Raspberry pi stream controller

A Remote Control Interface for video transmitters

1. Installation

$ git clone git@github.com:OAlm/rbpiCC.git
$ npm install

2. API

/api/pies

Returns ids of connected transmitters

/api/:proto/:method?id="id"

proto is the protocol/application to be used: wowza or gstream.
method is method that is to be called: start, stop or status. Defined on transmitter.

Additional parameters that interface accepts

Wowza
- host - ip address of Wowza streaming engine
- port - port number of Wowza streaming engine incoming rtsp streams
- app - application name defined in Wowza streaming engine
- resolution - video resolution to be transmitted by transmitter
- vf - vertical flip of the camera true or false
- hf - horizontal flip of the camera true or false
Gstreamer
- sink - ip address of destination sink
- port - port number of the destination sink
- resolution - video resolution to be transmitted by transmitter
- vf - vertical flip of the camera true or false
- hf - horizontal flip of the camera true or false
Example:
/api/wowza/start?id=0003656&host=000.000.000.000&port=80&app=myApp&resolution=10x10&vf=false&hf=true

3. Improvements

There is no authentication nor authorization when accessing the http api.
The api can be extended to work through web sockets.
Meaning the connection will be ClientSocket -> ServerSocket -> ClientSocket
in addition to existing HTTP_Client -> HTTP_ServerSocket -> ClientSocket
Reason behind having HTTP_Client is the simplicity behind high level of control. If more complex control is to be implemented, then socket connections are the way to go.

4. Gstreamer

To view the stream with the gstreamer:
gst-launch-1.0 -e -v udpsrc port=0 caps="application/x-rtp" ! rtpjitterbuffer ! rtph264depay ! avdec_h264 ! fpsdisplaysink sync=false text-overlay=false
