=zerolatency ! video/x-h264 ! h264parse ! \
+    video/x-h264 ! queue ! flvmux name=mux ! \
+    rtmpsink location=$RTMP_DEST audiotestsrc is-live=true ! \
+    audioconvert ! audioresample ! audio/x-raw,rate=48000 ! \
+    voaacenc bitrate=96000 ! audio/mpeg ! aacparse ! audio/mpeg, mpegversion=4 ! mux.
+```
+
+### Send a file over RTMP
+
+```
+gst-launch-1.0 filesrc location=$SRC ! \
+    qtdemux name=demux \
+    demux.video_0 ! queue ! \
+    decodebin ! videoconvert ! x264enc bitrate=1000 tune=zerolatency ! video/x-h264 ! h264parse ! \

+    audio/x-raw,rate=48000 ! \
+    voaacenc bitrate=96000 ! audio/mpeg ! aacparse ! audio/mpeg, mpegversion=4 ! mux.
