rtsprelay
===

RTSPrelay relays a video stream provided by an RTSP RECORD session to one or
more PLAY sessions. It is intended as a proof of concept and has several
limitations.

* Only H264 video and MP4A-LATM audio streams are supported.
* No authentication/authorization.

## dependencies

* gstreamer-rtsp-server-1.0
* gstreamer-1.0
* gst-plugins-good-1.0
* gst-plugins-bad-1.0

Example pipelines additionally require:

* gst-plugins-ugly-1.0
* gst-libav-1.0

## build

To build simply type `make`. This will create the binary `build/rtsprelay`

## run

The binary `rtsprelay` accepts several arguments. Run with `-h` for details.

## test

To test you must create a RECORD session and one or more PLAY sessions. The endpoint
is dynamically created based on the first element in the uri path.

You may need to update the rtsp location and encode/decode parameters for your environment.

### record

A record pipeline. Video must be the media element 0.

```
gst-launch-1.0 autoaudiosrc ! audioconvert ! queue ! faac ! \
  r. autovideosrc is-live=1 ! queue ! \
  x264enc tune=zerolatency byte-stream=true threads=1 key-int-max=15 intra-refresh=true ! \

  rtspclientsink debug=1 latency=0 location=rtsp://127.0.0.1:8554/test/record name=r
```

### play

A play pipeline.

```
gst-launch-1.0 -v rtspsrc debug=1 latency=0 location=rtsp://127.0.0.1:8554/test name=r r. ! \
