=========

[](https://github.com/gabrielmagno/nano-dlna/blob/master/LICENSE)
A minimal UPnP/DLNA media streamer.
nano-dlna is a command line tool that allows you to play a local video file in your TV (or any other DLNA compatible device).
🦀 **Note**: also checkout [crab-dlna](https://github.com/gabrielmagno/crab-dlna), a Rust implementation of nano-dlna.
Features
--------
- Searching available DLNA devices in the local network
- Streaming audio
- Streaming video, with subtitle support
Usage
-----
### List
Scan compatible devices and list the available ones:
nanodlna list
If your device is not being listed, you might need to increase the search timeout:
nanodlna -t 20 list
### Play
Play a video, automatically loading the subtitles if available, selecting a random device:
nanodlna play That.Movie.mkv
Play a video, specifying the device through query (scan devices before playing):
nanodlna play That.Movie.mkv -q "osmc"
Play a video, specifying the device through its exact location (no scan, faster):
nanodlna play That.Movie.mkv -d "http://192.168.1.13:1082/"
Installation
------------
nano-dlna can be installed as a regular python module by running:
$ [sudo] pip install nanodlna
Technical Details
-----------------
nano-dlna is basically a one-file DLNA MediaServer and a self DLNA MediaController.
How does `list` work?
1. Issue an SSDP M-Search broadcast message in the network
2. Capture the responses and register the devices
3. Filter only devices that provide [UPnP's AVTransport service](http://www.upnp.org/specs/av/UPnP-av-AVTransport-v3-Service-20101231.pdf)
How does `play` work?
1. Setup an HTTP server to provide the media files to be streamed (including subtitles)
2. Send a `SetAVTransportURI` message to the device, specifying the HTTP URLs of the media files
3. Send a `Play` message to the device
TODO
----
- [ ] Documentation
- [ ] CLI interface to send controller actions (play, pause, stop, etc) to the MediaRenderer
