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 ! \

mix.
```
## 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
